The deformation operations allow a user to perform modification of solid and sheet bodies by various means: skewing, bending, scaling/twisting etc.
When creating deformation operations, a function producing volume deformation of the given body is formed in the model on the basis of parameters specified by the user. This function can be defined over the entire volume of the given body or only its part. Applying this function in a continuous manner deforms the entire volume of this body (or its part). Topology of the deformed part of the body does not change. The number of faces, edges, vertices, etc. remains the same. If necessary, faces and edges of special type (planes, segments, cylinders, arcs of circles etc.) are automatically replaced with spline surfaces and curves.
Commands of deformation can be applied to both solid and sheet bodies (surfaces).
In the process of specifying all parameters of deformation operations, the future result of applying the current operation is dynamically displayed in the 3D window. To speed up the work, this dynamic view can be turned off.
