@OPPATTERN: INVALID_INPUT

nir_naron

Trying to duplicate a user-selected line. No idea why these two Featurescripts attached below aren't working.

@NeilCooke HELP!

Also, side questions:

1) What's the best way to have the pattern be perpendicular to the line? Currently they're in the same direction. I was hoping to be able to go <evvLine.direction.normal> though it seems like that's not the way it works.

2) How do I get <selctedLine>'s start-point and end-point? The start-point is <evvLine.origin> but I'm not sure about the end-point.

Thanks!

FeatureScript 2345; import(path : "onshape/std/common.fs", version : "2345.0"); annotation { "Feature Type Name" : "Pattern Line"} export const patternLine = defineFeature(function(context is Context, id is Id, definition is map) precondition { annotation { "Name" : "Select Line:", "Filter" : EntityType.EDGE, "MaxNumberOfPicks" : 1 } definition.selectedLine is Query; } { const selectedLine = definition.selectedLine; debug(context, selectedLine); const evvLine = evEdgeTangentLine(context, { "edge" : selectedLine, "parameter" : 0 }); debug(context, evvLine); opPattern(context, id + "pattern1", { "entities" : selectedLine, "transforms" : [transform(evvLine.direction*inch)], "instanceNames" : ["Copy1"] }); }); // annotation { "Feature Type Name" : "Pattern Line Wierdly" } // export const patternLineWierdly = defineFeature(function(context is Context, id is Id, definition is map) // precondition // { // annotation { "Name" : "Select Line:", "Filter" : EntityType.EDGE, "MaxNumberOfPicks" : 1 } // definition.selectedLine is Query; // } // { // const selectedLine = definition.selectedLine; // debug(context, selectedLine); // const evvLine = evEdgeTangentLine(context, { // "edge" : selectedLine, // "parameter" : 0 // }); // opExtractWires(context, id + "opExtractWires1", { // "edges" : selectedLine // }); // debug(context, qCreatedBy(id + "opExtractWires1", EntityType.EDGE)); // opPattern(context, id + "pattern1", { // "entities" : qCreatedBy(id + "opExtractWires1", EntityType.EDGE), // "transforms" : [transform(evvLine.direction*inch)], // "instanceNames" : ["Copy1"] // }); // });

It's what it says - the input to the feature is a query for an edge, whereas opPattern takes bodies and faces (see https://cad.onshape.com/FsDoc/library.html#opPattern-Context-Id-map ).

So either you need to have the feature take a wire body, or put the edge query through qOwnerBody before passing it to opPattern. Here, I'm doing the former: https://cad.onshape.com/documents/94ddc4d34e104cb58a6e2814/w/6095cff03382e4a3f5843d49/e/f0ceb4faf6d6ba5f60d27fb4

Oh, and for your side questions:

1. There's an infinite number of vectors perpendicular to a line. Is the input necessarily a sketch entity? Then you can get its sketch normal with evOwnerSketchPlane and do a cross product to get a perpendicular direction.
2. Probably the easiest way is evvLine.origin + evvLine.direction * evLength(context, { "entities": selectedLine }); (untested, so YMMV).

Awsome! Whats does including <EntityType.BODY> in the annotation Filter acctualy mean? Why can't it filter just based on <BodyType.WIRE>?
