Polyworks 3D scan to CAD

cheesiechanman
Hey guys. Have you all used a 3d scanner to create cad files? We have a romer arm with polyworks. We would like to scan some end of arm tools here and convert the pointcloud into a useable CAD file that we can 3D print.

Have you all done anything like this and how did it turn out? any advice? software suggestions? Tips and Tricks? Is it worth the time and effort?

We spend 4k on each of the parts we want to replace and this method could potentially save us tons of money.

    My new job that I am starting in a week has a Romer arm with polyworks. I dont know much about polyworks so I am excited to play around with it but I will definitely need some advice.

    Also, there may be another forum not on this site that is better for Polyworks questions.
  • It depends on your 3D printer...
    The easiest way is the .stl (mesh), that you can enhance (filter, delete holes...).
    You can also transform the stl in a IGES, then import the IGES to save as a step, or create nurbs, patch nurbs, and step from them... It's long, not really easy or intuitive., and can give very large files...
  • What said. Converting the cloud into an STL should be enough to make it printable.

    If you have the MESH option in PC-DMIS, I think you can create an STL from your pointcloud.
    Other than that, there are free solutions to convert into STL as well.
  • Do you have polyworks inspector or modeler? I think modeler (I don't have) would help in the creation of cad files. I have inspector. You can scan a part to create a mesh however it doesn't know what features are in the mesh. You have to tell it these points are a plane, cylinder, cone, etc...Then you can use I think grow and trim options or something like that, export as a polygonal model, import into solidworks and then trim edges, then you can create an actual cad file like .iges or step. There is a youtube video out there showing this in more detail. Very cool stuff.

  • If you have the polyworks metrology suite the modeler comes with it. You don't need any other software for conversions, or feature creations for that matter. The software will take care of it all. Just as well, you can save or export your files into igs or stp formats.
  • I do this type of thing regularly at work. It does work well with modeler, but it takes a long time to make effective stp files from the point clouds.

    This does depend on the size and types of features you're looking to capture. If it is a smaller part 3" x 3" x 3" with limited freeform surfaces then it would take a couple hours to develop a good solid model.

    For things such as an oil pan with more freeform surfaces, it usually takes 8 hours or so.

    Solidworks used side by side with Polyworks has been beneficial when needing to edit features or fixing small things with the model
  • Got REcreate (from Hexagon) but haven't had time to sit down with it yet. FARO has their RevEng and Zeiss their own as well.

    I was planning on getting an add on for solidworks called Rhino i believe. Its a one time payment rather than an annual subscription like modeler. and apparently it is pretty user friendly.

    All of our scans will be pretty complex.

    The solidworks portion is definitely beneficial and like you said about it having a one time payment helps reduce cost. I still am learning more about solidworks every time I use it so I know there is a lot more to it than what I'm capable of so far

    Whats the price tag look like on REcreate? and when you get more familiar with it drop back by this thread and let us know how it works if you dont mind.
