I successfully created it into a solid file to be used, and I always reach the same problem. Going from Gcode to a model that you can edit is pretty difficult or impossible. Hi guys, Im a 3D Artist who was given the task of converting an STL (3D Scanned) file to STEP file. We reverse engineer an object using free software (FreeCAD & Nefabb).
Using freecad to convert from stp to stl how to#
It specifies where a tool should move so it's just a series of directives that move a tool from place to place at a given speed. We show you how to convert an STL file to a STEP file. Gcode doesn't say anything about the model itself. Search on the FreeCAD forum for posts about converting or look here: Results are usually less than spectacular but might be good enough depending on your needs. Here's a post about that:įreeCAD also has some tools to convert a mesh into a solid. You can do it in the gui in the mesh design workbench or through python. If the STL file has a size of around 1GB then the mesh must have approx. This is just the wrong way of converting from STL to STEP. That said, simple scaling of a mesh is pretty easy and can be done trivially in FreeCAD. STL file is from a 3D scan, file is just under 1GB. That's why you always want to save your designs in the native format and also in an open solid format like. Meshes are notoriously difficult to modify after the fact. Their exterior is defined by triangulated surfaces.
Using freecad to convert from stp to stl install#
Pymadcad is internally using numpy-stl to import stl files, if you need only basic manipulations you can also only install that one Transformed = union(part, icosphere(vec3(1,1,1), 3.)) # add a sphere a diameter 3 rgeclose() # merge points at the same location If you need more complex operations (such as booleans, chamfers, etc) you will need to make the triangle connected again before the desired operations. Write(transformed, 'path/to/output_file.stl')
Transformed = ansform(mat3(2)) # scale by a factor 2 (diagonal matrix of 2) So for simple transformation operations (such as scale, translation etc) from madcad import * You can use the python pymadcad module to deal with STL files Just for clarification: g-code format is just a sequence of instructions for the machines (3d-printers, etc) so it's very good for printers, but also certainly the worst format to manipulate geometry.
Which means that triangles are even not connected to each other (well they need to be adjacent to be used by software generatif g-code, but no obligation else) Well to be precise, STL files are even not meshes, but triangles soups.
