Needing to see a an angle of 20 degrees I made the following right angled triangle. Vertex of interest on the right. The angle is close 20 so i have added an angled guideline, 160 degree should coincide with leg of vertex.
My idea was to edit in properties, the guide line angle to 160.00 but that does no work properly seems to be an offset.
Also in properties angle is 159.xxx but when I hover the mouse over the guide line it is 113.90
Then I was going to add a note with the Version number but I think all the options for adding a note has a 'hangup'. An option can be selected but the when ok clicked and crosshair location clicked the mouse loses contact with the crosshair.
Any suggestions? Am I the only one with the problem.
