Thank you for your answer
xycadd !
Your guess was exactly what I was looking for (sorry: my english is not as good and fluid as I would, and sometimes I can't express myself properly
).
I've used (C:VLIDE) for open it, and it works. I'll try the way to start it you've post, and compare both (probably yours is better).
Although you consider it tricky, and if it is possible, iId like to have a look on how to close the VLIDE with LISP.
Would you, please, post it?
Thank you very much again!
