Question about imported IGES file from Materialise Mimics software

Jane Li Jul 31, 2018 3:19 PM

Hello All,

I was trying to use solidworks edit an imported IGES file which I exported from Materialise Mimics.

The original model was scanned by Micro-CT scan and I have imported all the scanned image into Mimics to generated a 3D model by applying the right grey value. After that I exported the model in Mimics as IGES file. However, when I opened the IGES file in Solidworks, the model looks weird, it is a structure which made up with imported curves, like this:

The green part (sweep 1) is what I made according to the imported curves, but this is not a good solution for me because I need to get this part assembled later and I have to keep the geometry as original as possible for the future FEM results.

So my question is: did I imported the IGES file correctly? or Do you have any suggestions for my problem?

Thank you very much for the help!

It could be export setting on the other software.
Can you export in other format? Parasolid is best because SolidWorks is native Parasolid. STEP and last STL.
Try to make sure it export solid or surface or mesh.

  Hello Frederick,
  Thank you very much for your reply.
  Yes, I have tried to export the model as STL file before from Mimics, the problem is that the model I have generated in Mimics is only a half from my original scanned model. The reason I only generated half of the original model is because the computer can not handle all the scanned images which I have imported into Mimics, I have waited 24 hours and it can not give me the whole 3D model as the result.
  
  Also, I need to do FEM based on the whole model, but STL file can not be edited or assembled in Solidworks since it is a mesh file not a solid model.
  I have tried to use Rhino to turn the STL file into solid model, but because the STL file has 28108428 polygons, so it did not work out. After that I have tried to reduce the mesh in Rhino but reduce the mesh will make some mesh surfaces disappear and I don't know how to fix it, like this:
  Here is an image from the control plane or Mimics software, it shows which file type that Mimics can export:
  If you have more suggestions please let me know.
  Thank you very much.

Hello,

According to this page: Data prep STL-based tools: import | Materialise - Innovators you can count on , IGES isn't listed as an export format.
Where did the file originate from?

Cheers,

Kevin

  Hello Kevin,
  
  Thank you very much for the reply.
  I am sure that this IGES files was exported from Mimics software, here is a picture I took from the Mimics control plane:
  As you can see the IGES file type is an option for them. I think it could also be a good idea to ask Mimics webpage, maybe they could also help?
  
  If you have more suggestions for this problem, please let me know.
  Thank you very much.
