help on transform syntax

Hi all, I am trying to rotate a point but I don't know about the good way to write it
I wrote the following code but it doesn't work


Dim p0 As New Point3d(0, 0, 0)
Dim p1 As New Point3d(10, 10, 10)
Dim v1 As New Vector3d(1, 1, 1)

Dim rotate_xf As New Transform
rotate_xf.rotation((Math.PI / 180) * 90, v1, p0)
p1.Transform(rotate_xf)

can someone advice me what to do ?

thx

p1.Transform(Transform.Rotation((Math.PI / 180) * 90, v1, p0))

The Transform class has a bunch of static functions that create Transform matrices. So there's no point in making a New Transform(), you should always use Transform.Rotation, Transform.Translation etc.
