Had this error when I tried to save a HATCH in a drawing. I'd imported from some website somewhere.
Not my file so can't reproduce it here but will point to it's web page:
trying to save legno1.pat hatch with a scale of 300 and an angle 90 degrees.
I stuck the file in qcad/patterns/metric
can anyone reproduce this?
perhaps the pattern files are not quite compatible?
Thanks for your help.
RC5 is looking very good.
Sketchup 7 allows me to import dxf's produced with dxf version 2000
which is a boon.
