How we get the best performance?

Hi onshape comunity,

we develop a big CAD Modell.

And we get always performance problems when the model get bigger and at the end we have very slowly and instable CAD Models. Because we use fdm printing machines, the model is represented on a few parts with hundreds of features (650 feature).

Also to use all in one document is a problem, because also small partstudios begin very slowly now. If we move in other documents we lost the history. Start in new document and insert the former modell as derived part is the only way to move forward???

How about the hardware? we use a I7 Laptop with 32 GB, raid SSD and special 3D Graphics with heatpipe. But we dont see oneshape use the availble resources. Our internet is 100 Mbit syncronus line.

What we see is, that when the browser use more then 2.5 Gbyte, onshape get trouble with perfomance and stability. Our Models need now 6.5 Gbyte in the browser and we can´t go forward now.

    650 features is a lot. Can you share the URL of the document? Maybe we can suggest a better method.

    A couple of things we have figured out:

    Geometries imported with step or parasolids don't instance geometry in an assembly.
    You have to instance common geometry in an assembly for performance.
    With assembly patterns, we change the display quality to coarse in the part studio.
    Break your assembly up so you're not working in the entire thing all the time.


    We're getting pretty good performance,

    @Yakolev - Another thing you might try (if you haven't yet) is going to https://cad.onshape.com/check to make sure Onshape is using your graphics card appropriately.
