People utilize the coordinate systems in Siemens NX® CAD, but also they are much more important in UG CAM. To obtain a very professional CAD design in Siemens NX®, you need to understand the general working principle of coordinate systems in Siemens NX®. In this text, we will show you how to create coordinate systems in Siemens NX by using the Datum CSYS command. You could create special coordinate systems by following the steps below. You will see that creating coordinate systems in Siemens NX is very simple.

## How to Create a Coordinate System with Datum CSYS in Siemens NX®?

Firstly, to create a coordinate system in Siemens NX®, you need to click on the Datum CSYS command as shown by the red arrow above.

As you can see there are a bunch of methods to create a coordinate system in Siemens NX®, and you could place your new coordinate system dynamically that you could do your placement with arrows on screen as shown by red arrows, also you could do angular placement by using the handles as shown by green arrows. You could also input X, Y, and Z values and angular values to place your new coordinate system in Siemens NX®.

### Coordinate System Generating Methods in Siemens NX

**Inferred:** It is the most general method to create a coordinate system in Siemens NX®.

**Origin, X-Point, Y-Point: **You could input the X and Y places of your new coordinate system in Siemens NX®.

**X-Axis, Y-Axis, and Origin:** You could select the X and Y orientations of the new coordinate system by selecting lines or edges for them individually. And you select the center of your new coordinate system in Siemens NX®.

**Z-Axis, X-Axis, and Origin: **You could select the Z and X orientations of the new coordinate system by selecting lines or edges for them individually. And you select the center of your new coordinate system in Siemens NX®.

**Z-Axis, Y-Axis, and Origin:** You could select the Z and Y orientations of the new coordinate system by selecting lines or edges for them individually. And you select the center of your new coordinate system in Siemens NX®.

**Plane, X-Axis, Point:** You could define your new coordinate system’s place by selecting a plane, the orientation of X-Axis by selecting an edge or line, and a point to place your coordinate system in Siemens NX®.

**The plane, Y-Axis, Point:** You could define your new coordinate system’s place by selecting a plane, the orientation of Y-Axis by selecting an edge or line and a point to place your coordinate system in Siemens NX®.

**Three Planes: **You could select three planes in the drawing scheme in Siemens NX® to create your coordinate system.

**Absolute CSYS:** You can create a coordinate system in absolute point.

### Selecting a Reference Point for Coordinate System

Select a reference in Datum CSYS

Also, you select the reference point of your new coordinate system as in the green box in Siemens NX®. The placement of the new coordinate system will be done according to the selected reference.

**WCS:** Select the world coordinate system as a reference to create your new coordinate system in Siemens NX®.

**Absolute-Displayed Part:** You could select an absolute point of the part as a reference for your new coordinate system in Siemens NX®.

**Selected CSYS: **You could do the placement of your new coordinate system in Siemens NX® by selecting another coordinate system as a reference.

After that, you select the reference point of your new coordinate system as in the green box in Siemens NX®. The placement of the new coordinate system will be done according to the reference that you select.

**WCS:** Select the world coordinate system as a reference to create your new coordinate system in Siemens NX®.

**Absolute-Displayed Part:** You could select an absolute point of the part as a reference for your new coordinate system in Siemens NX®.

**Selected CSYS: **You could do the placement of your new coordinate system in Siemens NX® by selecting another coordinate system as a reference.

### Creating a New Coordinate System

Also, you could click on the Point Dialog as shown by the green box to place your coordinate system by entering X, Y, and Z values according to your selected reference.

Finally, after entering your X, Y, and Z values, click OK to complete the placement of your new coordinate system.

If you complete your placement adjustments of your new coordinate system, you click OK or Apply as shown by the green box. Also, you could adjust your coordinate system’s dimensions by entering a scale factor as shown by the green arrow.

So, we created a new coordinate system in Siemens NX® by using Datum CSYS as shown by the green arrow.
