Help: Importing File from Solidworks 2008 into Visual Nastran4D

[kevin08]

Hi,

I'm trying to import a solidworks file to Visual Nastran4D. I have a part and assembly file of the 3d model designed in SW2008. There are many ways to import a file to visual Nastran 4d like IGES, STEP files. The IGES file convert the assembly model to single part. And STEP file converts model to individual part. In STEP file converting from Solidworks it lost all the constraints.

I tried to save my assembly file into a step and IGES file but there is no step or IGES file to be found. Why is that?

I tried to import the assembly file directly to visual Nastran 4D but this doesn't work. I print screen the error I received in Nastran 4D. (see attachment)

I tried a Parasolid file and I lost some of the components when imported into Nastran 4D. Why is that?

I need to try a step file and IGES.

I attached the error message I recieve when I import the Parasolid file into Nastran 4D.

STP and IGES files do not understand constraints. They describe part geometry only.

I have not used Nastran4D, but in a similar product for mechanisms analysis I would import each part as an stp file, and associate that part with a massless rigid body that already has the constraints applied.

kevin08,
This sounds like a Nastran problem rather than SoildWorks.
Try forum825

Hi.

I posted this message in Nastran software general discussion but no one has posted a solution to my problem. Can anyone help me?

Thanks,
Kevin

Can I be missing some parts when I import the Solidworks file into Nastran because those parts are too detailed or the part is not created correctly?

Sure it's true. I saw it on the internet.
