Working with Objects

Combining Objects

Two or more objects can be combined using the Combine operations. These operations work with wall panels, openings, floors, ceilings and terrains. You can only combine objects of the same type. Depending on the size and location of the original objects and also on the used operation, the result can consist of one or more new objects. In order to combine objects, select two or more of them. Then bring up the context menu and choose a command from the Combine category. The following subsections demonstrate how you can combine 2D representations of objects.

The app supports the Union, Subtract, Intersect, Exclude and Divide operations. They take effect when the original objects overlap partially or completely. If the original objects don't overlap, they will remain unchanged. These operations don't work with objects that are located on different levels (e.g., ceilings that belong to different stories).

Union

The result of Union is an object that includes the area of all original objects. The created object takes on the properties (e.g., material) of the original object that had the biggest area.

Subtract

The result of the Subtract operation is a part of the first selected object that was not covered by any other object.

Intersect

The result of the Intersect operation is an object that includes only the area where all of the original objects overlap. The created object takes on the properties (e.g., material) of the original object that had the biggest area.

Exclude

The result of the Exclude operation is one or multiple parts of the original objects where they did not overlap each other.

Divide

The Divide operation doesn't actually combine objects but splits them into parts. The objects' outlines act as cut lines. The result of the Divide operation are parts of the original objects that take the same area that was taken before. The created objects retain properties of the original objects.

In the image above, we created three objects. The green rectangle in the middle was part of the original green area.
