IGS / STEP export/import parameters

[0502880]

Hi,

could someone give some advise which IGS and/or STEP parameters will work best when trying to import a file from different CAD system? We have tried to export a (complex) file from Delcam PowerShape and import it to Fusion, but I haven't managed to open it as "watertight" in Fusion. Or is STL mesh only possibility to get it as watertight model to Fusion?

Thank's!

Hi @0502880

Thank you for posting your question in the Forum.

I know it is tricky to import files from one CAD system into another without any issues.

From experience I would suggest to export a *.step and repair it in Fusion

There might be an easy fix to create a watertight model once you import your step file:

1. Just go into the "Patch" environment
2. Select all faces and edges and use the "Unstitch" feature 
3. Than, select all faces and edges again and use the "Stitch" feature
4. Now you can you use the "Interference" and "Validate" feature in the "Inspect" ribbon to check the quality of your design

From the sound what you have explained are you trying to create a model for 3D Printing, maybe CFD?

If you like to you can share your design and I can help you to work on it?

I hope this helps. Please, keep us updated.

Thanks,

Thank's Mike for your answer! Should try that unstitch+stitch method.

Is it so, that those Interference and Validate under Inspect menu only checks the model, there is no possibility to repair anything?

If I remember right, in many CAD programs there is a possibility to change several parameters when exporting files (not sure for Delcam). Do those parameters help anything with this "watertight" issue? Any suggested parameter settings?

I should get some small changes to be done to the imported model and after that it should be rendered (and probably 3D printed).

Sorry, I can't publish that model.

Hi @0502880,

Thank you for the update.

I know that a lot of CAD systems give you a couple options before importing a file. This would be the

"Validate" and "Interference" function which would point to the issues in the file.

You would repair your model half manual and half automatic by using "Stitch","Unstitch", "Merge" and "Split face".

I am not sure if we can trigger the surface and edge quality before exporting the step.

This could make it easier for the translator to keep the edges pasted, not disconnected.

Could you may share a screenshot about the output options?

If you just like to 3D print your design, you could just use the *.stl and work in our new "Mesh" environment.

I hope this helps. Please, keep us updated.

Thanks,
