Hello,
I'm trying to create a script to allow me to sweep a largish number of curves with the same profile (that tapers along the length of the curve, but only in one dimension), but would like to be able to adjust the dimensions of that profile after the fact using parameters. I currently have it in a state where it will create the required profiles at each end of the curve based off of my User Parameters but I understand from this post that in order to have it directly reference the parameter (and thus be adjustable) I need to add dimensions to the sketch and link them to the parameters.
My defined user parameters for reference:
BSOx and BSOy are the size of the profile with all the others based off of them in order to draw a 3 point rectangle (not good with Python, only started using it this afternoon and was trying to keep things as simple as possible for myself, I'm sure it would be better to do it with math within the script).
Here is the entire script:
import adsk.core, adsk.fusion, traceback
def run(context):
ui = None
try:
app = adsk.core.Application.get()
ui = app.userInterface
product = app.activeProduct
design = adsk.fusion.Design.cast(product)
if not design:
ui.messageBox('It is not supported in current workspace, please change to MODEL workspace and try again.')
return
sel = ui.selectEntity('Select a path to create loft', 'Edges,SketchCurves')
selObj = sel.entity
comp = design.rootComponent
userParams = design.userParameters
# create path
feats = comp.features
chainedOption = adsk.fusion.ChainedCurveOptions.connectedChainedCurves
if adsk.fusion.BRepEdge.cast(selObj):
chainedOption = adsk.fusion.ChainedCurveOptions.tangentChainedCurves
path = adsk.fusion.Path.create(selObj, chainedOption)
path = feats.createPath(selObj)
# create planes at each end
planes = comp.constructionPlanes
planeInput = planes.createInput()
planeInput.setByDistanceOnPath(selObj, adsk.core.ValueInput.createByReal(0))
plane1 = planes.add(planeInput)
planeInput.setByDistanceOnPath(selObj, adsk.core.ValueInput.createByReal(1))
plane2 = planes.add(planeInput)
#create sketch for origin
sketches = comp.sketches
sketch = sketches.add(plane1)
#create rectangle
oCentre = plane1.geometry.origin
oCentre = sketch.modelToSketchSpace(oCentre)
oCorner1 = adsk.core.Point3D.create(userParams.itemByName('nBSOox').value,userParams.itemByName('nBSOoy').value)
oCorner2 = adsk.core.Point3D.create(userParams.itemByName('BSOox').value,userParams.itemByName('nBSOoy').value)
oCorner3 = adsk.core.Point3D.create(userParams.itemByName('BSOox').value,userParams.itemByName('BSOoy').value)
oRect1 = sketch.sketchCurves.sketchLines.addThreePointRectangle(oCorner1,oCorner2,oCorner3)
# Add a dimension constraint and edit it's parameter to be dependent on 'BSOx'.
dims = sketch.sketchDimensions
oRectDim = dims.addDistanceDimension(oCorner1, oCorner2, adsk.fusion.DimensionOrientations.AlignedDimensionOrientation, adsk.core.Point3D.create(0,-3,0))
oRectDim.parameter.expression = 'BSOx'
profile1 = sketch.profiles[0]
#create sketch for termination end
sketches = comp.sketches
sketch = sketches.add(plane2)
#create rectangle from centre and corner
tCentre = plane2.geometry.origin
tCentre = sketch.modelToSketchSpace(tCentre)
tCorner1 = adsk.core.Point3D.create(userParams.itemByName('BSTx').value,userParams.itemByName('BSTy').value)
sketch.sketchCurves.sketchLines.addCenterPointRectangle(tCentre, tCorner1)
profile2 = sketch.profiles[0]
#Create Loft
loft1 = comp.features.loftFeatures
loftInput = loft1.createInput(adsk.fusion.FeatureOperations.NewBodyFeatureOperation)
loftSectionsObj = loftInput.loftSections
loftSectionsObj.add(profile1)
loftSectionsObj.add(profile2)
loftPath = loftInput.centerLineOrRails
loftPath.addCenterLine(path)
loftInput.isSolid = True
# Create loft feature
loft1.add(loftInput)
app.activeViewport.refresh()
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
My issue is with the lines
# Add a dimension constraint and edit it's parameter to be dependent on 'radius'.
dims = sketch.sketchDimensions
oRectDim = dims.addDistanceDimension(oCorner1, oCorner2, adsk.fusion.DimensionOrientations.AlignedDimensionOrientation, adsk.core.Point3D.create(0,-3,0))
oRectDim.parameter.expression = 'BSOx'
No matter what I seem to try, I get TypeError: Wrong number or type of arguments for overloaded function 'SketchDimensions_addDistanceDimension' when running the script. The effect was the same whether I used a centrepoint rectangle and tried to measure from the centre to the corner, or as it is now with an unnecessary number of different parameters in order to draw a 3 point rectangle (I thought it was maybe due to the points not being on the same horizontal line).
I believe, probably incorrectly, that my issue is with the orientation argument as I cannot fathom what could be wrong with the others as they are all defined points.
I've cobbled this together from various other scripts I've found so if there is a much easier way to achieve my desired outcome please let me know.
Thanks in advance
Pete
Edit: Sorry, to clarify I have tried various different things for each of the arguments of addDistanceDimension; for orientation specifically I have tried (having seen them used elsewhere): 0, adsk.fusion.DimensionOrientations.HorizontalDimensionOrientation, I think one other attempt but I can't find it now
