Trim or break intersecting faces

Use Intersect Faces to trim or break intersecting faces. Perform in conjunction with Extend Faces to ensure that faces intersect.

  1. Open a file that contains surfaces.
  2. If necessary, right-click the surfaces in the browser and select Copy to Construction in the context menu to copy the required surfaces to the construction environment.
  3. In the browser, double-click the Construction folder to open the construction environment.
  4. On the ribbon, click Construction tab Surface panel Intersect Faces .
  5. Choose one of the following methods to select surfaces:

    Trim: Click Trim, and then select two intersecting surfaces, making sure to select the area you want to keep. Surfaces are trimmed to the intersection.

    Break: Click Break, and then select two intersecting surfaces. The surfaces are split at the intersection. All are placed in the same browser group.

    Note: If more than two surfaces intersect, only two are trimmed at one time.
  6. Continue to click Trim or Break and select surfaces in the graphics window.
  7. When finished, click Done.
Note: You can use multiple surfaces to trim. For example, you can stitch two connected surfaces together into a quilt. Select Intersect Faces, and click the quilted body. Select a surface that intersects the quilt to create two trimmed bodies.
