Boolean operation

As soon as you select the BOOLEAN OPERATION function, the properties bar appears.

Type of 3D operation

Section

The result is the section (intersection) of the specified object.

Join

The objects specified are joined.

A minus B

The objects are subtracted.

Associative

When enabled, the result is associatively linked with the starting definition. If a starting definition is changed, the result automatically updates.

The boolean operation creates a new object. The new object recieves the colour/VisMat from object-A and the classification information of the group, class and level.

Define boolean operation

Workshop

1. The basis for this example is two boxes inside each other. Draw two rectangles and use them to define boxes.
2. Then click on the BOOLEAN OPERATION function.
   Select the option MINUS in the property bar.

   Please click definition A (enter = End)
   Use the mouse to click on the larger of the two boxes and then confirm with  Enter .

   Please click definition B (enter = End)

3. Now the object that is to be removed can be specified. Click on the smaller box and confirm this with  Enter .

The SECTION option produces the following result.

The JOIN option produces the following result.

Tip

When selecting the different definitions "A" or "B", you can select as many objects as you wish, before ending the process with  Enter .

Tip

Please note: Some situations might lead to problems if the involved objects have a surface in common. In such cases, a small overlap can be helpful.
