Salomè unit .step file inport unit problem

Posted by Jacopo at February 29. 2012

Hi to all developers,

Salomè from the version 5 and later continue to have problem to recognize the mm unit from .step file ( in version 4 this problem do not appear).

Salomè work in meters so when you import a file with unit in mm the dimension appear 1000 time lower. For the FEM analysis this isn't a problem because the FEM haven't unit is important that you will be coherent with the units; but if you use Salomè and Aster for real industrial application where all the units are in mm this is a problem. To solve this problem you can go in .step file open with text editor and do it:

 

SI_UNIT( .MILLI., .METRE. ) --> SI_UNIT( .METRE., .METRE. )

 

so you must replace in all the file the part where you show MILLI in METRE. In this way the problem will be solved.

But is it possible to solve directly this problem in Salomè? Why in version 4 this problem there wasn't and now appear?

 

Best Regards

Jacopo

Hello,

I have seen the same behavior, but didn't find such a nice work around as you: I scaled the mesh before export ! Thank-you for this. Indeed annoying, hope it will be fixed soon.

Have fun !

Michael
