Description

Deforms a region, one or more connected faces of a 3D solid or a surface by moving a point lying on one of them in arbitrary 3D direction. The selected faces are deformed as smooth as possible. The initial continuity between deformed faces (G1 – tangent faces, or G2 – curvature continuity) is kept when deformed.

Select a region or a face or some connected faces of a 3D solid or surface, then specify the deformation point and the deformation value to deform the entity.

Options

change Parameters: Choose a method to change parameters.

Alpha

Specifies the resistance to stretching. It is a second order tensor which can be described with three numbers. Each value must be either 0 or a positive number:

alpha U: U-direction resistance,
alpha V: V-direction resistance,
alpha theta: the angle between U and V principal directions of the surface and the material property directions.

Beta: Specifies the resistance to bending. Similarly to Alpha, Beta is defined as a triple: beta U, beta V, beta theta. Each value must be either 0 or a positive number.

Gamma: Specifies the resistance to the rate of change in bending. The value must be either 0 or a positive number.

Delta: Specifies the resistance to deviations from the default shape. The value must be either 0 or a positive number.

set Target Point: The entities are deformed towards the specified point.

set Direction: The selected entities are deformed dynamically in the specified direction.

change Base point: Select a new deformation point.
