Is the MateConnector.fs code the only way to do in-context inference in a script?

joshtargo

The only way I've ever been able to use inferred MC's as inputs while modeling in-context is with this exact code, even the requirement of naming the function "mateConnector".

Do I need to use this exact code as the basis for these types of scripts, or is there a more universal/normal way to do it?

FeatureScript 2960;
import(path : "onshape/std/common.fs", version : "2960.0");
export import(path : "onshape/std/origincreationtype.gen.fs", version : "2960.0");
export import(path : "onshape/std/entityinferencetype.gen.fs", version : "2960.0");

annotation {
    "Feature Type Name" : "Context MC Test",
    "Feature Type Description" : "Minimal in-context mate connector from a single entity pick."
}
export const mateConnector = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Origin type", "UIHint" : UIHint.ALWAYS_HIDDEN }
        definition.originType is OriginCreationType;

        annotation { "UIHint" : UIHint.ALWAYS_HIDDEN }
        definition.entityInferenceType is EntityInferenceType;

        annotation { "UIHint" : UIHint.ALWAYS_HIDDEN }
        definition.secondaryOriginQuery is Query;

        annotation { "UIHint" : UIHint.ALWAYS_HIDDEN }
        definition.originAdditionalQuery is Query;

        annotation { "Name" : "Specify normal", "UIHint" : UIHint.ALWAYS_HIDDEN }
        definition.specifyNormal is boolean;

        annotation { "Name" : "Normal x", "UIHint" : UIHint.ALWAYS_HIDDEN }
        isReal(definition.nx, { (unitless) : [ -1, 1, 1 ] } as RealBoundSpec);

        annotation { "Name" : "Normal y", "UIHint" : UIHint.ALWAYS_HIDDEN }
        isReal(definition.ny, { (unitless) : [ -1, 1, 1 ] } as RealBoundSpec);

        annotation { "Name" : "Normal z", "UIHint" : UIHint.ALWAYS_HIDDEN }
        isReal(definition.nz, { (unitless) : [ -1, 1, 1 ] } as RealBoundSpec);

        annotation { "Name" : "Location",
             "Filter" : (EntityType.EDGE || EntityType.VERTEX || EntityType.FACE) && AllowMeshGeometry.YES,
             "MaxNumberOfPicks" : 1 }
        definition.originQuery is Query;
    }
    {
        const csys = evMateConnectorCoordSystem(context, definition);

        opMateConnector(context, id + "mc1", {
            "owner" : qNothing(),
            "coordSystem" : csys
        });
    },
    {
        "originType" : OriginCreationType.ON_ENTITY,
        "entityInferenceType" : EntityInferenceType.POINT,
        "secondaryOriginQuery" : qNothing(),
        "originAdditionalQuery" : qNothing(),
        "specifyNormal" : false,
        "nx" : 0.0,
        "ny" : 0.0,
        "nz" : 0.0
    });
