Sections of Position and Size dialog grayed out

When a Calc chart or a Draw rectangle is selected, right-clicking on them can open a Position and Size dialog. On the Slant and Corner Radius page of that dialog, the Corner Radius, Control Point 1, and Control Point 2 sections are all grayed out.

Is there a way to get the grayed out sections activated or are these bugs that should be reported (I could not find bugs reports for them).

Also, what are Control Point 1 and Control Point 2 supposed to do?

I too would be very interested in an answer to this question.
I selected a rectangle but the Corner Radius is still greyed out.
Also tried a rounded rectangle.
Perhaps one of Administrators would care to comment.

Depends on the kind of object. Control points are used with some AutoShape objects, like the pie or triangle object. Not sure where corner radius comes into play, I would had thought rectangle but apparently it’s not, not even with the rounded rectangle.

Your answer seems to agree that Corner Radius remains greyed out even when a rectangle is selected. So, does this mean there is a bug?

I’d call it a usability bug, see also that question.

Thank you for your response. I looked at ‘that question’ and found the answer provided by Regina very helpful. Being new to LO Draw, I had not realised that there was a toolbar for Legacy Rectangles.
I think that your description “usability bug” is very apt.
