Sphere object creation (usage of PutSphereData method)

[Maxim-CADman77]

I'd like to know how to create Sphere object with iLogic.

I guess I need to use PutSphereData method, right?

I tried the below code

Dim oInv As Inventor.Application = ThisApplication
Dim oSph As Sphere = Nothing
Dim dRad As Double = 10

Dim crds(2) As Double
crds(0) = 0
crds(1) = 0
crds(2) = 0
oSph.PutSphereData(crds, dRad)

MsgBox(oSph.Radius,,"Sphere Radius")

I expected to get back "10" with Message Box but got "Object reference not set to an instance of an object" error instead.

What I' missing?

Because you never create the Sphere object. Use TransientGeometry.CreateSphere Method first
