Main Steps
Select Curve Step
Allows you to select the curves or edges that define the new curve you want. You can select one or more curves or edges.
Finish/Cancel
This button changes function as you move through the feature construction process. The Finish button constructs the feature using input provided in the other steps. Once you construct the feature, you can edit it by re-selecting the appropriate step on the command bar. The Cancel button discards any input and exits the command.
Selecting a Curve Options
Single Curve
Specifies that the output curve is single curve. If all the input curves are connected at their endpoints, a single b-spline curve is constructed. When this option is cleared, the derived curve is comprised of multiple elements. If the input curves are connected, but not tangent, the output curve will have a minimal amount of curvature added so that a single, smooth b-spline curve is constructed.
Select
Sets the method of selecting the elements that define the derived curve.
Single--Allows you to select one or more individual elements.
Chain--Allows you to select a endpoint connected set of elements by selecting one of the elements in the chain.
Deselect (x)
Clears the selection.
Accept (check mark)
Accepts the selection.
Other command bar Options
Name
Displays the feature name. Feature names are assigned automatically. You can edit the name by typing a new name in the box on the command bar or by selecting the feature and using the Rename command on the shortcut menu.
