Creating a Scrap Partition

This task shows you how to automatically compute scrap elements (Cut parts of the sheet of metal that are discarded) using the addendum surface and the cutting lines.

Open ScrapPartition_InitP1.CATPart from the samples directory.
You can see the result in ScrapPartition_EndP1.CATPart.

Click Scrap Partition in the Process Part Separation toolbar.
Select the Part Geometry (one or several surfaces to cut -Full Addendum in our example).

Select the Splitting Elements.

They can be:
A 3D curve projected on the surface to cut.

A 2D Curve that defines a plane.

3D surfaces intersecting the surfaces to cut.

Or a trim partition. Each element of the trim partition is used as trim curve.

Select the Scrap Cutters elements (wireframe).
Depending on the geometries inside the sketch that defines the scrap cutters, geometries are extracted and computed with a type (Scrap Hole or Scrap Line). This type can be changed from the contextual menu.
Select the Projection Direction.
By default, the projection is normal to the surface.
Results are listed under Scrap Surfaces.

A Scrap Partition is created under Partition Set in the specification tree
such as the red surfaces below.

It contains Scrap Surface features, with reference features.

A join is computed from the selected surfaces.
A split of the join is computed for each trim curve.
For each computed split, the smallest section is kept and added to the results.
The associated trim curve is displayed under Reference Features.
