Importing large step files

[csteven_e91]

I would like to know the preferred method for importing extremely large .stp files. We are attempting to import an entire vehicle that we've received as a large group of step files. I simply need this geometry as reference only. The components we design will be new part files that will interface with some of the imported geometry, hence the need for the imported files to be reference. We do not intend to modify any of the imported geometry, but we do wish to delete some as the design evolves.

Our current process of importing files into an assembly has take more than a week using 3 separate computers. There has to be a more efficient way?

An entire car is a crap ton of data.
Step is a "neutral" format that requires real conversion time.
If it came out of a parasolid based system your way better off getting a parasolid file to import. It would be much faster.

Once it's in you could create the part files needed to manage it better or maybe use layering to control visibility.

That's all I've got.

Yeah, it's a lot of data for a full size van. For the next set of files, we will request parasolids. Thanks for your advice.

As far as using the data as reference for our design phase, what is the best method? I envision each of our designers to work out of their own layout. Their layout would have the OEM vehicle as reference. Ideally, this is one "dummy" solid file at the beginning of their layout assembly model tree. They could turn it on and off when needed.

Thanks for your help!

Instead of importing it Using NX, you might be faster using the "External" Translators. You can find them in your installation folder (start menu)

I would "batch" translate them as Ronald suggested. You'll have to set the variables manually to your Java folder.
do a small batch 1st and make sure you are getting the results you want, adjust settings as needed and then do the rest overnight.

Your management method sounds fine.
If you have multiple users working with it they likely only need to see what rubs up against what they are responsible for.

You can use reference sets to help keep the graphics lighter for your users.
Give each user an assigned prefix when creating and naming their own reference sets... or something like that.
