how to create dynamic blocks in VBA

bkovan — Mon, 21 May 2018 20:20:55 GMT

Hi, I am looking to see how to create a dynamic block in VBA?

Essentially, I want to import a dynamic block, add or remove actions, and save it (re-create it).

I understand how to create a regular block, how do you import the dynamic block properties, actions, stretch etc.?

There is no API exposed/supported in AutoCAD's COM/.NET API for defining block's dynamic properties. So, no, you cannot use VBA to do what you want.

You may have to resort to using lisp entmake called from your vba take a simple dynamic block say a rectang and pull it apart. Getting into the extended parts about constraints.

You should be able to do with VBA I just created a dynamic object from scratch that has a dynamic radius , my reference was code from Togores, Reinaldo N.. Programming 3D. Solids, Meshes & Surfaces. (AutoCAD expert's Visual LISP) a book I bought from Kindle for a few dollars well worth the investment.

make a shape then use

(vl-cmdf "_AutoConstrain" (entlast) "")

(vl-cmdf "_DcRadius" (getpoint "p1")(getpoint " p2")) add other constraints.

(vl-cmdf "_DcVertical" (getpoint "p1")(getpoint " p2"))

You can't create dynamic blocks using VBA. However, you can create a dynamic block with AutoCAD and then insert it into a drawing modifying it's properties. Cheers!
