All of these features are available to ensure your geometry import process is painless. Second, for ensuring the imported geometry is ready for analysis, you can repair, defeature, or apply virtual geometry operations to your geometry to fix discrepancies during import or to simplify the geometry. First, for importing geometries created in CAD software, the CAD Import Module supports the import of a variety of different file formats, including the Parasolid ® and ACIS ® formats, standard formats like STEP and IGES, and native file formats of various CAD systems. I’ll let you know what they say about it.The CAD Import Module add-on to COMSOL Multiphysics ® has two basic functions for assisting your modeling workflow. Maybe a 2D flat (unfolded) layout will suffice. However, it’s still basically a flat part that’s cut and bent. It’s been 25 years since I did any sheet metal design and times have changed (a lot). I sent this drawing off to Xometry to ask them what’s the best way to present your request:
I played around with the sheet metal workbench in FreeCad, but it only does bends that are at right angles to everything else. Like any manufacturing process, there are limitations and trade-offs. If you haven’t already, you should download their sheet metal guide. This is a little more difficult, but it seems like something that shouldn’t have to be spelled out. This is simple enough to do, but the bends where the cut metal is angled results in a helical surface along the edge as it wraps around the bend. I created an outline of the “el” and then used the Push/Pull tool to extrude it. How did you make the bend in your example It’s somewhat depressing to see that folks are still using Hollerith ASCII format ( I had to reverse the sense of the vectors during the import. When I’d see a radiused part that looked like this: Most of the issues revolved around inconsistencies between various exporters, notably defining the normal vector to an arc … most exporters used the right-hand rule and some, for whatever reason, used the left-hand rule. Side note: From about 1982-1990 I wrote a number of IGES importers in FORTRAN for GE Calma systems. I’m not familiar with STEP files, but I’ll look into its format when I get a chance. I suspect that any SketchUp STL export of lines and faces will translate into the same IGES entity types with no problems. There are twelve of these sequences … one for each triangle in the model. I’m not sure about the STEP file format, but the IGES format exported by FreeCAD outputs planes (144 - Trimmed Parametric Surface) bounded by (142 - Curve on a Parametric Surface) lines (110 - Line) for the case of the brick.
