T-spline model wont thicken

jona.nolakers — Tue, 25 Apr 2023 16:02:01 GMT

Halo!

I have made it work by thickening in t-spline editing, which caused a lot of self intersecting surfaces. It worked after fixing those, but now the company that will be prining the model says they need it 0.1 mm thicker. This is where it would be beneficial if I was able to thicken it in brep modelling, which works, up to 0.0001 mm thickness, not the 0.7 mm I need.

Any information on what causes this, or what I can do to make this work apprecuated.

With kide regards

Hi,

Without an analysis of the construction we can not give any hints.

If thickening in the T-Spline workspace cause self intersections, chances are that the same happens in the BRep environment.

Very nice model!

This isn't ever going to thicken in BRep mode.

The best way forward is to thicken in T-Spline mode, simplify and remove self intersections, so you are left with smooth surfaces without small radii and creases on the inside. That will make it easier to add some thinckness later.

what is the reason for this? Just curious for future projects.

Offsetting surfaces creates self intersecting surfaces when radii are smaller than the distance you want to offset or thicken.

is there a way to avoid radii smaller than, in this case, 0.7 mm?

Model differently ?
