Using COM , Bricscad / IntelliCAD commands can be defined using Application.DefineFunction
It is similar to (defun c:cmd) in LISP.
I used this with vb6 and (CMS) IntelliCAD and now I've tried to translate into .Net (and works)
In vb6, is very easy. We use the addin wizard
This is the same as creating a shared addin for office using visual studio 2008. The big difference is for the registration of adddin, with. Net must be done explicitly (by code)
-To debug the same as with AutoCad
-For manage COM addins in bricscad use the command _addinmanager
I do not explain more because I do not speak English
