Displaying Contact Points On Elements

You can display contact points on elements and modify their values.

These handles appear:

either by clicking the command in the App Options panel as illustrated in this task
or by selecting the option in Me > Preferences > App Preferences > 3D Modeling > Styling > FreeStyle Shape Design, General tab, Display section.

Once they appear, their behavior is identical regardless of the chosen interface style.

Before you begin: Open an existing 3D shape.

From the Creation section of the action bar, click Blend Surface .
Select an edge on each surface.
The blend surface is computed.
In the App Options panel, click Contact Points .
handles are displayed on the connection, allowing you to interactively define the blend limits by simply sliding them along the boundaries.

You can edit the contact points by right-clicking them and selecting Edit. The Tuner dialog box opens to let you key in a new value, in percentage of the total boundary.
