Get Assembly Mass Properties With API

duncan_abbotduncan_abbot Member Posts: 2
Hi, I can measure an assembly's mass properties with the GUI tool in the browser, but I need to be able to get these with the API like I would for a Parts Studio. Is this an available feature and/or is there a workaround? I've also not been able to hit the green checkmark in the mass measure tool popup in my assembly despite giving it the correct inputs with no errors.

    Yes, there is one in PartStudios.  /partstudios/d/:did/[wvm]/:wvm/e/:eid/massproperties

    Or if you meant in Featurescript, you're looking for:

    evApproximateMassProperties (context is Context, arg is map) returns MassProperties

    In the UI, i believe the Green checkmark is disabled.  There is no way to "accept" mass properties measurements.

    @alan_baljeu could you drop a link to where the `massproperties` value is documented in the API? It is being frustratingly hard to find.
