T Spline Manipulation

Hi all.

I'm not really sure what to call this, but perhaps theres a tool or a method that can help me get it right... I'm trying to get the profile of my t-spline to follow the curvature on the toe of this shoe, but the curve always seems to 'invert' itself. Sorry, I'm not able to share the file, but hopefully its clear. Any suggestions?

 

Thanks

You clearly need on more edge in the middle of these 2-points shown in the video

But remember, when adding this edge, make sure that it's a full loop and not just one edge to prevent having NGons

You should try using "Vertex" mode in Edit Form.  In this mode, Fusion shows tangent handles on outside edges, which can help you wrangle the shape with more control:

@jsmPGF5C you marked 2 replies as the solution, but really neither one addresses the root problem.

The root problem is that you are inexperienced with sub-d mesh modeling and the hurdle that presented itself to you would not be a problem for a more experienced mesh modeler.

 

As such my suggestion would be to start with a simpler model that you can actually share. You'r screenshot already indicates that the mesh is already too does an you are trying to add detail to a model before the general shape is defined and before your shoe his actually a mostly closed shape.

 

In general you should not be adding detail until you are happy with the overall shape and proportions.

Then you should very often check your model in box mode. That is the quality control for your mesh. Polygons with too high of an aspect ratio and very distorted polygons indicate that you need more polygons.

Hi @TrippyLighting.

 

Fair point, they don't offer complete solutions to the root problem, but they do offer valid workarounds given my lack of experience with t-splines. Thanks for your help and for taking the time to point me in the right direction.
