How to Subtract Shapes in CorelDRAW

This article provides an overview of how subtraction operations function in CorelDRAW, covering the specific tools used to cut overlapping vector objects, the differences between trimming and minus operations, and a clear step-by-step guide to applying them to your vector artwork.

Understanding Subtraction in CorelDRAW

In CorelDRAW, subtraction is not a standalone tool icon on the main toolbar; rather, it is performed using vector shaping operations (Boolean operations). These commands allow you to use the overlapping area of one object to cut away or subtract from another object.

CorelDRAW provides three primary commands to achieve subtraction:

  • Back Minus Front: Removes the front (top) object entirely and subtracts its overlapping shape from the back (bottom) object.
  • Front Minus Back: Removes the back (bottom) object entirely and subtracts its overlapping area from the front (top) object.
  • Trim: Cuts out the shape of an object from another object without necessarily deleting the source object, providing flexibility depending on whether "Source Object" or "Target Object" retention is enabled.

How to Use "Back Minus Front" and "Front Minus Back"

These are the fastest one-click subtraction commands when you want to remove the cutting shape automatically.

  1. Arrange the Objects: Place the cutting shape over the base shape. Verify their stacking order (which object is in front or behind) via the Objects docker or by right-clicking and choosing Order.
  2. Select Both Objects: Use the Pick tool to drag a marquee selection over both objects, or hold Shift and click each object.
  3. Apply the Subtraction:
    • Look at the interactive Property Bar at the top of the workspace.
    • Click Back Minus Front to cut the top object out of the bottom object.
    • Click Front Minus Back to cut the bottom object out of the top object.

How to Use the Trim Command

The Trim command offers greater control, especially when you need to subtract a shape repeatedly without losing the original cutting object.

  1. Using the Property Bar:
    • Select the cutting object first, hold Shift, and select the target object.
    • Click the Trim icon on the Property Bar.
    • The shape of the first object is carved out of the second object, leaving both objects on the canvas.
  2. Using the Shaping Docker:
    • Go to Object > Shaping > Shaping to open the Shaping Docker panel.
    • Select Trim from the drop-down menu.
    • Check or uncheck Source Object and Target Object to choose whether the original shapes remain after the operation.
    • Select your cutting shape, click the Trim button in the docker, and then click on the target object you want to cut.

Common Use Cases

  • Creating Cutouts and Holes: Carving text or geometric shapes out of solid backgrounds for stencil effects.
  • Logo Design: Creating complex negative space designs by slicing intersecting curves.
  • Joinery and Manufacturing: Designing interlocking parts for laser cutting and CNC routing by creating exact matching clearances.
