In AutoCAD Electrical we have the power to update title block of a drawing or project with a click of a button. Unfortunately some setting must be done for all this to be possible, but we do it once and that’s it, unless more then one title block is used. Below represent the different setting that are possible in our “Title Block Link Method”. Before I explain to you what the method are I must let you know the file that controls the title block update has the extension WDT. In this WDT file, which can be read and edited as a text file in notepad, it contains the block attribute and what are they link to in ACADe.
This “Title Block Link Method”, found in the drop down menu “Projects” under the name of “Title Block Setup”, shows us 2 methods. Method 2 is actually an attribute inside of your title block containing your links, which for me I found harder to control and editing on the fly, also your attribute name must be named WD_TB. Method 1, which I use religiously and find it easier to control, offers us 3 options.
Option 1, this option is project specific, in other word you need to have a WDT file with the same name as your project i.e. Project = DEMO.wdp, Title Block Link = DEMO.wdt.
Option 2, this option is kind of project specific also, the only difference, you have a WDT file named default.wdt in the project folder. If you have more then one project in a folder, they would all share the same default unless you created a specific project WDT.
Option 3, this option is more Title Block specific, what do I mean by that? If your company uses the same title block over and over, with little changes over the year, this is the option for you. You would name a default.dwt file in your support folder of ACADe. That way if the title block update doesn’t find a project.wdt, or a default.dwt in the project folder, then it would look in the “C:\Program Files\Autodesk\Acade 2006\Support”. Instead of having different DWT per project, which you are using the same title block over and over, then option 3 is your best bet.
In the “Title Block Link Method”, if you choose to use Method 1, the one that you have selected doesn’t really matter, why? Because ACADe searches for all of them but in the order of, project.dwt, then default.dwt in project folder, followed by default.dwt in the support folder and if none of these are found, it will go to method 2 which is the WD_TB attribute.
I hope this is useful information for you to start setting up your company WDT standard, but also this work for your WDL extension.
Good luck with you Title Block Update,
