How can I get the outline of "Insert entity" ?

[kenjung0730]

Hi, all:

 

I have a trouble with dealing Insert entity.

I got a "Block" named "AA", which have one "lwpolyline" entities inside.

And then I insert it with "scaling & rotating".

 

The problem is, if I want to get the current outline of "Insert".

My process is as below.

 

1. get "Block entity" from "Insert entity"

2. get "lwpolyline" from "Block entity"

3. transform the "lwpolyline" by vla-transformby(...) function with "Insert entity" rotation, scale ... parameters

4. draw the renewed "lwpolyline" on drawing as outline

 

It works, but I think it cost a lot of times.

Is there any convenient way to do this? thanks!
