Retrieve extruded sketch from OnShape API by GeoID

elias_berger506

Hello,

Im trying to export all Sketch and Extrude Operations of a CAD Model via API for downstream processing. Ultimately I want to create a datastructure similar to this:



I can retrieve the edges and constraints using the endpoint /partstudios/d/{did}/{wvm}/{wvmid}/e/{eid}/features. No problem here. But for extrude operations I receive 

{

        "type" : 148,

        "typeName" : "BTMParameterQueryList",

        "message" : {

          "queries" : [ {

            "type" : 138,

            "typeName" : "BTMIndividualQuery",

            "message" : {

              "geometryIds" : [ "JGC" ],

              "hasUserCode" : false,

              "nodeId" : "Fw7bheyuFAclyzY"

            }

          } ],

          "parameterId" : "entities",

          "hasUserCode" : false,

          "nodeId" : "YwtNXy9HOwP0MsqL"

}

Now I don't know how I can resolve the geometryId "JGC" into a sketch entity, because I need to know which sketch is extruded. Is there any featurescript function or API call do resolve this?

Any help is greatly appreciated!

Last modifying operator is the closest you'll get from an entity id.

The other option is to go through the feature tree and at each point in the feature tree (ie do an evaluateFeaturescript with rollback index set), get qcreatedby and evaluate it to get everything createdd by each feature and cross reference to the input ids. Bit more brute force, but might be useful for your data model.
