Location: Transform>Scale Unidirectional Options
The Scale Unidirectional functions increase or decrease the size of selected entities by changing their data. These functions are used to change the size of geometry in one direction, while leaving the size unchanged in other directions; thus creating a stretching or squeezing effect with the geometry. The distance from the base plane to the moved position is a specified scale factor multiplied by the distance from the base plane to the original position. The base plane is the plane normal to the scaling direction; it contains the base position. When using these functions, it will be important to keep the following in mind:
Using the Function:
Select Scale Unidirectional>Move, Copy, or Join (see icons below) from the Transform>Scale submenu.
