is ther any way to merge lisp with parametric constrain?

[jtm2020hyo]

1 How can I use "Auto Constrain" with AutoCAD Architecture or AutoCAD MEP objects? (wall, columns, etc)?

2 is this possible with LISP?

3 Does anyone know if exists any LISP related to this?

Can you give an example of what you would like to do?

The following uses AutoCAD's parametric features and vlisp to animate a 4-bar linkage.

I wish ad exactly what auto-constrain do with lines or polylines or another object but with AutoCAD Architecture / MEP objects.

a wall is an object, I wish to select all walls and then if they are parallel to others, the auto-constrain should create a parallel contain, if they have same vertex the coincident constrain should apply.
