To Establish a Connection while Creating a Surface
1. Make sure that the Surface tab is open.
2. Move the pointer over a connection symbol, right-click, and choose a connection type from the shortcut menu:
G0 - Position
G1 - Tangent—Available only when the boundary has a neighbor.
G2 - Curvature—Available only when the boundary has a neighbor.
G3 - Acceleration—Available only when the boundary has a neighbor, and when the surfaces are boundary surfaces or loft surfaces.
Normal—Available only for a planar boundary.
Draft
If you choose G0 - Position or Normal, the connection is created.
3. If you choose Draft, select a draft reference. The connection is created with a default draft angle of 10 degrees.
4. To change the draft angle, double-click the value, type a new one, and press ENTER. The draft angle is modified.
