select all entities that make up a block

[paolomath]

Good morning, everyone.

I started playing a little with lisp...

in the hypothesis of wanting to change one of the graphic objects that make up a block (lines, circles, etc.) in a programmatic way, is there someone who can give me some suggestions to select the above objects?
I do not want to use nentsel as it is because it requires me to manually select the object.

For example: to make red all lines that make up a block, how can I select these lines?

with entnext I only see the attributes of the block in practice.

Thank you, every suggestion is accepted. :smile:

...with entnext I only see the attributes of the block in practice.

Who said that?

entnext can find vertex, seqend, line, text, circle, vert, etc.

Like gp told you, you're gonna swipe with entnext all the subentities of the block.
put a condition that intercepts the lines, a thing of the type (if (= (cdr (assoc '0 entities)) "line") .....)and then choose how to intervene
