Naming Dims in autocad

Anonymous — Fri, 14 Jun 2013 17:55:06 GMT

Hi all,

Using the API, is it possible to "name" dims in a 2D drawing and, based on what the dim is "named" preform math on the dim and display the result nest to the existing dim?

What API are you taking about (COM/ObjectARX .NET/LISP/ObjectARX C++)?

Dimension object in different APIs does not have "Name" property. However, you can attach XData/ExtensionDictionary to tag the dimensions in interest. Then later you can search for dimensions in drawing by the attached data and do things you need from there.

Thanks for the reply. I do not know what type of API, as I am mainly doing research to see if what I need done is even possible. The "name" property would not be necesary, only a way to differentiate between different dims in order to specify what functions to preform on the value of the dim.

What you are asking is possible in LISP, VBA, .NET and ObjectARX. If I were you, someone who knows VBA I'm guessing, I'd go to VB.NET and use the ActiveX API using COM interop - that way you are using .NET with your familiar VBA functions and libs
