Hi,
I was expecting that a boundingbox build from profile's curves formed with a spline was adjusted to the curved.
What I'm getting is a boundingbox that is both wider and taller than the spline.
I was also able to reproduce the same issue with manual-drew splines (both fitted and control point splines).
Should it be considered a BUG? Or what the gap between the curve and boundingbox means?
On this image I draw the box with the boundingbox build from profile curve's boundingbox property:
When I draw another box in other sketch with the sketch-curve's boundingbox property I got a box that is adjusted to the spline:
I build the following script is someone want to reproduce the error on its environment (just run it on a empty design):
def profile_loop_boundingbox_test() -> None:
# 1. Create a XY-sketch and a spline on it
sk1 = root.sketches.add(root.xYConstructionPlane)
sk1.name = 'spline'
ctrl_points = [
[1, 1, 0],
[9, 2, 0],
[2, 7, 0],
[1, 1, 0],
]
knots = [0,0,0,0,1,1,1,1]
nc = adsk.core.NurbsCurve3D.createNonRational(
[adsk.core.Point3D.create(*pts) for pts in ctrl_points],
3,
knots,
False)
sfs = sk1.sketchCurves.sketchFixedSplines.addByNurbsCurve(nc)
#2. Create a second sketch and draw a box with profile curves's boundingbox
sk2 = root.sketches.add(root.xYConstructionPlane)
sk2.name = "profile curves-boundingbox"
for profile in sk1.profiles:
profile_loop_n = 0
for profile_loop in profile.profileLoops:
profile_loop_n += 1
bb: adsk.core.BoundingBox3D = None
profile_curve_n = 0
for profile_curve in profile_loop.profileCurves:
profile_curve_n += 1
if bb:
bb.expand(profile_curve.boundingBox)
else:
bb = profile_curve.boundingBox.copy()
skt_lines = sk2.sketchCurves.sketchLines.addTwoPointRectangle(
bb.minPoint,
bb.maxPoint)
for skt_line in skt_lines:
skt_line.isConstruction = True
app.log(f'{profile_loop_n=} {profile_curve_n=}')
#3. Create a third sketch and draw a box with profile sketchcurve's boundingbox
sk3 = root.sketches.add(root.xYConstructionPlane)
sk3.name = "profile sketchEntities-boundingbox"
for profile in sk1.profiles:
for profile_loop in profile.profileLoops:
bb: adsk.core.BoundingBox3D = None
for profile_curve in profile_loop.profileCurves:
if bb:
bb.expand(profile_curve.sketchEntity.boundingBox)
else:
bb = profile_curve.sketchEntity.boundingBox.copy()
skt_lines = sk3.sketchCurves.sketchLines.addTwoPointRectangle(
bb.minPoint,
bb.maxPoint)
for skt_line in skt_lines:
skt_line.isConstruction = True
