Modify shapes

When drawing a segments or shapes that intersect with an existing shape, you can modify the existing shape such as splitting or combining.

Split shapes

You can split shapes using the Polygonal Shape Creation tool (S). When the first and last vertex are snapped to an edge or vertex of the same shape, and the entire line is contained in this face, it is automatically split into two parts as shown in the following image:

Combine shapes

To combine shapes into one shape, click any of the shape creation tools and draw a shape that snaps to an existing shape.

The following image shows the combining of intersecting shapes:

Note:

For both of these options, ensure the following conditions are applied:

• The Shapes option under Snapping is turned on in the shape creation tool options.
• The Force New Shape option is turned off.
