You would like only main layer locked, so you can more easily unlock the sublayers?
I ran an example, and it appears to me that Radius/Diameter works with drawings in locked layers. Can you elaborate?
These options are not the default because it takes time to create the hatch/solid and background, but they is sticky options, so once you set them, they stick.
I’ll need an example for the placement point issue.
Thanks for your feedback
I got this issue before Christmas, it maybe be solved, I saw a bug fix similar to this in the last version.
I’ll check it when I’ll be back to the office and I will answer the other two point with example.
