Error with Rectangular Pattern on Inserted Component

Hyger — Fri, 09 Aug 2024 21:50:36 GMT

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-component-and-a-sketch/td-p/12941821

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.

import traceback import adsk.fusion import adsk.core def run(context): ui = adsk.core.UserInterface.cast(None) try: app: adsk.core.Application = adsk.core.Application.get() ui = app.userInterface des: adsk.fusion.Design = app.activeProduct root: adsk.fusion.Component = des.rootComponent # get active datafile actDataFile: adsk.core.DataFile = app.activeDocument.dataFile if not actDataFile: ui.messageBox("Save the document once.") return # get datafile ID actId = app.activeDocument.dataFile.id # get the unique data file dataFolder: adsk.core.DataFolder = app.activeDocument.dataFile.parentFolder targetDatafile: adsk.core.DataFile = None dataFiles = dataFolder.dataFiles.asArray() for df in dataFiles: if df.id != actId and df.fileExtension == "f3d": targetDatafile = df break if not targetDatafile: ui.messageBox("Could not find the data file to import.") return instantiate = root.occurrences newComponent = instantiate.addNewComponent(adsk.core.Matrix3D.create()) ##### ---->> This will create the error <<----- ##### # targetComponent = root.occurrences # This works targetComponent = newComponent.component.occurrences # This doesn't ##### ---->> This will create the error <<----- ##### instantiateComponent = targetComponent.addByInsert( targetDatafile, adsk.core.Matrix3D.create(), False ) # Rectrangular pattern inputs rectangularPatternComponents = adsk.core.ObjectCollection.create() rectangularPatternComponents.add(instantiateComponent) 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, root.xConstructionAxis, componentAmount, patternDistance, patternDistType, ) rectangularPatternInput.setDirectionTwo( root.yConstructionAxis, adsk.core.ValueInput.createByString("1"), adsk.core.ValueInput.createByString("0 mm"), ) rectangularPattern.add(rectangularPatternInput) except: if ui: ui.messageBox("Failed:\n{}".format(traceback.format_exc()))

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.

import traceback import adsk.fusion import adsk.core def run(context): ui = adsk.core.UserInterface.cast(None) try: app: adsk.core.Application = adsk.core.Application.get() ui = app.userInterface des: adsk.fusion.Design = app.activeProduct root: adsk.fusion.Component = des.rootComponent # get active datafile actDataFile: adsk.core.DataFile = app.activeDocument.dataFile if not actDataFile: ui.messageBox("Save the document once.") return # get datafile ID actId = app.activeDocument.dataFile.id # get the unique data file dataFolder: adsk.core.DataFolder = app.activeDocument.dataFile.parentFolder targetDatafile: adsk.core.DataFile = None dataFiles = dataFolder.dataFiles.asArray() for df in dataFiles: if df.id != actId and df.fileExtension == "f3d": targetDatafile = df break if not targetDatafile: ui.messageBox("Could not find the data file to import.") return instantiate = root.occurrences newComponent = instantiate.addNewComponent(adsk.core.Matrix3D.create()) ##### ---->> This will create the error <<----- ##### # targetComponent = root.occurrences # This works targetComponent = newComponent.component.occurrences # This doesn't ##### ---->> This will create the error <<----- ##### instantiateComponent = targetComponent.addByInsert( targetDatafile, adsk.core.Matrix3D.create(), False ) #### --->> This line fixes it by creating a proxy of the ocurrence. <<---- ##### instantiateComponent = instantiateComponent.createForAssemblyContext(newComponent) # Rectrangular pattern inputs rectangularPatternComponents = adsk.core.ObjectCollection.create() rectangularPatternComponents.add(instantiateComponent) 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, root.xConstructionAxis, componentAmount, patternDistance, patternDistType, ) rectangularPatternInput.setDirectionTwo( root.yConstructionAxis, adsk.core.ValueInput.createByString("1"), adsk.core.ValueInput.createByString("0 mm"), ) rectangularPattern.add(rectangularPatternInput) except: if ui: ui.messageBox("Failed:\n{}".format(traceback.format_exc()))

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
