Sculpt surface tangent control

Anonymous

Hi!

I'm working on Fusion 360 and for the first time using the Sculpt environment. It's fun being used to SW and Rhino.

I'm having this issue with the T-splines, the line between them seems to be double curved and I'd like it to be smooth, see pictures below. Is there a way to access the handles for T-spline curves like in Rhino? Or is there a way to make these curves single-curved?
I'd be grateful of any help!

Look at your T-Spline in box view mode and manually align vertices

Thank you for the suggestion. While aligning the vertices make the sufface flatter it didnt help with the curvature. Is it because it's around a star point?
Any idea of how these are best taken care of? Is there a better way of modelling round organic shapes?

That depends on what you consider as "better". T-Splines are G2 curvature continuous except at star points where they are only G1 (tangent). Thus it is advisable to move star points in the flatter parts of the geometry.

 

You might want to set the quality of the zebra stripe analysis to high and the detail level control of the body/component to fixed/high.

Judging the surface quality by the zebra stripes alone is not a good approach. Also use the curvature map and the  curvature comb.

 

In the end you'll have to have to judge if the effort you are putting into creating the perfect surface is matched with what you are able to manufacture and with what precision it can be manufactured and whether it will be a glossy, or textured surface etc.
