Spline normalize 2 _Extend Modifier ( how can I snapshot as spline in maxscript ?)

[majid.adab]

Hello everyone

When I scroll the spinner, I want to fix my modifier to work without interruption.

I wrote this modifier as an extend modifier of normalize_spline2 and for now, I want only to print the number of segments and vertex of the newly normalized spline ( not the baseobject spline ). 

I used many techniques but none of them worked for me. The problem is in the 'copy', 'instance', 'delete', or 'maxops.clonenodes' commands  that I used to copy the spline and then extract data from it. this causes an interruption in the spinner of the modifier.

in the second version, I  used snapshot as a mesh but it will convert spline to mesh so I can not access spline data. 

I would be grateful if anyone help me to fix this. I searched ChatGPT and everywhere for about one week.

Thanks

fn getSplineObjectNumSegments spline_obj spline_index = 
(
	g = (dotnetclass "autodesk.max.globalinterface").instance
	inode = g.COREInterface14.GetINodeByHandle spline_obj.inode.handle
	obj = (inode.EvalWorldState g.COREInterface.Time true).Obj

	i = spline_index - 1
	if i < obj.Shape_.SplineCount_ do
	(
		(obj.Shape_.GetSpline i).Segments
	)
)

You can find more info in the help (sdk help) or/and using #showproperties and #showmethods MXS methods

thank you so much Denis.

it helped me so much.

but I am not very familiar with 'dotnetobject' and 'dotnetclasses' I try to learn it more in the help.

your fn works perfect for splineshapes like circle, Ngon, ....  ( because you used splineshape class ) 
but for lines and shapeobjects it gives and error in line "obj.Shape_.SplineCount_" because .shape is not property of shapeobject class and it is not in showproperties.
Now, I am working on it to fix it for lines and splines too.

thank you so much again.

For which class does it not work? Could you provide an exact example?

   fn getSplineObjectNumSegments spline_obj = 

(

g = (dotnetclass "autodesk.max.globalinterface").instance

inode = g.COREInterface14.GetINodeByHandle spline_obj.inode.handle

obj = (inode.EvalWorldState g.COREInterface.Time true).Obj

sps = 0

for i=1 to numSplines spline_obj do

(

sp = obj.Shape_.getspline (i-1)

sps = sps + sp.Segments

)

print (sps)

)

getSplineObjectNumSegments $

Hi Denis,

exactly the line "sp = obj.Shape_.getspline (i-1) " gives the below error for lines and spline objects.

-- Error occurred in anonymous codeblock; filename: ; position: 328; line: 9
-- Unknown property: "Shape_" in dotNetObject:Autodesk.Max.Wrappers.ShapeObject

but as in the screenshot for circles and Ngons and simple spline does not give error.

Line or Editable_Spline are already ShapeObjects... You can get all the info using built-in MXS methods.

but if we want to practice with MAX .NET:

fn getShapeObjectNumSegments spline_obj spline_index = 
(
	g = (dotnetclass "autodesk.max.globalinterface").instance
	inode = g.COREInterface14.GetINodeByHandle spline_obj.inode.handle
	obj = (inode.EvalWorldState g.COREInterface.Time true).Obj

	bz_shape = g.BezierShape.Create()
	obj.MakeBezier g.COREInterface.Time bz_shape
	
	i = spline_index - 1
	if i < bz_shape.SplineCount do
	(
		(bz_shape.GetSpline i).Segments
	)
)

getShapeObjectNumSegments $ 1

Thank you, Denis.

you are a very expert professional and Helpful man.

I read it in the help of dotnetclass and I guess that I should use .MakeBezier to create it.

but I did not know the syntax and how to write it.

you taught me a very useful and powerful.

many many thanks.
