Title: Finding objects inside INSERT/BLOCK
Post by: Woabow on May 13, 2013, 01:47:11 PM

There are several routines that lists the contents of a BLOCK. They will return the same data for any instance of a BLOCK in the drawing.

But what if I would like to have the contents of the INSERT, or in my case, I just want to have a list with all lines inside an INSERT with the drawing-WCS-coordinates of the lines.

Do I have to find the contents of a BLOCK first and "multiply" it with the INSERT matrix?

Great :cry:

Our blocks are often nested, gives me headaches... Maybe it is easier to explode the blocks with an undo mark, collect the info and do an undo....

This program may help you with the matrix transformations: Extract Nested Block (http://lee-mac.com/extractnestedblock.html), the key is gile's refgeom function.
