Core Free
| info | what a mesh is: size, parts, holes, crossings, element quality |
|---|---|
| box | the smallest box in any orientation holding a part, as for stock, packing and shipping |
| verify | check a result against its input: distances, faces' turn, sharp edges, topology |
| convert | convert between formats, repairing connectivity on the way |
| run | run steps one after another on a mesh kept in memory |
Fix On request
| fix repair | orient parts outward, fill holes and remove self-intersections |
|---|---|
| fix orient | turn parts over so that their faces show their front to the outside |
| fix shell | keep only the outermost surface, nothing inside it |
| fix denoise | remove noise, as from a scan, keeping sharp edges |
| fix wrap | wrap any input in a closed, valid surface just outside it |
| fix reconstruct | rebuild a mesh broken throughout from samples of its outside |
Mesh On request
| mesh remesh | remesh into even triangles, or quads |
|---|---|
| mesh assemble | mesh touching solids so they conform across interfaces |
| mesh midsurface | the mid-surface of thin walls, with their thickness, for shell elements |
| mesh centreline | the centrelines of slender members, with their sections, for beam elements |
Shape On request
| shape cut | cut a solid by a plane into two closed solids |
|---|---|
| shape boolean | combine two solids |
| shape offset | the surface at a distance outside or inside a solid |
| shape hollow | hollow a solid out to a shell, with drain holes |
| shape defeature | remove small holes, pockets, bosses and text |
| shape decompose | split a solid into convex hulls, as for collision detection |
CAD On request
| cad check | find what is wrong with a STEP file: gaps, open shells, faces turned over, short edges |
|---|---|
| cad heal | repair a STEP file, CAD to CAD: faces written apart sewn into closed shells |
| cad mesh | mesh a STEP file watertight, each triangle tagged with its CAD face |
| cad primitives | the planes, cylinders, cones, spheres and tori a part's faces lie on, with their sizes |
Additive manufacturing On request
| additive place | turn a part to print with the least support, and set it on the bed |
|---|---|
| additive slice | cut a part into layers for printing: outlines as SVG, images as PNG, or 3MF slices |
| additive thickness | measure wall thickness and find thin walls |
Particles On request
| particles fill | fill a solid with particles, or line its surface, for SPH and other particle methods |
|---|---|
| particles clump | approximate a solid by overlapping spheres of varying size, for DEM |
| particles spheres | fill a container with spheres of given sizes, touching neither each other nor the walls, for a DEM packed bed |
