Topic: Replicate Autoconstrain command in AutoLISP

[jtm2020hyo]

Does someone know if exists any AutoLISP routine to do exactly what _Autoconstrain command does? if yes, please share the link.

Applications:

A simple application is in AutoCAD architecture and MEP, here exist objects has walls and columns, actually us possible use manual constraints but the autoconstrain command do nothing.

 

... And a autoconstrain.LSP could be create then could be recicled for multiple applications in different objects, included in Civil 3D or maybe Advanced Steel.

applications in different objects, included in Civil 3D or maybe Advanced Steel.

Very Easy.
a)You open the file jtm2020hyo.dwg.
b)You set color RED for one-object.
c)You clone one-object. (or duplicate)
d)You set color GREEN for last object c)
e).You develope a programe.lsp (compare objC and objA)
