Maybe these values would be of help to you?

Code: [Select]

; Property values:

Code: [Select]

(setq ent (entsel "\nSelect an object: ")
obj (vlax-ename->vla-object (car ent))
)
You process the info by taking the property name, i.e. "PrincipalDirections" and adding vla-get- in front of it.

Code: [Select]

(setq PDir (vla-get-principaldirections obj))HTH. Give this a shot in your vlide. It will help you see all the things that are exposed when you inspect your code.
