SSGET - syntax for select enti

MastroLube · 发表于 2022-7-5 19:54:40

Hello everyone,
I want to select only polylines in the layer "VP" in a region.

Is it possibile using ssget?

I've tried with:

copy

(ssget "_C" pnt_A pnt_B '((0 . "LWPOLYLINE") (-4 . "=") (8 . "VP")))

but it doesn't work :/ (i get a nil)

Any idea?

Thanks, Dennis

Do the variables pnt_A and pnt_B representing correct coordinates ?

Then remove the (-4 . "=") from the codes and try again .

You're right, remove (-4 . "=") do the trick!

I've read about (-4 . ...) here http://www.lee-mac.com/ssget.html but maybe it's not for this type of argument..

Thanks. man )

You are welcome

When you need any information about any function and while you are in Visual Lisp editor , just press ctrl+F1 then write the name of the function to get the help document opened and direct you to the required function , or just highlight the function and press ctrl+F1 .

Good Luck .
