I have a viewport with a plan view rotated with a UCS. I have another viewport with my cross sections in WCS. While adjusting the alignment, while still in the UCS, the labels for the cross sections rotated based on the difference in angle from UCS and WCS. When I reset the plan to WCS, the cross section labels return to normal (after a regenall). Is there a toggle to keep the section labels from becoming "plan-readable"?
In the Label Style Composer, on the "General" tab, try the "Plan Readable
Text" setting. For other effects, you can change how the angle is
interpreted by setting the "Orientation Reference" to Object, WCS or View.
