Compare Body in NX CAM

NX CAM QuickTip | How to see changes on your workpiece in NX

Heinrich Flaum | 02/15/2023

In this NX CAM QuickTip, we will show you the new "Compare Body" feature that allows you to quickly view differences between parts. Quite often we have one or more revisions of our part. How can we now quickly and easily display the differences between two parts?

Siemens NX provides us with the "Compare Body" function for this purpose.

In our QuickTip, Heinrich Flaum shows you how this works.

Step by Step

Go to "Analysis" in the main menu and then click on "Compare Body" in the tab. In the window that opens, you must now define a sample body and a comparison body. If you then click on Compare, the two parts will be displayed below each other in the same window. The differences between the components are now highlighted in color. In our example we see many yellow markings on the lower part (yellow stands for changed areas of the part). In the upper window we also see two red marks (red stands for absent).

In the right window, NX has given you both versions of the part on top of each other. Using the slider in the menu window, you can make the overlay view in the right window paler or stronger. Thanks to the Compare Body function, you can easily handle different revisions of a part in Siemens NX and quickly view the differences.

Alternative (outdated): Model Comparison

If you use an older version of Siemens NX, you may know this function under its prior name "Model Comparison". We also did a tutorial on that older version.
