Using the Clip Tool

By Chris 'autolycus' Bokitch

Clip planes let you make a precise cut in a solid, dividing it into two pieces. You then have the option of keeping one or both of the resulting two solids. You may find using clip planes quicker and more efficient than carving or vertex manipulation.


  1. Select the object to be clipped. (fig. 1)
  2. Select the Clip Plane button on the MapTools toolbar.

      Note: You can cycle through the clip modes by clicking on the clip plane button, or by pressing Shift-X (fig.2, 3, 4). You can move both points of the clip line by holding CTRL and dragging one point of it.

  3. Drag a line across the selected object. (fig. 2) This is the clip line. The part of the object to be kept will be highlighted in thick white lines.
  4. When you are satisfied with the resulting object, press Enter to perform the clip. (fig. 5, 6)

Worldcraft 3.3 adds a feature to display the size of the solid area of the clipped brush. This is useful if you're trying to clip a brush to an exact size.


To toggle this on and off, have a 2D view in focus and press the o hotkey.
