Creating compounds

Compounds provide a flexible approach to creating a variety of shapes from separate objects using Boolean operations.

Unlike joining objects, creating a Compound is a non-destructive process. This means a Compound can be added to, or broken apart, at any time. Objects within the Compound can also be removed and modified without restriction, if and when desired.

Objects within a Compound interact with each other depending on their individual compound mode. This mode can be changed at any time; each mode can be previewed in real time on selection.

Compound modes

There are various operations available (illustrated as before and after):

Add—expands Compound by adding the object's area to all objects below; the colour of the lowest object is used. This is the default mode.

Add

Subtract—reduces Compound by removing overlapped areas of the lowest object. All other selected objects are discarded.

Subtract

Intersect—modifies Compound by only showing overlapping areas of selected object and objects below.

Intersect

Xor—modifies Compound by creating a composite shape, with transparent areas where object overlaps with objects below.

Xor

Geometry To create a Compound:
  1. Select multiple objects.
  2. On the Move Tool's context toolbar, tap Geometry. A list of entries will appear.
  3. Long-press on Add, Subtract, Intersect or Xor.

The compound will be created as a Compound layer entry on the Layers panel, containing the original objects.

Layer Options To change the compound mode subsequently:
  1. On the Layers panel, expand the compound and select an object other than the bottommost.
  2. From Layer Options, select an alternative Compound mode.
To add an object to a Compound:

The object is included in the Compound using the default Add mode.

To remove an object from a Compound:
  1. On the Layers panel, expand the compound's entry.
  2. Drag the object's entry from inside the compound to a new stack position outside the compound.
