FlipFace (for faces) is available on the Download page. For polylines you can use the REVERSE command in AutoCAD.]]> Wed, 01 Feb 2017 12:00:37 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=12200&PID=34248&title=flipface-needed#34248 <![CDATA[FlipFace needed : Hi,I would like to know if does...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=12200&PID=34246&title=flipface-needed#34246 Author: opacheco

Hi,

I would like to know if does exit a similar LISP routine to Flipface.lsp but for Polylines and 3Dpolylines in order to flip its contour direction(clokwise to counter clockwise and viseversa ???....I am drawing for a auditorium Acoustic Design but when I use MIRROR command in AutoCad 2015, this change the initial direction of the curve using polyline: this is a serious problem in the acoustics software that I use for.

I can do this one by one in the Acoustic app but there are many surfaces (closed curves defined by 2D polylines and 3Dpolylinee only!), 8,000 aprox.!....and I am searching for a LSP routine in order to do ALL this work at once!!.

Any comments will be appreciate!

opacheco.
