BY AREA

Purpose:

This function is used to and delete all geometric information inside or outside a restricting area, defined by a rectangle, polygon or as a general closed area in the current drawing. Note that contours intersected by the restricting area will be cut up prior to deletion.

Instructions:

1. In the Edit menu, click Delete, then By Area.

2. The subpicture to treat is selected by user. Click All to treat the whole drawing.

3. The restricting to define will divide the geometric information in the subpicture (or the whole drawing) in two parts. Before proceeding, the user must decide what part to keep. A multiple choice dialog shows up with the two alternatives:

   • Keep inside

   • Keep outside

4. The way of defining the restricting area is selected by user from a multiple choice dialog:

   • Rectangle/Polygon

   • General Area

5. Finally, the restricting area is defined by user. After the restricting area has been defined and confirmed by user, all geometric information inside or outside the area is now captured and deleted.

   Note: It is possible to capture also invisible geometry (geometry that are marked as invisible and geometry that are not shown because its layer is hidden). This option is controlled by the Drafting Default keyword ALLOW_RESTRICT_INVISIBLE_GEOM. This condition can also be enabled/disabled in this context by clicking the Options button in the multiple choice dialog presenting the restrict conditions Keep inside and Keep outside. Clicking this button will swap the "capture invisible geometry" condition (from "invisibles ignored" to "invisibles captured" and vice versa).

Options:

None.

Result:

Geometric information in the drawing will be deleted according to user's action.
