To Combine Mass Elements Using Boolean Operations

Use this procedure to combine mass elements using Boolean operations.

  1. Select the mass element to which you want to join another mass element.
  2. Selected the desired Boolean operation:
    If you want to… Then…
    combine the total volume of two or more mass elements into a composite object click Mass Element tab Modify panel Boolean drop-down Union .
    remove the common area of one mass element from another click Mass Element tab Modify panel Boolean drop-down Subtract.
    remove non-overlapping portions and create a composite solid from the common volume click Mass Element tab Modify panel Boolean drop-down Intersect.
  3. Select the objects you want to combine, and press Enter.
  4. Enter y (Yes) to erase the original geometry, or enter n (No) to keep the original geometry in the drawing. seoe
    Note: A boolean operation creates a free form mass element. Due to the topological structure of the free form mass element, its facet deviation cannot be changed. The FACETDEV command will have no effect on an existing free form mass element.
