Hi,
I am having some difficulty to understand why the fillet behavior works differently when using Python script versus using the UI. I have a script that generates a lot of splines (SketchFittedSpline) and lines (SketchLine). Eventually the lines intersect the splines and should be rounded at the at the intersection using the fillet operator.
I dont not face any issues when using the fillet operator between lines and arcs but splines are more difficult to use. To illustrate the problem, I extracted a spline from my model and attached a sample code.
"""This file acts as the main module for this script."""
import traceback
import adsk.core
import adsk.fusion
# import adsk.cam
from adsk.core import DocumentTypes, ObjectCollection, Point3D
from adsk.fusion import Design
# Initialize the global variables for the Application and UserInterface objects.
app = adsk.core.Application.get()
ui = app.userInterface
def run(_context: str):
"""This function is called by Fusion when the script is run."""
newDocumentName = "Test"
newDocument = app.documents.add(DocumentTypes.FusionDesignDocumentType)
newDocument.name = newDocumentName
design = Design.cast(app.activeProduct)
rootComp = design.rootComponent
sketches = rootComp.sketches
if not newDocument.activate():
ui.messageBox("Newly created document could not be activated!")
return
sketch = sketches.add(rootComp.xYConstructionPlane)
sketch.name = "Test"
fitPoints: ObjectCollection = ObjectCollection.create()
startFitPoint = Point3D.create(0.18336113476039656, 3.522766673615777, 0)
midFitPoint = Point3D.create(0.21718981258706083, 3.7627597813225755, 0)
endFitPoint = Point3D.create(0.16831464666888074, 4.051349328459134, 0)
fitPoints.add(startFitPoint)
fitPoints.add(midFitPoint)
fitPoints.add(endFitPoint)
fittedSpline = sketch.sketchCurves.sketchFittedSplines.add(fitPoints)
startPoint = Point3D.create(-1.0, 3.18)
endPoint = Point3D.create(0.45, 3.6)
line = sketch.sketchCurves.sketchLines.addByTwoPoints(startPoint, endPoint)
sketch.sketchCurves.sketchArcs.addFillet(line, startPoint, fittedSpline, endFitPoint, 0.4)
try:
# Your code goes here.
ui.messageBox(f'"{app.activeDocument.name}" is the active Document.')
except: # pylint:disable=bare-except
# Write the error message to the TEXT COMMANDS window.
app.log(f"Failed:\n{traceback.format_exc()}")
When adding the fillet via UI, this works out of the box:
I am probably missing something when using Python. Any ideas? Are there any other best practices to consider when using the fillet operator with Splines?
