Parallel lines

Is it possible to tell if two lines in two different sketches on two different planes are parallel?

Yes, Mr. Brad.Bylls,

... cross product of two parallel vectors equals 0

If there is a tolerance involved consider finding an angle between vectors.

@brad.bylls -San.

There are several ways to get Vector3D from SketchLine, and this is one example.

# Fusion360API Python script import traceback import adsk.core as core import adsk.fusion as fusion def run(context): ui: core.UserInterface = None try: app: core.Application = core.Application.get() ui = app.userInterface des: fusion.Design = app.activeProduct root: fusion.Component = des.rootComponent line1: fusion.SketchLine = root.sketches[0].sketchCurves.sketchLines[0] line2: fusion.SketchLine = root.sketches[1].sketchCurves.sketchLines[0] vector1: core.Vector3D = line1.geometry.asInfiniteLine().direction vector2: core.Vector3D = line2.geometry.asInfiniteLine().direction print(f"is Paralle : {vector1.isParallelTo(vector2)}") except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

The Vector3D object has a method to determine parallelism.
