In NX modeling, you can trim a body or body set using a face or plane. The trimmed side of the body will be removed from the body.
For trimming bodies the “Trim Body” command is used.
- Home Ribbon Bar => Base Group => Combine => Drop-Down => Trim Body
- Menu => Insert => Trim => Trim Body
To Trim Bodies in NX Modeling
- Start the “Trim Body” command.
- The “Trim Body” command dialog box will open. The “Select Body” function is automatically active at the start.
- Select Bod/Bodies to trim
- Activate the “Select Face or Plane” function in the “Tool” group. To activate this function:
- Click on “Select Face or Plane” in the dialog box.
- one click on the middle mouse button
- The trimmed body preview will be seen in the graphics window.
- Click “Ok” to finish the command.

Note: You might see an alert as “The tool and target do not form a complete intersection or have a touch condition which will result in a region with zero wall thickness”
This problem occurs because
- the trimming face does not completely pass through the body.
- There is a tangent contact between the trimming body and the tool face as shown in the figure.
