Featurescript - in a sketch how to determine if point is on a face

ian_mctavish

I'm trying to create a featurescript that creates a 1" grid of points on a face. If the selected face is parallel to the top plane I can easily find the minimum and maximum x and y values. What I am struggling with is if the face is in a different orientation - how do I determine the minimum/maximum values of x and y in relation to the sketch?

If you are trying to find if a point is on a face, you have two options:
qContainsPoint(face,point), and then check if the query is empty with isQueryEmpty()
or
evDistance() and check if the face/point distance is zero

If you want to find the bounds of the face, you can use evBox3d(), and specify the coordinate system of the sketch.

Without knowing the specifics of what you are trying to accomplish, hard to know which to recommend, but that should help at least a little bit.

Caden,

Thanks, I am trying qContainsPoint. Here is the code I am using:

//facePlane is Plane tangent to the selected face: definition.targetFace
//definition.targetFace is a query from a face that the user selects
var vectorToCheck is Vector = planeToWorld(facePlane, vector(0,0)*inch);
var pointToCheck = toWorld(planeToCSys(facePlane), vectorToCheck);
println(qContainsPoint(definition.targetFace, pointToCheck));
println("");
println(isQueryEmpty(context, qContainsPoint(definition.targetFace, pointToCheck)));

Now vectorToCheck should be on the face, however I am getting true for the isQueryEmpty (full output below). Thanks for any insights you can provide.

{ point : [ 1.1102230246251565e-16 , 0 , 0.006350000000000001 ] , queryType : CONTAINS_POINT , subquery : { queryType : UNION , subqueries : [ { disambiguationData : [ { disambiguationType : ORIGINAL_DEPENDENCY , originals : [ { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : g1bWyhonVgaM.bottom } , { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : g1bWyhonVgaM.top } , { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : g1bWyhonVgaM.left } , { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : L8eKFDnIzZjc0.MirrorCS } , { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : 7Wii66VG1rhd0.MirrorCS } , { entityType : EDGE , historyType : CREATION , operationId : [ Fo1W4E0qGbUNqs8_0.wireOp ] , queryType : SKETCH_ENTITY , sketchEntityId : Je0q0qDnAOdG0.MirrorCS } ] } ] , entityType : FACE , historyType : CREATION , isStart : false , operationId : [ Fu4c1LKMRjZ3SBK_0.opExtrude ] , queryType : CAP_FACE } ] } }

true

Have you done addDebugPoint and addDebugEntity to see if the point you are checking really is on the target face?

You can also sanity check with evDistance and see if the distance is zero.

I got it working - I should have used vectorToCheck instead of pointToCheck. Thanks so much!
