Cannot Purge Linetypes

Perhaps the process of converting down gets rid of a lot, especially AEC objects

Well, I had to step away from this for a day to gather my senses. I revisited it today and made some progress in that I was able to use DXFOUT > DXFIN > PURGE. The whole purpose of this thread was to find out a way to write a script for this procedure. I almost got it to work, but it seems I you cannot script the entire process because DXFIN opens the newly created .dxf file thus "breaking" the script started in the .dwg.

I will consider this script solved and start a new one more directly related to scripting. How do you mark a thread solved?

Thanks for everyone's help!

There is no way currently to mark a thread as solved.

If you want to start a new thread regarding script writing then go right ahead.

you can do it in two batch steps. DXFOUT your files fist step then second open DXF and purge then save. Using something like multibatch you can automate this

If you DXFOUT the drawing then open the DXF file with a text editor.

Search and replace one of the errant linetypes e.g. { -E- }

Start with a blank drawing then DXFIN and purge a couple of times.  First some blocks go then the unused linetypes.
