Hi!
I love BezierSpline - thanks! - but is there any plugin that can make a "C" curve out of a vertical "A" and a horisontal "B"(see attached pic)?
Mikael

You can try Curviloft Loft By Spline, just keeping the contours

Fredo

Thanks for suggesting.
Tried it, but since I wanted to create the "C" curve, I tried w/o it, which didn't give the desired result.
What I want is to NOT have to create two groups/components, and run th command "Intersect faces" to create a 3rd "C" contour.
Is that possible?

Hi! Is there any chance to override the maximum segments (300s) for each bezier curve made?

I am not sure that curves should have too many segments , as a general statement.
But, I will increase it to 600 in a next release.

In the meantime, you can edit the file bezierspline_main.rb, line #62 and set the value you wish.

Great! I'm doing some experiments with SU and 3D printing, that's why.
I agree that many segments slows down at least the next phase with Curviloft.
Maybe have a warning at a specific amount of segments with "don't show this message again" option.

Select the 300s curve, right-click/Explode, right-click/Convert to Catmull spline = 1800s.

What will the difference be between the 2 options?

That's not the same curve, but visually, with hundreds of points, they may look the same!

Please update BezierSpline signature for compatibility with SU 2017

Great plugin !!!
Btw can you do B-spline through points like this one :

In BezierSpline, you have several tools to have the curve go thorugh the control points: Cubic BSpline, Catmull, FSpline.

I tried these tools but I feel that not what I needed.
The begin and the end of the curves look too flat.
F Spline is better but still flat.

I included an image here :

The curve which generated by the B Spline through points look smoother, but that plugin is hard to use and lack of editing tools.
So I hope you can add that to yours.

Fredo doesn't need to add editing tools to this extension. You can already edit the curves created with it.

No, I mean that I hope he can add that type of curve to his plugin !!

I have some trouble when editing the curves.

I drew a curve in Side view

The I switch to Top view to edit control points

But when I back to Side view, the curve changed a lot !!

So, how can I move the control points along a specified axis (X, Y, Z)?

Thanks.

Dave R

If you want to keep the curve in 2D, it's best if you start out by drawing it on a large rectangle. Or, you can set the camera to Parallel Projection and selected the appropriate standard view befor editing the curve. I like the large face option myself.

Or use the plugin WorkPlane.

I am using v1.9 with Sketchup Make 2017 on a Mac. Some of the curves do not allow me to edit them after being created. After selecting the curve, with a right-click I get the standard menu items and not the editing options. Some curves work and some don't. I've seen this with the Cubic Bezier Curve and Catmull Spline. It appears to have something to do with the number of control points. Simple curves and its OK. Curves with more control points and I loose the edit function. Any suggestions?
