Bad import STP file with creo 8

[DD_10550851]

I am using Creo Parametric Release 8.0 and Datecode8.0.12.0

When i import the STP model in creo 8 , a receipt a surface instead of 3D model . When i try the same thing with fusion 360 and spaceclaim i receipt a 3D file .
I think that it's due to a adjustment in creo . need help

Here are the errors that I faced
no error

You are asking why when you are importing a STEP file into Creo it does not make solid geometry from the import feature? This happens with some files, and it can be caused by many things.  Post the STEP file here (put it in a zip file) so we can review the data and results of the import.

If you want a quick fix, open the STEP in Spaceclaim and then export it is a solid STEP and try importing this into Creo, it may resolve the problem.

If you want to learn how to deal with this inside Creo then start by reading this article.

It could be as simple as an accuracy problem; you could try using the external accuracy setting on import (see above article).

Thank for your help , sorry but the 3D file can't be shared ... but i'm going to check the link you gave me.

There are a few things you can do to possibly improve the results. 

During the import, select Details.

• On the Model tab, set Model Accuracy to External (If you know the accuracy of the original model, set your model accuracy to that before importing)
• On the Topology tab, I always start with:
  • Join surfaces from different layers - No
  • Join surfaces from the same layer - Yes
  • Solidify closed volumes - Yes
  • Close gaps between surfaces - unchecked
  • Repair unsatisfied geometry - unchecked

The model accuracy, I feel is the most important.  The math between different accuracies rarely works well.  You can turn on the repair options but understand that surfaces will be changed.

Thanks for your help , 

I agree with you about the model accuracy , but unfortunatly , it comes without this information . 

Regarding the options i'm going to try .

In addition to what kdirth said, I also uncheck all options on the surface tab (G2 fix, simplify surfaces, etc).

I want the STP file to come in with as little modifications as possible. 

In my experience, the automatic fixes make things worse 99.999% of the time.

Thanks Aputman ,

i'm going to check the options in order to see if it's better with or without  these options.

Best regards
