Vertex : Scanned Point

Ref.Point : User made Ref.Point 

Point On Surface : any point on NURBS surface

Point On Curve : any point on NURBS Curve

3. The result appears on the lower left side of the workspace window as follows.

Point 1, Point 2, Point 3 are coordinates of three selected points respectively.

Center is the coordinate of the center point of the circle passing through above three points.

Radius is the radius of the circle.

Arc Length is the length of the arc which runs from Point 1 to Point 3 and displayed in blue on the screen.

Note

• Point on Surface option cannot be applied to surfaces without mesh or if rendering never been executed once. Because picking point algorithm uses rendering information. So Point on Surface option can be applied to TRUE COLOR display mode with rendering information only.
