Add Rectangular Pattern Feature to Component

ebunn3 — Fri, 12 Aug 2022 13:33:57 GMT

Hi,

I've pasted a code example below that creates a Rectangular Pattern Feature and adds it to a new document. I want to re-configure this so it adds the pattern feature to a new component within an active file instead of creating a new file and adding it to that one. Can someone help me re-configure this example to do this?

I've tried to change by passing in a new component and using it as my root component and get the following error:

Traceback (most recent call last): File "C:/Users/ebunn/AppData/Roaming/Autodesk/Autodesk Fusion 360/API/Scripts/Nesting_True_Type_By_Points_Comp/Nesting_True_Type_By_Points_Comp.py", line 736, in <module> PatternBodies(preN[1],newComp,numX,moveX,numY,moveY) File "C:/Users/ebunn/AppData/Roaming/Autodesk/Autodesk Fusion 360/API/Scripts/Nesting_True_Type_By_Points_Comp/Nesting_True_Type_By_Points_Comp.py", line 683, in PatternBodies rectangularFeature = rectangularPatterns.add(rectangularPatternInput) File "C:\Users/ebunn/AppData/Local/Autodesk/webdeploy/production/8814bf1cdd9624465cbdf7f023becc629a5ffbe5/Api/Python/packages\adsk\fusion.py", line 28366, in add return _fusion.RectangularPatternFeatures_add(self, input) RuntimeError: 2 : InternalValidationError : Utils::getObjectPath(obj.get(),objPath, nullptr,path)

Here is an example of the attempted change. The new component I am trying to add it to is called newComp. I am pulling the bodies from another component passed in as comp:

def PatternBodies(comp,newComp,quantityOne,distanceOne,quantityTwo,distanceTwo😞

app = adsk.core.Application.get()

ui = app.userInterface

# Create a document.

# doc = app.documents.add(adsk.core.DocumentTypes.FusionDesignDocumentType)

product = app.activeProduct

design = adsk.fusion.Design.cast(product)

# # Get the root component of the active design.

rootComp = newComp#design.rootComponent

#Get the document units (bookmark:units)

units = design.unitsManager.defaultLengthUnits

# Create input entities for rectangular pattern

inputEntites = adsk.core.ObjectCollection.create()

for i in comp.bRepBodies:

inputEntites.add(i)

import adsk.core, adsk.fusion, traceback def run(context): ui = None try: app = adsk.core.Application.get() ui = app.userInterface # Create a document. doc = app.documents.add(adsk.core.DocumentTypes.FusionDesignDocumentType) product = app.activeProduct design = adsk.fusion.Design.cast(product) # Get the root component of the active design. rootComp = design.rootComponent # Create sketch sketches = rootComp.sketches sketch = sketches.add(rootComp.xZConstructionPlane) sketchCircles = sketch.sketchCurves.sketchCircles centerPoint = adsk.core.Point3D.create(0, 0, 0) sketchCircles.addByCenterRadius(centerPoint, 3.0) # Get the profile defined by the circle. prof = sketch.profiles.item(0) # Create an extrusion input extrudes = rootComp.features.extrudeFeatures extInput = extrudes.createInput(prof, adsk.fusion.FeatureOperations.NewBodyFeatureOperation) # Define that the extent is a distance extent of 5 cm. distance = adsk.core.ValueInput.createByReal(5) extInput.setDistanceExtent(False, distance) # Create the extrusion. ext = extrudes.add(extInput) # Get the body created by extrusion body = ext.bodies.item(0) # Create input entities for rectangular pattern inputEntites = adsk.core.ObjectCollection.create() inputEntites.add(body) # Get x and y axes for rectangular pattern xAxis = rootComp.xConstructionAxis yAxis = rootComp.yConstructionAxis # Quantity and distance quantityOne = adsk.core.ValueInput.createByString('3') distanceOne = adsk.core.ValueInput.createByString('8 cm') quantityTwo = adsk.core.ValueInput.createByString('3') distanceTwo = adsk.core.ValueInput.createByString('8 cm') # Create the input for rectangular pattern rectangularPatterns = rootComp.features.rectangularPatternFeatures rectangularPatternInput = rectangularPatterns.createInput(inputEntites, xAxis, quantityOne, distanceOne, adsk.fusion.PatternDistanceType.SpacingPatternDistanceType) # Set the data for second direction rectangularPatternInput.setDirectionTwo(yAxis, quantityTwo, distanceTwo) # Create the rectangular pattern rectangularFeature = rectangularPatterns.add(rectangularPatternInput) except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Appreciate the help.

Hi @ebunn3 ,

Please find attached a script for it.

Just to clarify: the bodies created in the rectangular pattern are kept in the source component, so at the end of the function it moves them to the new created component.

def PatternBodies( srcComp: adsk.fusion.Component, destOccu: adsk.fusion.Occurrence, quantityOne: adsk.core.ValueInput, distanceOne: adsk.core.ValueInput, quantityTwo: adsk.core.ValueInput, distanceTwo: adsk.core.ValueInput): try: # Create input entities for rectangular pattern inputEntites = adsk.core.ObjectCollection.create() for i in srcComp.bRepBodies: inputEntites.add(i) # Get x and y axes for rectangular pattern xAxis = srcComp.xConstructionAxis yAxis = srcComp.yConstructionAxis # Create the input for rectangular pattern rectangularPatterns = srcComp.features.rectangularPatternFeatures rectangularPatternInput = rectangularPatterns.createInput(inputEntites, xAxis, quantityOne, distanceOne, adsk.fusion.PatternDistanceType.SpacingPatternDistanceType) # Set the data for second direction rectangularPatternInput.setDirectionTwo(yAxis, quantityTwo, distanceTwo) # Create the rectangular pattern rectangularFeature = rectangularPatterns.add(rectangularPatternInput) # move the bodies to the destComp, since the new bodies are created in the same component they belongs bodyArray = [body for body in rectangularFeature.bodies] # I had to create this body array, because iterating over rectangularFeature.bodies gives an error on item #8. for body in bodyArray: body.moveToComponent(destOccu) except: app.log(f'Error in PatternBodies: {traceback.format_exc()}') def rectangularPattern(): try: #source component to take bodies from rootComp = adsk.fusion.Design.cast(app.activeProduct).rootComponent srcComp = rootComp #create the new component matrix = adsk.core.Matrix3D.create() destOccu = rootComp.occurrences.addNewComponent(matrix) destComp = destOccu.component destComp.name = 'newComponent' # create ValueInput's for each dimension quantityOne = adsk.core.ValueInput.createByString('3') distanceOne = adsk.core.ValueInput.createByString('8 cm') quantityTwo = adsk.core.ValueInput.createByString('3') distanceTwo = adsk.core.ValueInput.createByString('8 cm') PatternBodies(srcComp, destOccu, quantityOne, distanceOne, quantityTwo, distanceTwo) except: app.log(f'Error in rectangularPattern: {traceback.format_exc()}')

Hope this help to solve your problem.

Regards,

Jorge

Walter,

See screenshot below. I want to use the bodies in Component 1:1 and create a new component that will contain the rectangular pattern.

Thanks for all of the help.

Give a try at this script which worked for me.

If you have two bodies on source component, you will get 18 (= 2 x 3 x 3) in the new component.

def PatternBodies( srcComp: adsk.fusion.Component, destOccu: adsk.fusion.Occurrence, quantityOne: adsk.core.ValueInput, distanceOne: adsk.core.ValueInput, quantityTwo: adsk.core.ValueInput, distanceTwo: adsk.core.ValueInput): try: # Create input entities for rectangular pattern inputEntites = adsk.core.ObjectCollection.create() for i in srcComp.bRepBodies: # copy bodies to dest component cpb = destOccu.component.features.copyPasteBodies.add(i) inputEntites.add(cpb.bodies[0]) # Get x and y axes for rectangular pattern xAxis = destOccu.component.xConstructionAxis yAxis = destOccu.component.yConstructionAxis # Create the input for rectangular pattern rectangularPatterns = destOccu.component.features.rectangularPatternFeatures rectangularPatternInput = rectangularPatterns.createInput(inputEntites, xAxis, quantityOne, distanceOne, adsk.fusion.PatternDistanceType.SpacingPatternDistanceType) # Set the data for second direction rectangularPatternInput.setDirectionTwo(yAxis, quantityTwo, distanceTwo) # Create the rectangular pattern rectangularFeature = rectangularPatterns.add(rectangularPatternInput) except: app.log(f'Error in PatternBodies: {traceback.format_exc()}') def rectangularPattern(): try: #source component to take bodies from rootComp = adsk.fusion.Design.cast(app.activeProduct).rootComponent srcComp = rootComp.occurrences.item(0).component # <---- bodies from first component under root component; change according to your design #create the new component matrix = adsk.core.Matrix3D.create() destOccu = rootComp.occurrences.addNewComponent(matrix) destComp = destOccu.component destComp.name = 'newComponent' # create ValueInput's for each dimension quantityOne = adsk.core.ValueInput.createByString('3') distanceOne = adsk.core.ValueInput.createByString('8 cm') quantityTwo = adsk.core.ValueInput.createByString('3') distanceTwo = adsk.core.ValueInput.createByString('8 cm') PatternBodies(srcComp, destOccu, quantityOne, distanceOne, quantityTwo, distanceTwo) except: app.log(f'Error in rectangularPattern: {traceback.format_exc()}')

The change I made is to copy source bodies to new component before making the rect pattern, instead of moving the result bodies at the end.

Jorge

I've made a few changes to the script allowing a component selection first. Just wanted to post the final script for anyone else's benefit. Thanks again to @Jorge_Jaramillo for the great solution.
