I repaired my permissions and the z88aurora started working. However, my difficulties continue. I cannot import my step files. I have a simple 3D-model made by using the formZ 3D modeler. It can export in IGES, STEP, DXF and STL formats.
Two types failure reports appear in trying to import STEP files:
1)..."sh: -c: line 0: syntax error near unexpected token `(' "
2) "sh: /z88GeoCon: No such file or directory
usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file
cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory
Start des CAD-Konverters z88GeoCon ...
(z88aurora:916): Gtk-WARNING **: Unable to find default local directory monitor type"
Well, I am a beginner in X11 and everything looks and feels a lot more difficult than Mac OSX GUI.
