2D Boolean Operations

(Available in all DoubleCAD Variants)

Default UI Menu: Modify/2D Boolean Operations

Ribbon UI Menu:

Boolean operations use two or more existing 2D objects to create a new object. Objects can be combined, subtracted, and intersected. You can display the Boolean and Facet toolbar by right-clicking in any toolbar area and selecting Boolean and Facet.

The object created as a result of a 2D Boolean operation is considered a region. You can use the Selection Info Palette to determine the type of any object or objects you select. Selection order can be important, because the properties (color, layer, etc.) of the resulting region are taken from the first object selected.

2D Add

Default UI Menu: Modify/2D Boolean Operations/2D Add

Ribbon UI Menu:

Combines 2D closed objects to form one region. Any overlap between selected objects is removed.

Note: The results of 2D Add are identical to using Format / Create Region.

  1. Select two or more closed objects to combine.

img

  1. Select Finish Selecting from the local menu or Inspector Bar.

img

The resulting object is one region. You can verify this by selecting the region.

img

The selected objects do not have to overlap. If you combine non-overlapping objects, they will still be combined into one region. You can verify this by selecting the region.

2D Intersect

img

Default UI Menu: Modify/2D Boolean Operations/2D Intersect

Ribbon UI Menu:

img

Produces the intersection of two or more closed 2D objects, to form a region. Select two or more objects whose intersection you want to obtain.

img Select Finish Selecting from the local menu or Inspector Bar.

img

The resulting object is one region. You can verify this by selecting the region.

img You can select more than two objects, but they must all intersect one another.

img

Note: If you select objects that do not overlap, the result will be no objects (original objects deleted).

2D Subtract

img

Default UI Menu: Modify/2D Boolean Operations/2D Subtract

Ribbon UI Menu:

img

Subtracts one or more objects from one or more objects, to form one region.

  1. Select one or more objects to subtract area from.

img

  1. Select FinishSelecting from the local menu or Inspector Bar.

  2. Select one or more objects to subtract from the previously selected objects.

img

  1. Select Finish from the local menu or Inspector Bar. The second group of objects is removed from the first group.

img

  1. The resulting object is one region. You can verify this by selecting the region.
