Offset lines in Assembly Drawing

Any idea ? Thanks a lot in advance Pier

Couple of thoughts a.. The color changed to brownish pink; go into 'View>Display Settings>System Colors' and pick "Use Pre-Wildfire Scheme" or change your background color to make them more "contrasty". Be sure to save these settings to a syscol.scl file, put it in your startup directory and call it out in config.pro with the system_colors_file option by browsing to the file. b.. Look for a layer that might contain them and unhide it. c.. Look in the model tree where they are now listed as objects and make sure they're not hidden. d.. Edit the offset line linestyle which allows you to change the color, create a new color and reset the default line style. This is a less drastic course of action than changing all the system colors to pre-Wildfire. David Janes
