| SE_shape_symmetrical_difference | |
Returns the symmetrical difference (logical XOR of space) of two shapes.
LONG SE_shape_symmetrical_difference (const SE_SHAPE primary_shape, const SE_SHAPE secondary_shape, SE_SHAPE tgt_shape);
| primary_shape | A handle to an active shape object |
| secondary_shape | A handle to an active shape object |
| tgt_shape | A handle to a shape object handle |
Returns the symmetrical difference (logical XOR of space) of two shapes as tgt_shape.

• This function works in 2-D space. Resulting shapes won’t have z- or m-values.
• Ignores any CAD data in the source shape and removes any CAD data in the target shape.
• Lines which self-intersect may result in anomalous results. Use with line-line combinations that don’t self-intersect.
