As Steven P said, your arcs in order to keep the same display or look should be converted to ellipses or splines, because they are in 3d and to be displayed in 2d should be converted because they're not plain sections of circles as an arc in 2d is meant to be, that's why most of the codes don't apply to what you want

I'm sure I did because I tried exploding an object. But it didn't fill. There must be an error somewhere, but I couldn't find it, so I tried another method. Also, I'm a new programmer and I started writing lips without knowing anything about ACAD, so it was extra difficult. I'm glad this forum exists :)))

You haven't defined "arrowAng" variable and you are using it in (polar) function... Sorry, my mistake - you defined it firstly... [EDIT : You should changle variable "angle" to something different like "ang" as (angle) is AutoLISP function and then you should localize "ang" in main (defun) instead of "angle"...]

I found it making a google research is at: https://sites.google.com/site/cadkits/home/chz20 And I don't know if this is of some help

There is a CHZ20.vlx around somewhere, I do not recall everything it does or how fast it would be. What exactly is the time on a basic drawing? As mentioned, cannot really tell any specific issues without the full LISP. I have noticed FLATTEN actually can take a long time on a drawing with lots of objects, even if it is completely z=0 already. FLATTEN and FLATSHOT are mostly useless, IMHO. I would start with just a simple z=0 LISP, then run different LISPs to specifically target other objects like Regions and Blocks. I am not sure if the arc issue have ever been solved, you may have to look around and see. Can you post a sample drawing?

That's strange, in my testing it works as I expected. Are you able to post a sample drawing with an arc that rotates? Going to look at the other object types sometime today for you. There is a list at the top of 'Flatten Lines' that work at the moment for info.

Just a out there way to get centroid, if you have a open pline then close it, use "Extrude" a height of say 10, then use "Massprop". Centroid: X= 0.388 Y= -3.101 Z= 5 Ok so choose the write to file option and read the centroid from the file, the sixth line. If you want the pline open then do a UNDO. Yes it will be a lisp, have used the write to file for concrete Tilt panels to mark the centroid.

arcs in this case will need to be converted to ellipses to display properly.. something to think about
