Paul.
Missed your reply yesterday but have emailed you the file this morning.
On the subject of fixed size segments, can I ask you a question on how to approach the problem in the image below.
I've rotated a vertical post to become a raked spar on a roof atrium, to fit I adjusted the fixed size, but this seems locked to the world, or the RC co-ords. Tried scale too, and the Y axis but same thing. Is there any way in Railclone to adjust the segment value locally, or should I adjust the segment itself to fit.
