Hello .
I have a few questions and hope that someone have willing to help me with them .
As posted by fixo .
(vl-catch-all-error-p
(vl-catch-all-apply '(lambda (x) (setq newss (vla-add x ssnam))) (list ssobj))
)
1- the ssobj is added to the named selection set argument ( ssnam ) .
and below in the same code , they deleted ssobj from the ssnam and after that they re-add it to the ssnam , this is odd to me ?
(vla-delete (vla-item ssobj ssnam))
(setq newss (vla-add ssobj ssnam)))
2- What's the meaning of variant function ?
(vla-additems newss (variant safe))
Many thanks in advance .
