I worked CRhinoGetPoint for drawing some points or spheres on the mesh.
Now, I have a problem
I want to delete or move a object when the cursor is on the object.
Can I know whether the cursor is on the some object or not in the event OnMouseMove?
The example is below.
If the cursor is on the Mesh surface #1 and the mouse left button is pressed, it will draw a sphere on the mesh surface #1.
But, if the cursor is on the some objects, Mesh sphere #1 ~ N, I will stop to draw the sphere or delete this object.
