Extension

To produce an Extension of an Edge or a Face select in the Main Menu Operations - > Transformation - > Extension. The type of extension is defined using the radio buttons.

Firstly it is possible to resize an Edge by modifying its first and last parameters

Edge Extension

TUI Command: geompy.ExtendEdge(theEdge, theMin, theMax), where theEdge the input edge to be resized, theMin the minimal parameter value, theMax the maximal parameter value.
Arguments: Name + Object (Edge) + 2 values (Min and Max Parameters).

Example:

Original edge (white) and extended edge

Note

The input Edge parameters range is [0, 1]. If theMin parameter is negative, the input Edge is extended, otherwise it is shrinked by theMin parameter. If theMax is greater than 1, the Edge is extended, otherwise it is shrinked by theMax parameter.

Secondly it is possible to resize a Face by modifying its minimal and maximal U- and V-Parameters.

Face Extension

TUI Command: geompy.ExtendFace(theFace, theUMin, theUMax, theVMin, theVMax), where theFace the input face to be resized, theUMin the minimal U-Parameter value, theUMax the maximal U-Parameter value, theVMin the minimal V-Parameter value, theVMax the maximal V-Parameter value.
Arguments: Name + Object (Face) + 4 values (Min and Max U- and V-Parameters).

Example:

The original face (gray) and a result face shrinked along U-Direction and extended along V-Direction

Note

The input Face U- and V-Parameters range is [0, 1]. If theUMin parameter is negative, the input Face is extended, otherwise it is shrinked along U-Direction by theUMin parameter. If theUMax is greater than 1, the Face is extended, otherwise it is shrinked along U-Direction by theUMax parameter. The same applies to theVMin, theVMax and V-Direction of the input Face.

Our TUI Scripts provide you with useful examples of the use of Extension Operations.
