Vector3d -> Point3d ?
-
Hi all, another simple question.
I would like to define a point by another point + a vector. However, in my Ruby, pt + vec returns another vec object, rather than a pt. So, is there a simple way to convert this returning vec to pt, cos I guess they all belong to array right? Thanks!

point3D.offset(Vector3D) ?
(thank you Didier !! ) -
NICE
! Thank you all!

Adding a Vector3d to a Point3d should return a Point3d, however the converse is not true. Are you sure of the types of the objects you are "adding"?

No! Point3d's and Vector3d's are distinct classes and not related to Arrays. However, SketchUp does add a few methods of "convenience" to the Array class, so that (in some cases) you can use an Array "as if" it were a Point3d or Vector3d.
pt = Geom;;Point3d.new v = Geom;;Vector3d.new (1, 0,0) pt + v ==> Point3d(1, 0, 0) v + pt ==> Error; #<ArgumentError; (eval);45;in `+'; Cannot convert argument to Sketchup;;Vector3d> v + [1,2,3] ==> Vector3d(2, 2, 3)In this example, the Array ([ 1, 2, 3] ) is made into a Vector3d before the '+' operation.

Thank you Jim!
BTW, how can I change my profile? I have no picture nor description for myself. -

That does. I guess I misunderstood '+' from the start. Thanks again.
