Section view of only specific parts in an assembly

GageGage Member Posts: 5 PRO
Is it possible to create a section view of only some parts in an assembly? For instance, how the cutaway view below cuts through the engine block but not the pistons, valves, crankshaft, etc.
 Image result for cutaway engine

Thanks you

    Hello,

     This functionality is not available. Can you submit an improvement request? Thank you.

    The quick and easy way to do this today is to cut the parts with a surface in the part studio. Take a look at the following example: https://cad.onshape.com/documents/5784d673e4b0b7679dc08b32/w/3475f9f1030edfb2e266e2dc/e/f6bf36675f877f268dfd5373

    Since our features can affect multiple parts simultaneously you can make the cut in just the parts you want.

    Hi Brad. The problem with this is that 

    1: Part studios generally do not contain the parts in the same quantities, location, orientation, etc. as the assembly, therefore a lot of work could be required to use your suggested method to achieved the desired result. You'd very likely need to create multiple cuts in multiple different part studios, and this would be impossible to achieve with recurring items which could be cut differently by the desired assembly section plane. 

    2: This has the potential to take an extremely long time, probably never being worth the effort. 

    Has an improvement ticket been submitted for this basic functionality mentioned almost a year ago? If not I will create one now.

    It's a bit of a bodge, but today I'd do an in context edit of the full assembly, followed by a transform copy in place, then a section cut with a surface, then squirt this to a new assembly.

    I'd use the new at assy as the transform will kill all the nice instancing the original assembly had.

    For this specific case then perhaps squirt just the sectioned engine block parts back to the original assembly, then show or hide either the full or sectioned parts.

    Assembly configurations would be awesome here.

    Actually I might not use the surface method as that'll leave many split parts.  Might build a solid for the void and then Boolean remove it from just the parts to be sectioned and hidden. That way it will also delete the unwanted parts as well as carry out the section but leave anything not included in the merge scope whole.
