Frequently Asked Questions (FAQs)
Creating Curves on Database Entities
A curve created on a database entity (database curve, surface, or quilt) can be a segment that has a slope defined by a Catmull-Rom, Akima, or Bezier control algorithm. Please refer to the following exercises to see how these slopes are defined.
There are two ways to create connectors on database entities: by hand and automated.
By Hand Curve Creation
Automated Curve Creation
There are now four connectors defining the four edges of the database surface. However, the connectors are not dimensioned.
Now the connectors are dimensioned. But you can also apply a Connector Dimension or Average Δs before creating the connectors by going to the Defaults tab.
Editing Control Points
There are two quick ways to edit a control point location before a connector is saved by using the Apply or OK commands. The first method simply requires that you move your cursor over the control point in the display window until it highlights in orange. Hold the left mouse button depressed while you move the point to a new location then release the left mouse button. The second method requires that you select the control point by holding the Ctrl key while left clicking on the point. The control point will become highlighted and the XYZ field in the Point Placement frame will update to contain its current coordinates; change the values and hit Enter to change the control point location.
