"can you post how you solve it  "

"Hi Liviu, A is of type System.Object and therefore you shouldn't be able to use methods or operators on it. You should declare a private variable to contain your data and only assign it to A when you're done calculating it. -- David…"

"Hi Liviu, You need to create a PolylineCurve or use the ToNurbsCurve() method on your Polyline instance. -- David Rutten david@mcneel.com Poprad, Slovakia"

"nevermind, I got it"

"Obviously, inside a VB component"

"I solved, the rail curve was flipped"

"Off topic: I'm having a problem when trimming a list of curves with a closed Brep. Sometimes it doesn't give the correct in-curves and out-curves and I have to bake the geometry, trim it in rhino and reference it back into grasshopper. Any…"

"All intersection stuff is in the Rhino.Geometry.Intersect namespace. We've done this as it otherwise wouldn't be obvious whether to put Curve|Brep intersections on curves or breps.   -- David Rutten david@mcneel.com Poprad, Slovakia"

"I need the curve | curve intersection in the vb component, I can't find it under curve methods."

"RhinoCommon offers quite a few methods here. You can intersect line segments very quickly, you can use curve|curve intersection (slower, but works on all curves), you can test whether points are inside a closed curve region etc. You'll need to…"

"Hi David,   Thanks. One more thing. These points define some polygons that inflate. I need something like collision detection; something like curve - curve intersection but also in the VB component."

"How are the polygons defined?   -- David Rutten david@mcneel.com Poprad, Slovakia"

"Hi Liviu,   translating points is quite easy:   Dim pt As New Point3d(2,4,8) Dim motion As New Vector3d(1,-6,0) pt += motion   If you want to transform the point (something more complex than a simple translation) then you can do…"

"And another thing: how to obtain the intersection of several polygons in the VB component?"
