Yes ControlDraw 3 is now free. You can downloaded it and use it indefinitely without having to obtain a license. And you won't have to wait to obtain a license to use CD in it's full glory!<br />
<br />
Why do this?<br />
Existing users will no longer need to get a new license when they change their PC.<br />
Existing plants which have CD in their documentation will be able to provide support for it.<br />
Educational institutions can freely use it.<br />

There are also new websites made using ControlDraw's fairly new Export as Web function, take a look at <a href="http://controldraw.com%20/" target="_blank">controldraw.com </a> and new examples of ControlDraw models in the form of webs that you can see at <a href="http://controldrawltd.co.uk/" target="_blank">controldrawltd.co.uk</a><br />
This ability to make web from models makes models easily accessible to people who have neither ControlDraw or the ControlDraw Reviewer.<br />

Here is it, and the Reviewer in the Windows 8 Start Screen.<br />
<div class="separator" style="clear: both; text-align: center;">

<br /></div>
Of course it runs in the desktop, not as an App. <br />
Here it is starting up. This screen also shows the Win8 Task Manager, which is so much better than previous versions of Windows. It also shows a file copy in progress, again this is a much dialog.<br />

No, it won't work in Windows RT, sorry.ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-61732151477619519302013-02-14T16:06:00.003+00:002013-02-14T16:09:22.993+00:00Loop and Logic Diagrams and P&ID’s<span style="font-family: Arial, Helvetica, sans-serif;">This has recently been discussed at length on LinkedIn on the ISA – International Society of Automation group under the title "Does control logic belong on P&IDs?"</span><br />
<br />
Among the comments are<br />
<em>....Adding logic functions to a P&ID clutters it, is prone to add further unnecessary revisions to the P&ID every time a logic is changed ...</em><br />
<em>...agree that the complexity that we can configure into the DCS, PLc, and SIS cannot be represented adequately on the P&IDs...</em><br />
<em>...No, detail logic does not belong to PIDs. A PID is a construction document, as such it must show:</em><br />
<em>1-Hardwired input to logic interlock, complex loop or DCS/SIS</em><br />
<em>2-Hardwired output from logic interlock, complex loop or DCS/SIS to Final Control Element FCE</em><br />
<em>3-Identification of logic interlock, complex loop or DCS/SIS. Separate documents are generated for interlocks and complex loops...</em><br />
<br />
<span style="font-family: Arial, Helvetica, sans-serif;">So, h</span><span style="font-family: Arial, Helvetica, sans-serif;">ow much can reasonably be shown on the P&ID depends on the type of process and previous practise but at the end of the day there are nearly always extra diagrams, typically with a cross reference on the P&ID.</span> <span style="font-family: Arial, Helvetica, sans-serif;">This blog post provides an explanation of how you can use ControlDraw to draw all those extra diagrams and relate them to the P&ID's</span><br />
<span style="font-family: Arial;">Top level diagram contains an object for each P&ID and child pages then provide a graphical list of the relevant loop and logic diagrams which are then diagrams under each object.</span><br />
<span style="font-family: Arial;">Here is a diagram that explains this (click to see full size)</span><br />
<div class="separator" style="clear: both; text-align: center;">

And you can create all the P&ID Overview diagrams with a couple of clicks from the Group Menu >Create/Link Child diagrams.</span>ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-61424320399053109392012-09-03T14:05:00.001+01:002013-02-14T15:07:11.633+00:00ControlDraw Model to Web Site<br />
ControlDraw now provides the ability to generate a web site from the model.<br />
This means that people will be able to view a model without the need to install any software or work from PDF output from the Reviewer.<br />
The web version is of course much simpler than the original model and does not support such functions as running diagrams in simulation mode. However it is still useful.<br />
Example is available to view <a href="http://www.controldrawltd.co.uk/">here</a>.<br />
You can click on the objects that have numbers by them to go to the detailed diagram for the object,much like you can in ControlDraw itself<br />
<br />
Each web page is a diagram page in the ControlDraw model. <br />
Each ControlDraw diagram page is saved as a png file including automatic generation of the hot spots as an HTML ImageMap <br />
The page description HTML was generated from the page RTF text<br />
<br />
A more advanced version will soon be available that supports navigation view with a Hierarchical menu<br />

As Windows has developed and computers have arrived with large High Resolution displays, the standard size of the various ControlDraw windows has remained the same. This has had the effect of making them too small for some users and furthermore the latest versions of Windows 7 have a larger default font size. As a result some users were finding that the text in the labels and button etc in the ControlDraw windows did not fit the available space.<br />
The latest version of ControlDraw now provides a solution by providing a selection at the Login screen.<br />
As you change the option you can immediately see the effect. <br />

<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">The Recipe Modelling developments are mainly intended to support recipes that can have a large number of parameters. For example the Descended Objects view can be used to create parameters in a Recipe Procedure by scanning all the child hierarchy of a recipe type diagram and finding all the lower level parameters (typically in Phases or Operation) and making copies of them.</div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzD_aAjjBmLRfuPd4iilVcdjvWVVSyuRGQkYv5J4bygrKuMTWiNa7BsDAfqoEWs1p9BvblSe9fahFp4juJJpfP2S41DCtHSKut-wmRxqr6rptmbwClDBWtcreyMO6eUg0maqpSLRTqzt8/s1600/CDDescendedObjects.PNG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="171px" j8="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzD_aAjjBmLRfuPd4iilVcdjvWVVSyuRGQkYv5J4bygrKuMTWiNa7BsDAfqoEWs1p9BvblSe9fahFp4juJJpfP2S41DCtHSKut-wmRxqr6rptmbwClDBWtcreyMO6eUg0maqpSLRTqzt8/s400/CDDescendedObjects.PNG" width="400px" /></a></div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div>The improved Diagram List view - this now shows the link page and link type and allows you to change them and to change object classes.<br />
In addition it is now possible to view and hide/unhide diagram objects from the List View. <br />
Hidden objects do not appear on diagrams but still generate data. <br />
If a diagram has hidden objects a count of them automatically appears on the diagram. There is also a new special symbol, 'Hidden Symbols' that you can put on a diagram to show a list of them<br />
<br />

This is mainly intended to support things like recipes that can have a large number of parameters that you still want in the data tables. </div><br />
The improvements with handling large models are mostly speed, large diagrams load much faster and the data build process has been accelerated. Where ControlDraw used to read the records and rebuild all objects when a diagram was opened and then save all the records when the diagram was closed, it now (optionally) only reads and updates on a symbol basis. For large diagrams the improvement is large, a complex diagram with about 200 objects including a large state matrix now loads in under 2 seconds compared with 8 seconds on a 3 yr old PC that is not state of the art.ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-29305958598132124742011-05-22T18:05:00.000+01:002011-05-22T21:38:49.115+01:00Pharmaceutical Fermenters<div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">I have recently been looking at ControlDraw models for large scale Pharmaceutical Fermenter Units from 4 different companies.

Often these documents can become superseded by a model, but it is always useful to be able to refer back to them, to ensure traceability and to be able to check back. Keeping track of these can be tedious.ControlDraw has long supported simple hyperlinks, provided you had a web or file address on the first line of an object's text. This has been greatly improved recently.<br />You can now set a Linked Documents Path that is a top level folder that contains all the documents that you want to be able to open from a model.<br />You can also copy File Names in Explorer and then paste them as hyperlinks.ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-6757301938077361292010-04-15T18:05:00.000+01:002010-04-15T18:20:07.064+01:00The Transfer Route QueriesYou may not know about this although it has been possible for a long time<br />If you draw a diagram that shows connections between units via common resources there are standard queries that can show a table of the routes, including those that go from unit to unit (single level) , those that go from onne unit to via another unit to the last unit (2 levels) and those that go from a unit to another via two units (3 levels).<br />The diagram below show a simple example.<br />For convenience the single level and two level queries are also shown on this diagram using FAV: UserQuery special objects.<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Lkpb-jYJE5lD-OQaW0gCryufnOlwieeN9OwYY0S7KcI3u9MGPNFjNOGKt0zsBE_5fA9V_HC0EVd6nE8F-MSbFcD1xxswFQXV2Csfa06TC9ocfAUGGwg2eqodZLA5LSIb63hfA0ncOQE/s1600/TransferQuery.PNG"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 400px; DISPLAY: block; HEIGHT: 242px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5460412730154227874" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Lkpb-jYJE5lD-OQaW0gCryufnOlwieeN9OwYY0S7KcI3u9MGPNFjNOGKt0zsBE_5fA9V_HC0EVd6nE8F-MSbFcD1xxswFQXV2Csfa06TC9ocfAUGGwg2eqodZLA5LSIb63hfA0ncOQE/s400/TransferQuery.PNG" /></a><br /><div></div>ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-62332081242708843222010-04-14T15:49:00.000+01:002010-04-14T16:20:14.122+01:00New - Tag BalloonsThe latest version of ControlDraw provides a new way of attaching text to symbols, these are call Tag Balloons and are based on the ISA tag symbols for P&ID's.

And as they are intended to identify every single instrument, the tags have to be unique.<br />More than that, the tags always have some meaning, providing a clue as to the purpose and location of the instrument.<br />Tag naming is one of the first things you need to understand when you start a new project, because most projects have different ways of tagging.<br /><br /><strong>How are Tags constructed?</strong><br />Generally they have a letter prefix, a number or code, and often a suffix.<br />Conventionally these tagnames were allocated by instrument engineers whilst at the same time keeping a record of the used tag names in an Instrument Index. More modern CAD systems may keep the index and tags at the same time.<br />The ISA S5.1 <a href="http://www.engineeringtoolbox.com/isa-intrumentation-codes-d_415.html">ISA S5.1 standard, codes for Process Instrumentation</a> provides a basis for the letter parts, but not for the number part, and methods of assigning these vary from company to company and even from plant to plant. You can always work out that PIC (or maybe PC) means a pressure indicating controller. But the next part, 1299 say or r123- or whatever is not obvious. Whenever I start working with P&ID I ask for the Equipment/Tagging standard, no two are the same! The standards cover much more than just instruments, for example equipment tags (R for reactor etc), the Area numbers and much more has a company standard. I get bored by the pipe naming.<br />One classic scheme is to number the instruments within the P&ID, and with part of the P&ID number in the tag. Often In turn the P&ID drawing number contains a higher level, say an area.<br />So we might have TIC3012-5 where 30 is the area, 12 indicates the twelfth PID in that area and 5 is the fifth Temperature measurement on the P&ID.<br />A more advanced scheme used by many practitioners is to base Tags on the Equipment number, so the Tags relate to the equipment, and even better so that if there are several similar equipment items the tags within each are the same.<br />For example, V3249-01 (or perhaps R3249-V01) might be the first valve in reactor R3249, V3250-01 the first valve in reactor R3250, and so on.<br />Some also have a standard so that similar items have similar sub-number, even in different type of equipment, for example Discharge valves are always V####-01<br /><br />But when it comes to describing – or even programming – a controlled entity such as a<br />Unit or Equipment module, it is very useful to have some things that the classic method does not cover. One is Tagnames that are consistent within objects so when you look inside two similar objects (say 2 reactors) the Tags are the same – at least when you exclude the part that identifies which reactor. Then you only have to use nice short names. like V01 or FC02. It can save a lot of time.<br />Another issue is that, on an HMI, long tag names are unfriendly and clutter the screen. Yes, the best graphics have an option to not display the tagnames, but when you do show them short ones are easier on the eye. And combining Equipment based tagging with Unit relative graphics makes it possible.<br /><br />The ISA letter parts have a problem - they are based on a very old concept – panel instruments.<br />In particular the use of the A for alarm letter has become almost a distraction. The A letter meant something in the old days, it might imply a need to use a trip amp and an annunciator lamp, things that had to be purchased. Now, everything can have an alarm, do you really want to change the P&ID because you added an alarm?<br />Similarly using I to show that something should be displayed? I would hope that everything should be displayable.<br /><br /><br />The reality is often that there are inconsistencies in the P&ID tag names, even when the tagging scheme is equipment based. (For example when the P&ID tagging has a shared common resource ‘inside’ the first equipment that uses it)<br /><br /><strong>What’s all this got to do with ControlDraw? </strong><br /><br />ControlDraw provides several ways to handle this:<br />The External Tag can be set to match whatever the P&ID tag is.<br />Variants can often be used to reconcile inconsistent tags<br />Clones can be used to position an object within the P&ID Equipment but still in the right module<br />Scripts can extract the information from the tag and use it consistently.<br /><strong></strong><br /><strong>Extract the meaning of the Tags with Scripts</strong><br />Now, whatever the tag naming scheme, there is always some useful information contained within the tag name. And ControlDraw provides several useful ways to deploy that information. The most powerful is by using Scripts.<br />The Scripts can use parts of the hierarchy of tagnames, for example to set the Engineering Units according to the instrument letters.<br />TagPrefix0 is the first letters of the lowest level in the hierarchy of tagnames<br />Select Case TagPrefix0<br />Case "FT","FI","FIA"<br />CalcTag = "m3/hr"<br />Case "PT","PI","PIA"<br />CalcTag = "Bar"<br />Case "TT","TI","TIA"<br />CalcTag = "DegC"<br />Case "LT","LI","LIA", "CV", "FCV", "LCV","PCV", "TCV"<br />CalcTag = "%"<br />Case Else<br />End SelectControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-59736193646033459862009-09-21T12:15:00.000+01:002009-09-21T12:19:23.466+01:00Process Flow Sheets with ControlDrawDid you know that ControlDraw can produce Process Flow Sheets that show process flows and the material properties for equipment and lines.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNof1c-UvLBgjX4efixS1FQa0WXpmpLuOd9HjwoHAb4qxJOl5zfbBT1pgqeeKj1_1ImC2woJBKTLqX4b2J_KHsyfYixYH_l3saot-WLgcYnmEPIZfWJdZk8hJBGZaoaTmxLXDS2YsBLyo/s1600-h/pfdtank.PNG"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 337px; DISPLAY: block; HEIGHT: 112px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5383878057049904162" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNof1c-UvLBgjX4efixS1FQa0WXpmpLuOd9HjwoHAb4qxJOl5zfbBT1pgqeeKj1_1ImC2woJBKTLqX4b2J_KHsyfYixYH_l3saot-WLgcYnmEPIZfWJdZk8hJBGZaoaTmxLXDS2YsBLyo/s400/pfdtank.PNG" /></a> This is achieved by using Symbol Data - name value pairs that you can set for each symbol, or by a matrix.<br />An example and explanation is provided in the latest Sample Models.<br />And of coure, like pretty well everything in ControlDraw (and unlike say Visio) the data becomes available for use in Queries and even calculations.ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-52302459795669969082009-09-21T12:02:00.000+01:002009-09-21T12:11:53.322+01:00Tips on Drawing Diagrams<div><strong>Swap two objects: </strong><br />You can very quickly swap two objects by dragging one onto anotherr.<br />An example might be where you want to move a step in an SFC.<br />Normally the Swap option is only offered when the two objects have the same class but if you hold down Shift then it apples to objects of any class<br /></div><div><strong></strong> </div><div><strong>Centre Connections:<br /></strong>If you want to centre the connections between symbols it is very easy using the Centre all connections option in the Group More menu, this will place all the connection points at the mid point of the side they are on. </div><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 400px; DISPLAY: block; HEIGHT: 216px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5383875039666168290" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQTvZJ3GEaO4t6vKeb7q6dqsVHHIe7lJxwXepmUzy-ogcu9_OViDttBPIrEZSrP3xUOOeaGMLyTBEhqi9GV8mLd0KH1XixQEb1pJz5CX5pOZtUtvvYES9lXF1i5oD49juDbHOD4XKy8as/s400/CentreConnections.PNG" /><br /><div><br /><strong>Change Case</strong></div><div>It is really annoying to find that the text you have just typed is all in UPPER CASE!<br />Well, just like MS Word, with ControlDraw it is easy to fix, just use Shift-F3 and the text (for example a Tagname or Object description) will toggle between Upper, Lower and the First Letter Upper and the rest lower.</div><br /><div></div><div><strong>Editing Line Positions</strong></div><br /><p align="left"></p><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgE7MwCKxF6kHkAcSgRGw1x-EHJBXqvnyKbFjdjeZoCAxUbK69AZVxyJWddxlATGJMfCV13i34BcpDHxJfemr0rbI1bDESBvF61fFfnRPgyXKaCAqppxKt5Q1Ol0khzYpwK2QJn4aIStrk/s1600-h/EditLines.PNG"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 118px; FLOAT: left; HEIGHT: 185px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5383876434917561714" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgE7MwCKxF6kHkAcSgRGw1x-EHJBXqvnyKbFjdjeZoCAxUbK69AZVxyJWddxlATGJMfCV13i34BcpDHxJfemr0rbI1bDESBvF61fFfnRPgyXKaCAqppxKt5Q1Ol0khzYpwK2QJn4aIStrk/s400/EditLines.PNG" /></a>Double click a line and if it has more that two segments each segment that is not at an end of the line shows a number in the middle.

Each Instrument should be linked as a parent to the relevant Instrument Type Diagram.<br />It is with the more recent versions of ControlDraw very quick to create the diagrams for each area/room<br />So if the first diagram is a Layout like this (each has the class Unit)<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9tahDpLUPIFvcoZibwIr83F7eryykKV01Hz_lV8E4LyDFX4gYL6ndcVgx_lfgNTHCnKSg1S8MbMc4ha9uD_clp_qO38g6d_XtL2-sfzZJKLkt5tdSSV5QQm6tY8d6tUHc2C8Gn_f15zo/s1600-h/PlantAreas.JPG"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 400px; FLOAT: left; HEIGHT: 151px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5359120584645368098" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9tahDpLUPIFvcoZibwIr83F7eryykKV01Hz_lV8E4LyDFX4gYL6ndcVgx_lfgNTHCnKSg1S8MbMc4ha9uD_clp_qO38g6d_XtL2-sfzZJKLkt5tdSSV5QQm6tY8d6tUHc2C8Gn_f15zo/s400/PlantAreas.JPG" /></a><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />You can select all and then in the Group Tool use >More >Create/Link Child Diagrams<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAYjdU6FZi-2iuqk3Chu64OYdi4pNAMjSqMssDpKypath-QOz_f1Hpq3yzEkCVTcyu8quzIWX9sZXM9v7HHQGjErmxom7wy1zfZD-o9Ca5ey1G8G-ex5F8ZRonNelronhg2BHxmR4AVlI/s1600-h/GenerateChildPage.JPG"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 400px; FLOAT: left; HEIGHT: 194px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5359123186829510386" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAYjdU6FZi-2iuqk3Chu64OYdi4pNAMjSqMssDpKypath-QOz_f1Hpq3yzEkCVTcyu8quzIWX9sZXM9v7HHQGjErmxom7wy1zfZD-o9Ca5ey1G8G-ex5F8ZRonNelronhg2BHxmR4AVlI/s400/GenerateChildPage.JPG" /></a><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Result<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWk0uTEnUgOF_oKkVihyphenhyphen-jkn7XT1OgHEmjqow9BVTnXz6ApfyiFlSJFnZ5s4zJjWNjl2BzhFmTjmnpjtCOh-s7UZ7tr_JuUKlv903HeAx93QTms0f4xdNG_kbY4NhUNwrrrMkttRtvOAU/s1600-h/GenerateChildPageresult.JPG"><img style="MARGIN: 0px 10px 10px 0px; WIDTH: 430px; FLOAT: left; HEIGHT: 149px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5359124069335144386" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiWk0uTEnUgOF_oKkVihyphenhyphen-jkn7XT1OgHEmjqow9BVTnXz6ApfyiFlSJFnZ5s4zJjWNjl2BzhFmTjmnpjtCOh-s7UZ7tr_JuUKlv903HeAx93QTms0f4xdNG_kbY4NhUNwrrrMkttRtvOAU/s400/GenerateChildPageresult.JPG" /></a><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Then place instruments in each room.

And for a short time licenses are available at lower costs. Furthermore and as previously mentioned there is now a New licensing model.<br />This includes licenses for use on smaller projects so that smaller companies can get all the benefits of using ControlDraw at a much lower cost than before.<br /><br />For example, Starter Licenses provide all the modelling that a full license provides but with limits on the overal size of the model. These are still enough for a small process cell with a couple of units defined in great detail.<br /><br />There are also very cheap licenses for students and personal users.<br /><br /><a href="http://www.controldraw.co.uk/purchasing_controldraw.htm">Online purchasing</a> is also now available.ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0tag:blogger.com,1999:blog-8954615698408448814.post-24349711569224045722009-05-22T21:48:00.000+01:002009-05-22T21:58:40.677+01:00New licensing model lower cost<span class="Apple-style-span" style="font-size: medium;">ControlDraw will soon be announcing a new pricing scheme for our users</span><div><span class="Apple-style-span" style="font-size: medium;">This will include very low cost licenses for personal users and students, and lower prices for small companies such as systems integrators.</span></div><div><span class="Apple-style-span" style=" white-space: pre; "><span class="Apple-style-span" style="font-family:arial;"><span class="Apple-style-span" style="font-size: small;">ControlDraw has now completed 10 Years in business</span></span></span><span class="Apple-style-span" style="font-family:arial;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></div><div><br /></div>ControlDrawhttp://www.blogger.com/profile/07233915024225686097noreply@blogger.com0
