Problem with loft after last Fusion update (plugin doesn't work)

Hello everyone,

I use loft in my plugins. After last Fusion update this funcitionality doesn't work as before, I mean clients get errors, no matter loft is through profiles with rails or not. Making loft by UI works (but for rails I need to turn off "Chain selection" checkbox).

I prepared sample script to show one of the case. There's no error messages but lofts are not as expected:

It seems that loft starts from middle profile

Script:

import adsk.core, adsk.fusion def run(context): app = adsk.core.Application.get() product = app.activeProduct design = adsk.fusion.Design.cast(product) rootComp = design.rootComponent # Example 1 - same size of profiles but different Z sketch1 = rootComp.sketches.add(rootComp.xYConstructionPlane) # First profile p11 = adsk.core.Point3D.create(0, 2, 0) p12 = adsk.core.Point3D.create(2, 0, 0) p13 = adsk.core.Point3D.create(0, -1.3, 0) p14 = adsk.core.Point3D.create(-1.8, 0, 0) p15 = adsk.core.Point3D.create(-1.2, 1, 0) sketch1.sketchCurves.sketchLines.addByTwoPoints(p11, p12) sketch1.sketchCurves.sketchLines.addByTwoPoints(p12, p13) sketch1.sketchCurves.sketchLines.addByTwoPoints(p13, p14) points = adsk.core.ObjectCollection.create() points.add(p14) points.add(p15) points.add(p11) sketch1.sketchCurves.sketchFittedSplines.add(points) # Second profile p21 = adsk.core.Point3D.create(0, 2, 4) p22 = adsk.core.Point3D.create(2, 0, 4) p23 = adsk.core.Point3D.create(0, -1.3, 4) p24 = adsk.core.Point3D.create(-1.8, 0, 4) p25 = adsk.core.Point3D.create(-1.2, 1, 4) sketch1.sketchCurves.sketchLines.addByTwoPoints(p21, p22) sketch1.sketchCurves.sketchLines.addByTwoPoints(p22, p23) sketch1.sketchCurves.sketchLines.addByTwoPoints(p23, p24) points = adsk.core.ObjectCollection.create() points.add(p24) points.add(p25) points.add(p21) sketch1.sketchCurves.sketchFittedSplines.add(points) # Third profile p31 = adsk.core.Point3D.create(0, 2, 10) p32 = adsk.core.Point3D.create(2, 0, 10) p33 = adsk.core.Point3D.create(0, -1.3, 10) p34 = adsk.core.Point3D.create(-1.8, 0, 10) p35 = adsk.core.Point3D.create(-1.2, 1, 10) sketch1.sketchCurves.sketchLines.addByTwoPoints(p31, p32) sketch1.sketchCurves.sketchLines.addByTwoPoints(p32, p33) sketch1.sketchCurves.sketchLines.addByTwoPoints(p33, p34) points = adsk.core.ObjectCollection.create() points.add(p34) points.add(p35) points.add(p31) sketch1.sketchCurves.sketchFittedSplines.add(points) # Create loft loftFeatures = rootComp.features.loftFeatures loftInput = loftFeatures.createInput(adsk.fusion.FeatureOperations.NewBodyFeatureOperation) for ip in range(sketch1.profiles.count): loftInput.loftSections.add(sketch1.profiles.item(ip)) loftInput.isSolid = True loft = loftFeatures.add(loftInput) # Example 2 - different sizes of profiles sketch2 = rootComp.sketches.add(rootComp.xYConstructionPlane) xShift = 10 # First profile p11 = adsk.core.Point3D.create(0 + xShift, 2, 0) p12 = adsk.core.Point3D.create(2 + xShift, 0, 0) p13 = adsk.core.Point3D.create(0 + xShift, -1.3, 0) p14 = adsk.core.Point3D.create(-1.8 + xShift, 0, 0) p15 = adsk.core.Point3D.create(-1.2 + xShift, 1, 0) sketch2.sketchCurves.sketchLines.addByTwoPoints(p11, p12) sketch2.sketchCurves.sketchLines.addByTwoPoints(p12, p13) sketch2.sketchCurves.sketchLines.addByTwoPoints(p13, p14) points = adsk.core.ObjectCollection.create() points.add(p14) points.add(p15) points.add(p11) sketch2.sketchCurves.sketchFittedSplines.add(points) # Second profile p21 = adsk.core.Point3D.create(0 + xShift, 4, 4) p22 = adsk.core.Point3D.create(4 + xShift, 0, 4) p23 = adsk.core.Point3D.create(0 + xShift, -2.6, 4) p24 = adsk.core.Point3D.create(-3.6 + xShift, 0, 4) p25 = adsk.core.Point3D.create(-2.4 + xShift, 2, 4) sketch2.sketchCurves.sketchLines.addByTwoPoints(p21, p22) sketch2.sketchCurves.sketchLines.addByTwoPoints(p22, p23) sketch2.sketchCurves.sketchLines.addByTwoPoints(p23, p24) points = adsk.core.ObjectCollection.create() points.add(p24) points.add(p25) points.add(p21) sketch2.sketchCurves.sketchFittedSplines.add(points) # Third profile p31 = adsk.core.Point3D.create(0 + xShift, 3, 10) p32 = adsk.core.Point3D.create(3 + xShift, 0, 10) p33 = adsk.core.Point3D.create(0 + xShift, -1.95, 10) p34 = adsk.core.Point3D.create(-2.7 + xShift, 0, 10) p35 = adsk.core.Point3D.create(-1.8 + xShift, 1.5, 10) sketch2.sketchCurves.sketchLines.addByTwoPoints(p31, p32) sketch2.sketchCurves.sketchLines.addByTwoPoints(p32, p33) sketch2.sketchCurves.sketchLines.addByTwoPoints(p33, p34) points = adsk.core.ObjectCollection.create() points.add(p34) points.add(p35) points.add(p31) sketch2.sketchCurves.sketchFittedSplines.add(points) # Create loft loftFeatures = rootComp.features.loftFeatures loftInput = loftFeatures.createInput(adsk.fusion.FeatureOperations.NewBodyFeatureOperation) for ip in range(sketch2.profiles.count): loftInput.loftSections.add(sketch2.profiles.item(ip)) loftInput.isSolid = True loft = loftFeatures.add(loftInput)

When I do this by UI it works:

Order is ok

What should I do to make this work by API?

There's also another problem in case of using rails because I cannot find an equivalent of "Chain Selection" in API. Is it accessible or is it performed on much higher level?

Solved. If you have similar problems, try to make each profile in dedicated sketch (no matter profile is CW or CCW). If you need rails they also should be in a separate sketch.
