User-Defined Coordinates for Component Orientation

You can add a SOLIDWORKS® user-defined coordinate system to a component that is not modeled with the SOLIDWORKS origin. You might obtain such components from a manufacturer website or from other CAD systems.

CircuitWorks™ assigns the user-defined coordinate system as the ECAD origin when you export the assembly into CircuitWorks.

If you insert components without a user-defined coordinate system into a CircuitWorks assembly, CircuitWorks assigns SOLIDWORKS origin as the ECAD origin.

To add your own coordinates to a component, see SOLIDWORKS Help: Coordinate Systems.

When you name the user-defined coordinate system CWX before inserting the component in the CircuitWorks Library, CircuitWorks assigns the user-defined coordinate system as the ECAD origin and correctly positions the components when you insert them into a circuit board assembly.

CircuitWorks interprets the positive Z-direction of a user-defined coordinate system as perpendicular to a circuit board assembly. The XY plane represents the board surface, and the X- and Y- directions control the angle at which the component is inserted into the assembly.
To assign a name other than CWX to the user-defined coordinate system representing the ECAD origin, click Tools > CircuitWorks > CircuitWorks Options , select SOLIDWORKS Export, and modify the Import and export components relative to this coordinate system option.

Example: LED Orientation With and Without Coordinates Defined

The coordinates of an externally manufactured LED set the Z-direction parallel to the base of the LED.

You add the LED to the CircuitWorks Library without defining a coordinate system named CWX. When you insert the LED components into the board assembly after building it in CircuitWorks, the LEDs are horizontal.

Before adding the component to the CircuitWorks Library, add a coordinate system named CWX to the LED component in SOLIDWORKS.

The LEDs are properly oriented when you insert them into the board assembly.
