Working with Keep-in/Keep-out Areas
A Keep-in area is a polygon that you set so that when objects are moved
outside of it, a DRC error is generated. Conversely, a Keep-out area
generates a DRC error when objects are moved into it.
Placing Keep-in/Keep-out Areas
The Keep-in/Keep-out properties dialog box lets you place a polygon that
will act as either a Keep-in or a Keep-out area. By default, a Keep-out is
placed.
Complete the following steps to add a restricted area:
1. Choose Place»Keep-in/Keep-out Area.
2. Left-click all points that are to define the polygon, ending with the
starting point.
Viewing and Editing Keep-in/Keep-out Properties
To display the Keep-in/Keep-out properties dialog box, select the desired
keep-in/out and select Edit»Properties. (The Keep-in/out layer must be
active).
The Keep-in/Keep-out properties dialog box consist of two tabs:
Attributes and Keep-in/keep-out.
The Attributes tab allows you to edit the properties of the selected area.
For more information on editing properties in the Attributes tab, refer to
the Attributes section of Chapter 4, Working with Parts.
The Keep-in/Keep-out tab lets you set specific parameters.
Complete the following steps to set Keep-in/Keep-out parameters:
1. In the Type box, select either Keep-out or Keep-in.
2. In the Layers box, check the layers to which the Keep-in/out applies.
