Arbitrary Notches

Arbitrary notches can be used in two different ways:

1. Like a standard notch, that means, positioned by reference to model items. In this case the notch must be described in a local co-ordinate system in a similar way as the standard notches. The difference in use compared to a standard notch is that the notch has a fixed size, that means, it cannot be parameter controlled.

2. The notch is described directly in the co-ordinate system of the panel in the position where it is located. In this case the notch need not be further "positioned". for example, the notch may be created using normal drafting tools. The notch is then converted to a modelling curve that is used as a notch.

In both cases the geometry of the notch should be described so that it reaches well outside the contour where it should be inserted. The contour must be open and have exactly two intersection points with the part contour. Its circulation direction may be arbitrary.

The figure below shows a case where a notch of a special shape has been created along an edge for a couple of penetrating pipes. The contour of this notch has been described directly in the co-ordinate system of the panel.
