Hello everybody! I wrote a program that reads in AutoCAD DXF (R14) files, and it doesn't have a problem as long as the extrusion is the default (0, 0, 1), it simply doesn't care at all about it. But c. 10% of the entities it has to read does not have the default extrusion, but for example 0, -0.559, 0.829. The start point of a line (10, 20, 30-groups) is given with 17000, 72000, -50000, but should be something like 17000, 80000, 0. I didn't find any usefull documentation, so here's the question: How do I calculate the right coordinate with a given non-default extrusion? thanks. --Daniel Daniel Cermak-Sassenrath dace@informatik.uni-bremen.de University of Bremen, FRG
