Additional Features of Face Taper

Taper of Face Relative to Multiple Fixed Faces/Edges

The operation allows tapering the selected face relative to multiple fixed faces or edges. As a result of such operation, the tapered face will be split into two parts. The edges of the resulting faces will have the specified taper angle.

Tapering All Adjacent Faces

The mode of tapering all faces adjacent to the fixed one is provided for quick taper creation. In this case, all you need is just to select the fixed face. The command will automatically determine all adjacent faces for tapering.

Combined Processing of Adjacent Faces

The mode of combined processing of adjacent faces allows the user to create a simultaneous taper for a pair of adjacent faces, when one of the tapered faces serves as a fixed face for another. In a standard mode, an attempt to create such a taper will lead to an error.

On the figure below an example is shown in which it is desired to simultaneously taper two faces: “Face 1” and “Face 2”. For the face “Face 1”, the edge “Edge 1” is selected as a fixed edge. For the “Face 2” a fixed line has to be defined by the face “Face 1” or the edge “Edge 2”. But both “Face 1” and “Edge 2” will be modified upon taper creation. In this situation, the mode of combined processing of faces can help. By turning it on and indicating “Face 1” as a fixed object for the face “Face 2”, the user can obtain a correct taper of two faces at the same time.

         

Splitting Faces

This parameter is used in cases when it is necessary to create a taper of the curvilinear face. The command splits the face into patches defining the position for which it is possible to create a taper surface. The tapered patches will pass tangentially to the remaining curvilinear part of the face at a specified angle to the taper direction.

For creating the taper with face splitting, the user has to specify a face which is to be split as a fixed face (a tapered face in this case is not specified) and activate the flag Split Faces.

Note that the functionality of splitting faces remains in the command for compatibility with earlier versions of T-FLEX CAD. The currently available Imprint Elements command provides various ways of dividing a curvilinear face into pieces for further tapering.

Taper by offset

The method of specifying the taper “by offset” allows the user to determine the magnitude of a taper not by an angle but by an offset of the tapered face with respect to the initial position.

The algorithm of creating the taper “by offset” method is as follows:

•A fixed face or edge is mapped along the taper direction on the plane selected for defining the face offset.

•A specified-distance offset from the mapped face or edge is constructed. In this case, the taper parameter is the offset distance.

•The resulting surface will be passing through the offset off the fixed edge’s mapped image.

3D Fragment Supplement Mode

The option automatically becomes available in the command's automenu when selecting elements on a fragment in an assembly.
