}

So now I think that I want to call POST /partstudios/d/{did}/{wvm}/{wvmid}/e/{eid}/featurescript

1. Auto-fill again with the same URL and I get this Request URL (after execute):
https://cad.onshape.com/api/v6/partstudios/d/4aa99028e075fd17f8cbb6c7/v/18d72dc7cc5d2583696cf3d5/e/be2e09e6ee4f95072f5d7d0d/featurescript?rollbackBarIndex=-1
What I don't know is how to fill the Request Body before I do the execute. I think I want to do this query from above:
                {
                  "btType": "BTMInferenceQueryWithOccurrence-1083",
                  "secondEntityQuery": "",
                  "inferenceType": "CENTER",
                  "entityQuery": "query=qCompressed(1.0,\"%B5$QueryM6S12$disambiguationDataA1M2S12$disambiguationTypeS13$ORIGINAL_DEPENDENCYS9$originalsA1C0M5Sa$entityTypeBa$EntityTypeS4$EDGESb$historyTypeS8$CREATIONSb$operationIdB2$IdA1S11.6$FEQIdV8BVgVFiil_3wireOpS9$queryTypeSd$SKETCH_ENTITYSe$sketchEntityIdSc.1.8$9e8h2EnpIvK00startCapR4R5R6R7S7$isStartTR8CbA1S11.9$FyHdFPmgvYfhRPU_3opExtrudeRbS8$CAP_EDGE\",id);",
                  "path": [
                    "MOF67g1zjISR3yEzL"
                  ],
                  "nodeId": "Fhs8ObFxXmpmB7R"
                }

However I have not been able to figure out how to format it for the Request Body.

Thanks.

    Instead of requesting `features` you need to request the assembly document `/assembly/d/{did}/{wvm}/{wvmid}/e/{eid}` and the mate origin properties should be in `features` property of the root assembly.

    Thanks. I see it. Before I think I just missed including the includeMateFeatures option.
  • Nicolas_AmatoNicolas_Amato Member Posts: 3 EDU
    @billyzelsnack I have a question for you. How do you export STLs via the API? I requested a part STL in glassworks and it works, however when I try to request the STL through my own application it ends up responding with a 401. I heard that is the only endpoint that uses a redirect and that you need to include your authorization for the redirect, and I'm not sure how to do that.
  • Nicolas_AmatoNicolas_Amato Member Posts: 3 EDU
    Ok I figured it out. All I needed to do was capture and ignore the redirect URL and send a request with authorization and accept headers.
  • billyzelsnackbillyzelsnack Member Posts: 96 PRO
    Awhile back I wrote a simple c++ example that might be useful for other various stl details.
