Crate geop_ops_step 

STEP (ISO 10303) exchange: reading the B-rep solids and sheets of a STEP file into a part, and writing a part’s bodies as one — so parts travel between geop and other CAD systems; and meshes read from STL.

• part21: the clear-text encoding every STEP file is written in.
• import: a file’s bodies as descriptions the kernel builds.
• export: a part’s bodies, and the parts placed in it, as a file (write_part).
• ImportStep: the operation adding a file’s bodies to a part.
• ImportStl: a mesh of triangles added to a part as a B-rep.

Modules

export

Writing a part as a STEP file (AP214, the geometry every CAD system reads): each solid a MANIFOLD_SOLID_BREP — a BREP_WITH_VOIDS if it has voids — and each sheet of faces standing on their own a SHELL_BASED_SURFACE_MODEL, with every surface and curve written exactly as the kernel holds it: a B_SPLINE_*_WITH_KNOTS, rational where a weight is not one. Lengths are millimetres: a length of one in the kernel is one millimetre.

import

Reading the bodies of a STEP file (AP203, AP214, AP242 — the B-rep geometry they share) as descriptions the kernel builds.

operation

ImportStep: add the bodies of a STEP file to the part.

part21

ISO 10303-21 (“Part 21”), the clear-text encoding every STEP file is written in: a header, then a data section of entity instances, each #id = NAME(parameters); — or, for an instance of several entity types at once, a complex instance #id = (NAME1(...) NAME2(...));.

stl

ImportStl: a mesh of triangles, from an STL file, added to the part as a B-rep — a solid where it closes, a sheet where it does not.

Functions

register

Adds what this crate offers an editor to r: importing STEP files, and writing a part as one.
