Scaling

Use this command to scale objects.

Scaling

Step 1

For the prompt Specify objects, select objects to scale. You can select multiple objects. Press Enter key to finish the selection.

Step 2

For the prompt Specify the origin of the transform, locate the origin point of the scaling transform.

Pressing 1 key, 1D scaling mode is invoked. 1D scaling transforms objects only toward the designated direction. E.g.,when the designated direction is X axis, the scaling is applied only to the x coordinate, and is not applied to Y and Z coordinates.

Pressing 2 key, 2D scaling mode is invoked. 2D scaling transforms objects along the designated direciton D1 and along the 90 degree rotated direction of D1 around the normal of the CPlane. E.g., when the designated direction is X axis, the scaling is applied to the X and Y coordinates, and is not applied to Z coordinate.

Pressing 3 key, the normal scaling(3D) is invoked. This is the defalut scaling. 3D scaling does not have a direction.

Step 3

When 1D, 2D Scaling

While Specify scaling direction is prompted, located the end point of the scaling direction, whose starting point is Step2's scaling origin. The length between the scaling origin and the end point of this direction's end is the base length to measure the scaling factor.

When 3D scaling

While Specify the end point of the base line to measure scaling factor is pormpted, locate the end point. 3D scaling does not use the direction, only use the length.

Fugen sets the input as Tab mode. The next point(base line 2's end point) is urged to be on the straight(or the extend) from the scaling origin to this point.

Pressing K key, scaling factor input dialogue is shown. The factor is able to input using KB.

Step 4

For the prompt Specify the end point to measure scaling factor, locate the end point. Let the points specified in Step 2, 3, and 4 be O, A, and B, respectively, the scaling factor is defined as the ratio OB : OA. The scaling factor depends only on their lengths, not directions.

After this locating, this command scales the objects.
