Importing models (Step, IGS) best practices.

joep

I imported a Step file into a part studio and plan to use the geometry to create tooling. The tool will consist of multiple parts. 
As in most cases with imported models the Step file is imported it is not located in the desired location i.e. origin,top,right, front etc. This in return will cause issues if I want to create a drawing. I do not want to use the "named views" as a workaround a someone else suggested in the forum. 

What is a recommended best practice?

1. In the parts studio: Add "mate connectors" and transform the imported (Step) model to the desired location and design the tooling?
2. In Assembly: Import the (Step) file and locate the model in the desired location and design the tooling in context?
3. In part studio: Use a derived part method, it uses more resources?

Any advise/insight would be appreciated.

Best Regards,

Hi @joep

I tend to use your Option 1.

Assemblies are good but depending on the complexity of your design, you may not even need one.  (I'll only go there if I need to see motion, or have many instances of the same part that don't want many copies of in a part studio.) In most cases modelling all the discrete parts together in one partstudio is a good way to go.

The contexts are great to model around things that move (say both end stops on something that slides) but may be overkill here.

Long chains of derives are bad, one or two are fine, especially from "common parts" library documents.

Shout if that doesn't make any sense!

I agree with @owen_sparks for anytime it is OK to move the part relative to 'world'.   

However, much of the time we continue to need what was discussed in this thread (something like 'update standard views' in SW  - https://forum.onshape.com/discussion/comment/23819#Comment_23819

Hmm, sounds like we want some check boxes:- "show in world/assembly view" or "show in local part view".

O.S.

Thanks guys! Option 1 it is.
