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.
5. To add or change the reference for a surface connection:
a. Click the Constraints tab.
b. In the Connection table, select the row of the connection to edit.
c. Click the Connection reference collector to activate it, and select a surface or plane reference.
d. If needed, click 
to reverse the connection:
to reverse the connection:▪ G0, G1, G2, and G3 connections—Switches between the follower surface and the leader surface, so the leader will be the follower, and the follower will be the leader.
▪ Normal connections—Reverses the normal direction.
Surface connections cannot be edited in Reparameterization mode.
