Hi,
I would like to add points on a circle in order to deform the shape.
A kind of wave on the front of the shape. I can do it with Moi3d (screenshot gray ) but i don’t find precise information for Shapr3d. (what I want on the black Shapr screenshot).
Thanks a lot.

The spline tool in control mode is what you are looking for.

Thanks PEC
OK for spline and arc tool but is it possible on a circle ?
For an “editable” circle, you can create a control spline with control points placed at the vertices of a regular hexagone. You will get a perfect circle and then, you can move the control points to alter the shape.

Excellent ! Thanks a lot.

I tried to draw in a square, I aligned the points to the midpoints of the sides of the square with the midpoint constraint. After fitting a circle on it, I found that it was not regular. My be too less point…
just to understand the circles drawn by the spline, I made one in hexagon and dodecahedron. The result is more and more accurate the more points we draw.

Bravo JST !
My mistake, @JST you are right for hexagon.
Actually to get a perfect circle, you should use a regular octogone or any regular polygon with a multiple of 8 vertices.

OK well noted !
if we want to be even more precise, the more vertices, and by drawing a circle larger than the desired one, and then reducing the “radius”, we get an even more accurate result… good to know…

Otherwise, if we’re talking about splines. Is there an app for iPad where I can draw splines from .dat files? I would need profiles of ~300 points. It slows down my projects a lot that I have to ask others to draw it for me (usually this is done in rhino), then they draw it out as a template rib, and I usually import this in step and projectele to get a spline here…
I ask the pros.
How i can move separately the points as my screenshot above ?
Thanks
It would be a 3d spline, I don’t know if this is possible… but you can create the surface with the subtract command…
Yes you are right 
I tend to want to make it complicated.
What is the simplest way to do this with the subtract command ?
Thanks a lot !
Oups It’s a shame.
Yes it’s better than Points
Thanks again.
