Match Scale syntex

[Anonymous]

Hi,
I am new to max script.
I have take sphere with 50.0 radius.
Spline circle take with 25.0 radius then convert it to editable spline.
I want to match scale of circle to the sphere.
Can anybody help in find out proper syntax for this ?

Thanx in advance

something like

s = sphere radius:50
c = circle radius:25
convertToSplineShape c

------------------
c.scale = 

-- or ------------
bb = c.max - c.min
c.scale.x *= s.radius / bb
c.scale.y *= s.radius / bb

With all the usual caveats about not scaling at the object level. May not be relevent in this specific case but it's worth pointing out.

I know what you mean, but did you have better idea for scaling shapes?
(i exclude processing knots as option as its too complicated)

If that help, here is a script online "Resize Splines From First":

That would be the "proper" way I suppose, but indeed complicated.
An alternative might be to use ResetXForm<node> then CollapseStack<node> - the equivalent of what would normally be done in the viewports.

I have tried this script:


s = sphere radius:50
c = circle radius:25
convertToSplineShape c

bb = c.max - c.min
c.scale.x *= s.radius / bb
c.scale.y *= s.radius / bb

But spline shape not matched remain as it is.

c.scale = works but for unknown parameter mesh
what should i do?

Thank you

Yep, there is little maths mistake, next is correct:

c.scale.x *= (s.radius * 2) / bb
c.scale.y *= (s.radius * 2) / bb

and what "unknown parameter mesh" means? If your object is strored in variable then access it '.scale' prop using varName.scale, if you work on selected object then selection.scale

Thank you so much
