Scale Body in NX

You can scale solid bodies or sheet bodies by using the “Scale Body” command in NX Modeling.

Home Ribbon Bar => Base Group => More Drop down arrow => Offset Group => Scale Body

There are 3 scaling methods:

• Uniform:
• Axisymmetric
• Non-Uniform

Uniform Scaling

You can scale by using the same scaling factor in all x,y, and z directions.

1. Start the “Scale Body” command.
2. Select “Uniform” at the top of the dialog box.
3. Select Body to scale.
   “Select Body” in the “Body To Scale” group is highlighted automatically.
4. Click on the “Specify Point” bar in the “Scale Point” group in the dialog box. It will be highlighted.
5. Select a scaling center point in the graphics window.
6. Type the scaling factor into the “Uniform” box.
7. The scaled body preview will be seen in the figure.
8. Click “Ok” to scale the body and exit the command.

Axisymmetric Scaling

You can scale a body around an axis and along the same axis by using the Axisymmetric scaling method.

1. Start the “Scale Body” command.
2. Select the “Axisymmetric” method at the top of the dialog box.
3. Select Body to scale.
   “Select Body” in the “Body To Scale” group is highlighted automatically.
4. Click on the Specify Vector bar and select the Scaling axis in the graphics window.
5. Click on the “Specify Point” bar and select a scaling center in the graphics window.
6. Define the scaling values of the “Along Axis” and “Other Directions.
7. The scaled body preview will be seen in the figure.
8. Click “Ok” to scale the body and exit the command.

Non-Uniform Scaling

You can scale a selected body by using different scale values on x,y,z axis by using the Non-Uniform scaling method. Mostly used for volume changes in different directions after the molding or casting process. 

1. Start the “Scale Body” command.
2. Select the “Non-Uniform” method.
3. Select Body to scale.
4. Click on the “Specify CSYS” bar and select the scaling center in the graphics window.
5. Define “Scale Factors” in x,y, and z directions.
6. The scaled body preview will be seen in the figure.
7. Click “Ok” to scale the body and exit the command.
