Parametric

 

A parametric design consists of five segments:

•Descending straight line

•Descending curve

•Middle straight line

•Ascending curve

•Ascending straight line

The descending straight line starts from the entry point and the ascending straight line ends at the exit point. The remaining segments pass through or under any control points. Depending on the different control points, a parametric design can be created.

 

Entry or exit point only

If only an entry or an exit point is available, the application itself will design a minimum drill line based on the set values:

If the entry point is on the right or the exit point is on the left, the application will ask if the drill direction should be applied in reverse:

 

Control point(s) only

If only control points are available, the application will design a minimum drill centerline through this point:

 

Entry and exit point

If both an entry and exit point are known, the drill line will begin and end at these points. If the entry point is placed on the right side of the exit point, the drill direction will be reversed. It also takes into account the present control points (only between the entry and the exit points):

 

Maximum radius

If it is set that the maximum radius has to be applied, the application will try to keep the straight lines as short as possible.

 

Outside longitudinal section

It can happen that based on the set values a design would end up outside the Profile View. The application reports this and displays a preview of temporary lines that are removed again with the REGEN command.

After designing, the design is checked immediately for deviations.
