JimB Posted July 12, 2022 Share Posted July 12, 2022 (edited) Ive a drawing with over 21000 lines, its a dwelling. I need to flatten it to reduce size for others. Generally I explode all sometimes need to do up to 3 times, once done I can generally flatten. However this did'nt work and all stayed as a 3D drawing (viewable in perspective) So I tried 'selecting all' going to properties and reducing 'z' to zero on all lines etc. However this went I did it would not provide any options at all nothing. Is there any other option to over ride everything to reduce the drawing to 2D someone can advise me ? Ive attached a perspective of the exploded drawing that wont faltten Edited July 12, 2022 by JimB attached drawing Quote Link to comment Share on other sites More sharing options...
Cad64 Posted July 12, 2022 Share Posted July 12, 2022 Try loading and running the attached lisp routine. After loading, just type FLAT at the command prompt and it should work. Flat.lsp 1 Quote Link to comment Share on other sites More sharing options...

AVC Posted July 13, 2022 Share Posted July 13, 2022 Try A>V>C> Flat plugin. It handles any geometry well. https://sites.google.com/site/avcplugins/flat Quote Link to comment Share on other sites More sharing options...
AVC Posted July 13, 2022 Share Posted July 13, 2022 And I think you want to simplify the resulting contours, merge lines into polylines, remove duplicates, close outer contours. You can use this: https://sites.google.com/site/avcplugins/osl Quote Link to comment Share on other sites More sharing options...
Mory Posted July 15, 2022 Share Posted July 15, 2022 why not just create a 2d profile from your set view here.. its real easy and would dramatically reduce the file size.... Quote Link to comment Share on other sites More sharing options...
