With their feedback we will add material to the model to make a configuration for the cast version. Our goal is to develop a solid file that represents the part we scanned and then to use it as a starting point to talk with sand cast vendors. Probably not all the surfaces were machined or hand-worked, but certainly some were. The part that was scanned is from a surviving aircraft so it had been finished. I suspect the only viable option for making it at the time was by sand casting.
This part was made in the early 1940's for a B-17. If we had the drawings all would be made clear. The folks working on this aircraft rebuilding project are all over the country. I do not know all the specifics of the origins of the part and I have not seen it in person. Was this originally a sand cast aluminum part, or how was it made? Those software can't convert it to NURBS, the STL mesh will be more like a reference 3D image while creating sketches/features in SolidWorks. You could also fix and decimate the mesh in a specialized STL mesh editor or a 3D computer graphics software (Blender, ZBrush, 3DS Max, Maya), lowering the amount of data makes it better to import in SolidWorks.
Rhino7 has QuadRemesh as an affordable option. I don't know Onshape tools, but sounds like you saved the Mesh Data inside a Step, you need to convert the mesh to NURBS so you can use it as surfaces.įor that you will need a Reverse Engineer software, like Geomatic DesignX, PolyWorks Modeler etc. We have some discussion about it here: viewtopic.php?t=1264 We do not have drawings for it, apparently they don't exist (according to the professional historian leading this project - and he's found just about everything else!) Our objective is to eventually get a casting of this part. If we can get this STL converted to surfaces or something we can reference then we can repair the holes and make a complete solid. I was able to open a smaller scan with similar holes in Onshape and saved it out as STEP, Parasolid, ACIS, Object, and IGES formats, but if they opened in SWX they were still the unusable mesh surfaces.
Since we can open the file in Chitubox slicer software rather easily (it even slices it despite the holes in the scan) is there a slicer program that can convert (Save As or Export) to a usable file format? Is there a SWX add-in that can do the job? I have no experience doing surfacing so this seems intimidating. Does anyone know if SWX 2022 has more capabilities to deal with STL files? I have not bothered to install 2022 yet, but will if it can give me something usable.
