betti cad mesh

Mesh a STEP file watertight, each triangle tagged with its CAD face.

cad module Granted on request: see access and licensing.

Usage

betti cad mesh [flags] in.step out

Examples

betti cad mesh part.step part.3mf
betti cad mesh part.step part.obj -chord 0.05 -angle 15
betti cad mesh part.step part.vtu -size 2
betti cad mesh part.step part.vtu -groups bodies
betti cad mesh part.step part.obj -size 1% -quads

Flags

Flag	Takes	Default	Meaning
-adaptive	switch	off	with `-size`: smaller triangles where the surface curves
-angle	number	none	most the surface may turn across a triangle, in degrees (0: 20)
-chord	number	none	most a triangle may stray from its surface, in mm (0: a thousandth of the model's size)
-groups	text	`faces`	tag triangles by their CAD faces or their bodies: faces\|bodies
-quads	switch	off	with `-size`: quads of about that edge length on the exact surfaces, conformal across CAD edges (OBJ, OFF, PLY, VTU and MSH keep them; 3MF holds triangles)
-size	length or number	`no remeshing`	remesh into well-shaped triangles of about this edge length, such as 2 or 1%

Output flags

Flag	Takes	Default	Meaning
-json	switch	off	print the result as JSON
-q	switch	off	print nothing but errors
-v	switch	off	also show the stages of each step, and their times
