6.1.4.3.2. Arc Extrusion Surface
It allows the user to create an arc-extrusion surface for defining Sphere To Arc Extrusion Contact easily.
6.1.4.3.2.1. Modeling Options
The user can create a surface geometry by the following procedure.
Point, Direction, Point, Angle, Distance
Point: Selects a point to define the arc center.
Direction: Defines an axis direction for generating the arc.
Point: Selects a point to define the starting point of the arc. It is the information on the arc radius.
Angle: Defines an angle of the arc.
Distance: Defines the distance of the extruding length.
6.1.4.3.2.2. Properties
The user can modify the geometry information using the Arc Extrusion Geometry property page.
