Modifying the Template Geometry

In order that the template can penetrate a panel on which it is positioned when instanced in a design, it must include a second negative box owned by the TMPL. A negative box owned by the positive box will not have the required effect, which is why we did not create it in the original equipment.

Exercise continues:

1. The new NBOX must be created below the TMPL. To achieve this, you must first navigate to the TMPL in the Design Explorer. The easiest way to do this is to check the Template Browser's Navigate on selection checkbox and then reselect the TMPL in the browser list. This element will become current in the Design Explorer automatically.

   Alternatively, if you have the Draw List window open, you can choose the Navigate To option from the popup menu that appears.

2. From the Design Templates Application menu, select Create > Primitives. Create a Negative Box.

3. Set the Y-length to 950, X-length to 450 and Z-length to 100.

4. Leave the Orientation at its default setting.

5. We want to position the new NBOX so that its upper face is coplanar with the lower faces of the existing BOX and NBOX. To achieve this, we must move it down by half its Z-length, so set the Position to Y 0, X 0, U 50.

6. Set the Name to /Panel-pene.

We have now completed the required design template geometry, as illustrated in the diagram near the start of Creating a Simple Template. In the next chapter we will see how to allocate properties and rules to the template, so that its geometry may be parameterized and adjusted to suit specific use in design contexts.
