Rigid joint between an external inserted component and a sketch point fails

Hyger — Tue, 06 Aug 2024 11:19:07 GMT

I'm trying to insert an external component and rigid join it to sketch point, but i'm getting this error

return _fusion.Joints_add(self, input) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ RuntimeError: 3 : Provided input paths for joint are not valid.

this is my code.

app = adsk.core.Application.get() ui = app.userInterface des = adsk.fusion.Design.cast(app.activeProduct) root = adsk.fusion.Component.cast(des.rootComponent) #Select a face to make sketch on face = ui.selectEntity("Select a Planar Face", "PlanarFaces").entity #Make sketch on selected face sketch = root.sketches.add(face) #Add a sketch point points = sketch.sketchPoints sketchPoint = points.add(adsk.core.Point3D.create(0, 10, 0)) #Find component exampleComponent = app.data.activeHub.dataProjects.item(0).rootFolder.dataFolders.itemByName("Autodesk Example").dataFiles.item(0) #Insert Component instantiate = root.occurrences instantiateComponent = instantiate.addByInsert(exampleComponent, adsk.core.Matrix3D.create(), True) #Get origin point originComponent = instantiateComponent.component.originConstructionPoint #Create joint geometry jointPointComponent = adsk.fusion.JointGeometry.createByPoint(originComponent) jointPointSketch = adsk.fusion.JointGeometry.createByPoint(sketchPoint) #Joint settings joints = root.joints joint = joints.createInput(jointPointComponent, jointPointSketch) #joint.angle = adsk.core.ValueInput.createByString('0 deg') #joint.offset = adsk.core.ValueInput.createByString('0 mm') joint.isFlipped = False joint.setAsRigidJointMotion() #Create joint joints.add(joint)

when i do the same manually it's no problem.

hope someone can help me

Hi,

I couldn't make it work as you have it, since I got the same error message everytime a point from the imported component is used to make the joint.

A workaround that worked for me was to import the component as a child of another component, which was created locally.

So the hierarchy looks like the following:

root

sketch (with point1)

component1

importedComponent

Make component1 not grounded to parent (to let it move) and make importedComponent grounded to parent (will move with its parent).

Then make the joint between point1 and component1's originConstructionPoint.

I hope this can help as a workaround for you, while Fusion Team could investigate a possible bug whit this method.

Regards,

Jorge Jaramillo

Thank you! that worked

Although it's kind of a hack, but i'm going to use it until it gets fixed

Thank you again!

I don't believe there is a problem with the API here. Here's a slightly modified version of the original program that works. The difference is that I added line 25 so that the point used later is a proxy of the origin point in the other component. This idea of "proxies" is discussed in the user manual.

app = adsk.core.Application.get() ui = app.userInterface des = adsk.fusion.Design.cast(app.activeProduct) root = adsk.fusion.Component.cast(des.rootComponent) #Select a face to make sketch on face = ui.selectEntity("Select a Planar Face", "PlanarFaces").entity #Make sketch on selected face sketch = root.sketches.add(face) #Add a sketch point points = sketch.sketchPoints sketchPoint = points.add(adsk.core.Point3D.create(0, 10, 0)) #Find component exampleComponent = app.data.activeHub.dataProjects.item(0).rootFolder.dataFolders.itemByName("Autodesk Example").dataFiles.item(0) #Insert Component instantiate = root.occurrences instantiateComponent = instantiate.addByInsert(exampleComponent, adsk.core.Matrix3D.create(), True) #Get origin point originPoint = instantiateComponent.component.originConstructionPoint originPoint = originPoint.createForAssemblyContext(instantiateComponent) #Create joint geometry jointPointComponent = adsk.fusion.JointGeometry.createByPoint(originPoint) jointPointSketch = adsk.fusion.JointGeometry.createByPoint(sketchPoint) #Joint settings joints = root.joints joint = joints.createInput(jointPointComponent, jointPointSketch) #joint.angle = adsk.core.ValueInput.createByString('0 deg') #joint.offset = adsk.core.ValueInput.createByString('0 mm') joint.isFlipped = False joint.setAsRigidJointMotion() #Create joint joints.add(joint)
