Converting .STL files into .STEP files

Smasherofprobes
Hello all,

I am wondering what your companies process is for taking .STL files and converting them into .STEP files. We recently sent out a part to be scanned and received a .STL file but the designer here keeps sending me massive files 400,000 KB IGES files from the scan and my PCDMIS keeps crashing. Is there anything I can suggest to him so we can get this file made the right way? I'm not sure what the designers capabilities are but it is my understanding that the designer has to overlay the mesh file to the CAD file and actually manipulate the CAD to match the scan. I could be wrong but please guide us in the right direction. Thanks!

  • Yes, the STL is a mesh and not a CAD. With your response I'm assuming the designer has to take the mesh and create a new file from it rather than trying to convert the STL into a STEP. Could he not take current CAD model, overlay it with the STL and then make changes to the CAD so it matches the Mesh form? Thanks for your response VPT.

    This can be done, but it is a 'special' software, but I have no idea what. We use software that does this for doing 'over-bends' on sheet metal stampings. If the part is REAL bad, they have me scan it with the Romer. They take the XYZ file from the Romer, convert it to STL, then import that over the top of the tooling design, and the software does the rest, at least, that is how it has been explained to me.
