To join two or more objects into one object, use the Layout > Merge Polygons > Union command. The new object has the name, color, boundary, and material assignment of the first object selected. The objects are united at the point of intersection.
- Select the objects you want to join.
- From the Layout menu, select Merge Polygons > Union.
The objects are united.
Union and Intersection operations support using selected objects on multiple layers, and each layer object is operated on separately. However, Subtraction is only allowed if the selected objects are on the same layer. Selected objects may be negative objects.
- If only negative objects are selected, the merge operation is performed the same as with positive objects, but the resulting objects remain negative objects.
- If both negative objects and positive objects are selected:
— Complete the union/intersection/subtraction operation on the positive objects
— Always union the negative objects
— Subtract the negative object result from the positive object result
By default, the objects being joined to the first object selected are not preserved for later use. If you want to keep a copy of the objects being joined to the first object selected, do the following:
- Copy the objects, then paste them back into the design after uniting them.
