Difficulties Obtaining Path for Lofting

dozerdroid — Sun, 02 May 2021 01:03:03 GMT

I have written a simple program to loft two lines but I cannot correctly obtain the path for lofting, any assistance most welcome. Creating the planes, sketches and lines work fine however the lines below don't work so I assume I am missing something basic ? Thanks.

path1 = rootComp.features.createPath(line1)

path2 = rootComp.features.createPath(line2)

def createNewComponent(rootComp😞

allOccs = rootComp.occurrences

newOcc = allOccs.addNewComponent(adsk.core.Matrix3D.create())

return newOcc.component

def run(context😞

ui = None

try:

app = adsk.core.Application.get()

ui = app.userInterface

design = app.activeProduct # active design

rootComp = design.rootComponent # root component of active design, top level in browser

hullComponent = createNewComponent(rootComp) # create a new hull component

hullComponent.name = "hull"

planesObj = hullComponent.constructionPlanes # returns planes object

xyPlane = hullComponent.xYConstructionPlane # variable representing the xy plane

# add construction plane 1, add sketch and line

planeInput1 = planesObj.createInput() # create construction planes

offsetValue1 = adsk.core.ValueInput.createByReal(1.0)

planeInput1.setByOffset(xyPlane, offsetValue1)

plane1 = planesObj.add(planeInput1)

plane1.name = "bulkhead 1"

sketchesObj = hullComponent.sketches # returns sketches object

sketch1 = sketchesObj.add(plane1)

sketch1.name = "bulkhead 1 sketch 1" # create sketch on construction plane

lines1 = sketch1.sketchCurves.sketchLines

line1 = lines1.addByTwoPoints(adsk.core.Point3D.create(2.0, 3.0, 0.0),adsk.core.Point3D.create(4.0, 5.0, 0.0))

# add construction plane 2, add sketch and line

planeInput2 = planesObj.createInput()

offsetValue2 = adsk.core.ValueInput.createByReal(3.0)

planeInput2.setByOffset(xyPlane, offsetValue2)

plane2 = planesObj.add(planeInput2)

plane2.name = "bulkhead 2"

sketch2 = sketchesObj.add(plane2)

sketch2.name = "bulkhead 2 sketch 1" # create sketch on construction plane

lines2 = sketch2.sketchCurves.sketchLines

line2 = lines2.addByTwoPoints(adsk.core.Point3D.create(3.0, 4.0, 0.0),adsk.core.Point3D.create(5.0, 6.0, 0.0))

# everything above works fine, so lets try a loft between these two lines

path1 = rootComp.features.createPath(line1)

path2 = rootComp.features.createPath(line2)

#I also tried as below ?

#path1 = adsk.fusion.Path.create(line1, adsk.fusion.ChainedCurveOptions.noChainedCurves)

#path2 = adsk.fusion.Path.create(line2, adsk.fusion.ChainedCurveOptions.noChainedCurves)

# create a surface loft feature between the two lines

new_feature = adsk.fusion.FeatureOperations.NewBodyFeatureOperation

loft_features = rootComp.features.loftFeatures

loft_input = loft_features.createInput(new_feature)

loft_sections = loft_input.loftSections

loft_sections.add(path1)

loft_sections.add(path2)

loft_features.add(loft_input)

Hi @dozerdroid .

Since we are creating a sketch with a new occurrence, we will need to get the createPath from the same features as the sketch.

・・・ # everything above works fine, so lets try a loft between these two lines # path1 = rootComp.features.createPath(line1) # path2 = rootComp.features.createPath(line2) path1 = hullComponent.features.createPath(line1) path2 = hullComponent.features.createPath(line2) ・・・

The same will be true for loftFeatures.

# create a surface loft feature between the two lines new_feature = adsk.fusion.FeatureOperations.NewBodyFeatureOperation # loft_features = rootComp.features.loftFeatures loft_features = hullComponent.features.loftFeatures loft_input = loft_features.createInput(new_feature)
