Command Options
Boundaries |
Description |
Pick points in boundary |
Specifies the closed areas in which to place the boundary; temporarily dismisses the dialog box, and then prompts you at the command bar: Pick a point to define a boundary or hatch area or [Select entities/Undo]: - (enter an option):
Notice that BricsCAD highlights draws the boundary, allowing you to preview it. The prompt repeats, allowing you to choose additional areas, entities, or undo the selection. When done selecting areas, press Enter return to the dialog box. |
Boundary tolerance |
Determines the largest gap that can exist in the boundary for the program to consider the area closed; enter a value:
|
Boundary set |
Specifies where BricsCAD should search for entities that make up the boundary. Select an option from the droplist:
|
New |
Creates a new selection set of entities that make up the boundary; temporarily dismisses the dialog box, and then prompts you at the command bar: Select entities - (use any selection method to choose one or more entities) The prompt repeats, allowing you to choose additional entities. When done selecting entities, press Enter to return to the dialog box. |
Retain Boundaries as |
Specifies how to handle the boundary entity; currently, the only option is to make the boundary out of a polyline, and then retain the boundary after you exit the dialog box. |
Islands |
Determines how the boundary search algorithm treats "islands", boundaries that are found inside the boundary. Choose one:

Procedures
Grips Editing
Boundaries can be edited directly through grips:
-
Select the boundary. Notice that it has many grips.
-
Drag a grip to stretch the boundary.
