Control Points Bezier Curves

MLUY · 6 Jan 2023, 12:28

Does anybody know how to get the co-ordinates of the control points of a Bezier curve?
I am using Fredo6 BZ_Toolbar and I have been unable to figure it out
Any help / tips appreciated, perhaps I need another plugin (which?) but I really like this one

Thanks!

Usually I approach it from the other direction and create identifiable location for the control points of the Bezier curve. Would that be possible in your case?

Are you still using SketchUp 2015 Make as your profile indicates?

One possibility is to convert the original to Polyline, which will give you the sequence of control points. Indeed, make a copy of the original bezier curve before.

Thanks Dave!
That would not work in my case as I want to trace a shape (imported image) and then I trying to adjust set the control points to get the shape I need

wow, I am honoured to get a response from the great Frodo himself!, you are a absolute hero just wanted to say that.

But I am not quite sure what you mean, because if I convert the bezier curve to a polyline (which I did) I just get a polyline....where are the control points ?
