- UNIDIR allows you to move each position of the selected
- entities in a scaling direction normal to a base
- plane. It has the effect of stretching or squeezing the
- geometry. The base plane is a plane that passes through a
- selected base position. The base plane is either
- perpendicular to a selected vector or parallel to a plane
- as defined by a selected view or a 2-D entity. The
- distance each position is moved depends on the scale
- factor.
-
- Indicate the method of transformation by choosing from the
- following options:
-
- MOVE - to apply the transformation directly to the
- selected entities. All non-geometric data relating to
- the entities is preserved.
-
- COPY - to apply the transformation to copies of the
- selected entities. Copies are created on the active level
- and retain the attributes of the original geometry. All
- non-geometric data relating to the entities is preserved.
- You can create as many copies as you want in one
- operation. The transformation for a given copy is
- applied to the results of the previous copy.
-
- JOIN - to apply the transformation to copies of the
- selected entities and create lines from join positions on
- the original entities to corresponding positions on the
- copies. The new joining entities are lines that assume
- all the current default line attributes. Coincident
- positions generate only one joining entity.
-
- Joined copies are created on the active level; all
- non-geometric data relating to the entities is preserved;
- you can create as many copies as you want in one
- operation; the transformation for a given copy is applied
- to the results of the previous copy.
-
- If you are using COPY or JOIN, enter the desired number of
- copies and press <Enter>.
-
- Select the desired entities to scale, using a Selection
- Menu option.
-
- Indicate a base position, using a Position Menu option.
-
- Define the scaling direction by choosing from the
- following options:
-
- 2 PTS - to define the scaling direction by creating a
- vector, which is defined by choosing two points. The
- entity is scaled from a base plane that runs normal to
- the defined vector. Indicate the two positions, using
- the Position Menu.
-
- KEY-IN - to key-in the scaling direction vector. The
- entity is scaled from a base plane that runs normal to
- the defined vector and through the base position. The
- COORD: function in the Status Window indicates whether
- the coordinates are world or view. Key-in the x, y, and z
- values of the desired vector.
-
- VIEW - to define the scaling direction as being
- perpendicular to a view's display plane. The entity is
- scaled vertically from a plane that runs through the base
- position and parallel to the view's display plane. Key-in
- the desired view number.
-
- 2D ENT - to define the scaling direction as being
- perpendicular to a plane as defined by an arc, conic, or
- 2-D spline. The entity is scaled from a plane that runs
- through the base position and parallel to the plane
- defined by the arc, conic, or 2-D spline. Select the
- desired 2-D entity.
-
- Enter the desired scale factor.
-
- If using MOVE, you can choose from the following options:
-
- CONT - to continue transforming the selected entities.
-
- UNDO - to reverse the move and return the geometry (of the
- selected entities) to what it was before the move.
