add constraint to projections with API

[grosfaignan]

hi 

i have the following error when i try to create constraint between sketch projections and sketch line with api :

Failed:
Traceback (most recent call last):
  File "C:/Users/charl/AppData/Roaming/Autodesk/Autodesk Fusion 360/API/Scripts/NewScript1/NewScript1.py", line 79, in run
    coincidentConstraint = constraints.addCoincident(projectionsP3.item(0),lastFret )
  File "C:/Users/charl/AppData/Local/Autodesk/webdeploy/production/4c84784f9b312b4c6ccb78d46529ebb70d7a5a09/Api/Python/packages\adsk\fusion.py", line 20327, in addCoincident
    return _fusion.GeometricConstraints_addCoincident(self, point, entity)
RuntimeError: 2 : InternalValidationError : sketch == msketch

anyone know what does it mean ?

Hi @grosfaignan .

I don't think anyone can answer this question because there is too little information.

If you want to reach the goal, please provide the code and f3d data you tried.

there is the code :

import adsk.core, adsk.fusion, traceback
import math

defaultBoltName = 'FretBoard 1'
defaultHeadDiameter = 7
defaultBodyDiameter = 10.4
defaultHeadHeight = 24.5
defaultBodyLength = 24.5
defaultCutAngle = 30.0 * (math.pi / 180)
defaultChamferDistance = 4
defaultFilletRadius = 22

# global set of event handlers to keep them referenced for the duration of the command
handlers = []
app = adsk.core.Application.get()
if app:
    ui = app.userInterface

newComp = None

def createNewComponent():
    # Get the active design.
    product = app.activeProduct
    design = adsk.fusion.Design.cast(product)
    rootComp = design.rootComponent
    allOccs = rootComp.occurrences
    newOcc = allOccs.addNewComponent(adsk.core.Matrix3D.create())
    return newOcc.component

def run(context):
    try:
        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


        # 1) Create a new sketch.
        global newComp
        newComp = createNewComponent()
        sketches = newComp.sketches
        xyPlane = newComp.xYConstructionPlane
        xzPlane = newComp.xZConstructionPlane
        sketch = sketches.add(xyPlane)
        sketch.name='MainFrame'
        constraints = sketch.geometricConstraints


        p1 = sketch.sketchPoints.add(adsk.core.Point3D.create(-50, 50, 0))
        p2 = sketch.sketchPoints.add(adsk.core.Point3D.create(-50, -50, 0))

        # prevent this module from being terminate when the script returns, because we are waiting for event handlers to fire
        
        #2) add second sketche
        sketch2 = sketches.add(xyPlane)
        sketch2.name='Fretboard_Contour'
        projections = sketch2.project(line1)
        projections = sketch2.project(line2)
        projections = sketch2.project(line3)
        projectionsP3 = sketch2.project(p3)

        lastFret= sketch2.sketchCurves.sketchLines.addByTwoPoints(adsk.core.Point3D.create(-5, -100, 0), adsk.core.Point3D.create(5,-100, 0))
        coincidentConstraint = constraints.addCoincident(projectionsP3.item(0),lastFret )
        # fb_B = sketch2.sketchDimensions.addDistanceDimension(projections.item(0).endSketchPoint, lineBottom.endSketchPoint, adsk.fusion.DimensionOrientations.VerticalDimensionOrientation, adsk.core.Point3D.create(0, 1, 0))

        adsk.autoTerminate(False)
    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

error is produced by the 76th line :

coincidentConstraint = constraints.addCoincident(projectionsP3.item(0),lastFret )

@grosfaignan .

With this modification, the error was avoided.
