Specifying Relimiting Elements

The guiding contour can be restricted by means of Start and Stop relimiting elements. The tool can be positioned In, On or Out with respect to a relimiting element. You can select a point or a curve as relimiting element.

You can use points created "on the fly" but be aware of the following recommendation. By deciding to use explicitly "on the fly" created points as limit, you discard any associativity with the part. Such points are only known via their XYZ coordinates. Since they are not part of the same Product as the part, we cannot ensure that their location is kept for each and any transformation applied to the part.

Basic scenario where points are created on the fly on part1, then part1 is mounted on the machine once is supported. But Advanced scenario with several transformations (e.g. create the points on the fly on part1, mount part1, change part1 to part2, mount part2) are not supported. The usage of "on the fly" created points should be limited to machining scenario where there is no move, nor change of the part.

If you expect the limiting points to always follow the part location, the creation of CATPoint in the same product as the part is the correct methodology.

If you do not look for part associativity, a fast way to specify relimiting points is to right-click the guiding contour area in the sensitive icon of the dialog box and set the Relimitation point detection contextual command.  When you select a guiding contour, its extremities will be used as relimiting elements.

Note that a relimiting point can be created anywhere along the guiding contour by means of the Add relimiting point contextual command. Just right-click the relimiting element area in the sensitive icon of the dialog box and select any position along the guiding contour.
