CUTOUT

Purpose:

To enable a user to incorporate a 'cut out' shape into a geometric entity definition, (line, arc, contour, spline, ) based on an intersecting geometric entity of the required shape, and with each entity being currently defined and positioned in a 2-D drawing

Instructions:

1. In the Modify menu, click Trim, then Cutout.

2. With the cursor select the receiving entity, (line, arc, or spline) in which the 'cut out' geometry is to be incorporated. The selected entity may have an open or closed definition.

3. With the cursor select the geometric entity that contains the definition of the cut out. This geometric entity may also have an open or closed form. This 'cut out' entity must intersect the receiving entity at least two points, this being the typical case. If the system determines that there are more than two intersection points then the user is request to cursor select the required two points.

4. The system will add the cut out geometry to the receiving entity, automatically making a gap, and highlight the result for the user to accept or reject. If part of the cut out geometry entity is not added to the receiving entity then it is deleted, when shown in the highlighted form.

Options:

When either or both the receiving and 'cut out' entities are of closed contour form, then the user can control the selection of the relevant portions of each of the entities by accepting or rejecting the highlighted arrangement shown.

Result:

A 'cut out' contour definition is incorporated into the selected contour entity definition, displayed on the screen and stored in the drawing file.
