Error with Rectangular Pattern on Inserted Component

[Hyger]

I was about to ask for help with my code, because i kept getting this error message

and i could remove it by editing the feature (rectangular pattern) and then immediately clicking ok

 

But then it occurred to me that maybe it's the same problem as in my previous post ->

https://forums.autodesk.com/t5/fusion-api-and-scripts/rigid-joint-between-an-external-inserted-compo...

that there is a problem with inserted components, so insted of making the pattern from the inserted component, i used (the "hack"/solution Jorge_Jaramillo suggested as a solution in my previous post) the parent component that i created for the inserted component and that fixed the error

Here is the 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 line
lines = sketch.sketchCurves.sketchLines
line = lines.addByTwoPoints(adsk.core.Point3D.create(0, 0, 0), adsk.core.Point3D.create(0, 200, 0))

#Add a sketch point a distance from each end
points = sketch.sketchPoints
sketchPoint = points.add(adsk.core.Point3D.create(0, 10, 0))

#Find components
exampleComponent = app.data.activeHub.dataProjects.item(0).rootFolder.dataFolders.itemByName("Autodesk Example").dataFiles.item(0)

#Insert Components (Using forum hack https://forums.autodesk.com/t5/fusion-api-and-scripts/rigid-joint-between-an-external-inserted-component-and-a-sketch/td-p/12941821)
instantiate = root.occurrences
forumHack = instantiate.addNewComponent(adsk.core.Matrix3D.create())
instantiateComponent = forumHack.component.occurrences.addByInsert(exampleComponent, adsk.core.Matrix3D.create(), True)
instantiateComponent.isGroundToParent = True

#Get origin points
originComponent = forumHack.component.originConstructionPoint

#Create joint geometry
joints = root.joints

jointPointComponent = adsk.fusion.JointGeometry.createByPoint(originComponent)
jointPointSketch = adsk.fusion.JointGeometry.createByPoint(sketchPoint)
joint = joints.createInput(jointPointComponent, jointPointSketch)

#Joint settings
joint.isFlipped = False
joint.setAsRigidJointMotion()

#Create joints
joints.add(joint)

#Rectrangular pattern inputs
rectangularPatternComponents = adsk.core.ObjectCollection.create()

##### ---->>  This will create the error  <<----- #####
#rectangularPatternComponents.add(forumHack) # This works
rectangularPatternComponents.add(instantiateComponent) # This doesn't

componentAmount = adsk.core.ValueInput.createByString('3')
patternDistance = adsk.core.ValueInput.createByString("500")
patternDistType = adsk.fusion.PatternDistanceType.ExtentPatternDistanceType

#Create rectangular pattern
rectangularPattern = root.features.rectangularPatternFeatures

rectangularPatternInput = rectangularPattern.createInput(rectangularPatternComponents, line, componentAmount, patternDistance, patternDistType)
rectangularPatternInput.setDirectionTwo(line, adsk.core.ValueInput.createByString('1'), adsk.core.ValueInput.createByString('0 mm'))

rectangularPattern.add(rectangularPatternInput)

maybe i'm doing something wrong?

if not how do i report this bug?

thanks in advance

Hi
Did you find a solution? I just ran into the same problem and I'm running out of ideas. I also noticed that when the loaded component is in the rootComponent the program works fine, but if I move the loaded component to another component and try to make a rectanglePattern I get exactly the same result as you.

Here's a modified version of the original program. The change that matters is that I'm calling createForAssemblyContext to get the origin point in the context of the root component. This is often called a "proxy" of the real point. The user manual discusses this.

def run(context):
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface
        des = adsk.fusion.Design.cast(app.activeProduct)
        root = adsk.fusion.Component.cast(des.rootComponent)

        #Make sketch on selected face
        sketch = root.sketches.add(root.xYConstructionPlane)

        #Add line
        lines = sketch.sketchCurves.sketchLines
        line = lines.addByTwoPoints(adsk.core.Point3D.create(0, 0, 0), adsk.core.Point3D.create(0, 200, 0))

        #Add a sketch point a distance from each end
        points = sketch.sketchPoints
        sketchPoint = points.add(adsk.core.Point3D.create(0, 10, 0))

        #Find components
        project = app.data.activeHub.dataProjects.item(0)
        exampleComponent = project.rootFolder.dataFolders.itemByName("Autodesk Example").dataFiles.item(0)
        occ = root.occurrences.addByInsert(exampleComponent, adsk.core.Matrix3D.create(), True)

        #Get origin points
        originPoint = occ.component.originConstructionPoint

        #*** This is the main thing that was missing ***
        originPoint = originPoint.createForAssemblyContext(occ)

        #Create joint geometry
        joints = root.joints

        jointPointComponent = adsk.fusion.JointGeometry.createByPoint(originPoint)
        jointPointSketch = adsk.fusion.JointGeometry.createByPoint(sketchPoint)
        joint = joints.createInput(jointPointComponent, jointPointSketch)

        #Joint settings
        joint.isFlipped = False
        joint.setAsRigidJointMotion()

        #Create joints
        joints.add(joint)

        #Rectrangular pattern inputs
        rectangularPatternComponents = adsk.core.ObjectCollection.create()

        rectangularPatternComponents.add(occ)

        componentAmount = adsk.core.ValueInput.createByString('3')
        patternDistance = adsk.core.ValueInput.createByString("15")
        patternDistType = adsk.fusion.PatternDistanceType.ExtentPatternDistanceType

        #Create rectangular pattern
        rectangularPattern = root.features.rectangularPatternFeatures

        rectangularPatternInput = rectangularPattern.createInput(rectangularPatternComponents, line, componentAmount, patternDistance, patternDistType)
        rectangularPatternInput.setDirectionTwo(line, adsk.core.ValueInput.createByString('1'), adsk.core.ValueInput.createByString('0 mm'))

        rectangularPattern.add(rectangularPatternInput)
    except:
        app.log('Failed:\n{}'.format(traceback.format_exc()))

What I mean is that when I use the addByInsert method for the root, the rectangularPattern works fine. However, if I create a component and want to use the addByInsert method for it, the rectangularPattern no longer works fine. The effect is the same as in Hyger. I am attaching a program in which this effect occurs.

Here's a new version of your program where I added one line that creates a proxy of the occurrence. This fixes the issue you're having. It's line 48.

Ha! It works. Although I still don't understand the mechanism of how this proxy works. But it works exactly as I want. Thank you
