  1. Click OK. The clashes under 0.5” are ignored and no more displayed in the model.
  2. Set the clash tolerance parameters to Above a value > 0.5, as shown in the image below.

Task 2: Ignoring Clashes with Slabs

  1. Orbit the model to a 3D view.
  2. One by one, click on all the slabs; all the clashes with the slabs are highlighted, as shown below.
