DIRECT MODELING METHODS
Direct modeling modifies the geometric model by modifying its components. A geometric model at any stage can be used: it can be a template or a finalized model. Direct modeling methods can modify either all elements of a geometric model or its specific groups. For instance, a body face group can be moved relatively to other body faces, or it can be replaced with equidistant faces or deformable faces. A new body can be constructed from the selected group of faces. The selected fillets or characteristic features can be deleted from the geometric model, for instance, holes or raised portions.
