Demo: Select (Panel) Lines which are Open or Closed (Precast, AutoCAD .net)
Sometimes we have a need to identify – and quickly – lines which are open and lines which are closed – especially prior to running any operations on those lines involving regions. Here is a demo of a little plugin I wrote. It goes through the modelspace and finds all the line segments which are…

How to Easily Compare Precast Panels in AutoCAD (Precast)
Suppose someone makes a change in the layout but forgets to do so in the shop drawing (and vice versa). If you move a cast in plate, and if it’s actually produced and taken to site, then you have a big problem, and a big cost. How are you going to identify the differences…

Demo – Create Revit Panels Directly From AutoCAD Panels (Precast)
This is a demo of my latest plug-in which demonstrates a proof of concept – i.e. a MVP (Minimum Viable Product). The programming was a little trickier than normal – because we are not using the .NET API, but the COM Interop API and the Revit API – something which I have not really explored…

The Curious Case of Overkill Not Working (AutoCAD)
A very perplexing question: Why isn’t overkill working? The result will stun you. As you can see in the above picture, the top row of panel voids were doubled and in some cases tripled up. Obviously we don’t want this. Ordinarily, when such drawings are passed on to us we employ the overkill command. But…

Turning AutoCAD curves into Revision Clouds (AutoCAD .net API)
It seems a common scenario that folks want certain polylines/curves etc to turn into a revision cloud. How do we do this? At the end of the day, the revision cloud is nothing but a polyline. You could roll your own polyline which handles the bulges and vertices so that it looks like a revision…
