This command can be used to set the Surface reference and set the Alignment reference for a Pressure Appurtenance part reference.

Pressure Appurtenance parts are a very important component of Autodesk® Civil 3D®. When working with a large number of Pressure Appurtenances, issues can arise if references are not properly defined.

When a Pressure Network is created without defining its Alignment or Surface references, each Pressure Appurtenance will also lack an Alignment reference and a Surface reference. Without these references, information related to the Pressure Appurtenance cannot be displayed correctly.

Therefore, it is necessary to define the Alignment reference or Surface reference for Pressure Appurtenance parts in order to display their information accurately.

Additionally, the Alignment reference or Surface reference for each Pressure Appurtenance can be changed later if required.

To address this efficiently:

• We want to set the Surface reference for multiple Pressure Appurtenance parts using a single command, without having to repeat the command for each part.
• Similarly, we want to set the Alignment reference for multiple Pressure Appurtenance parts using another command.

This functionality is achieved through dedicated commands that allow batch assignment of Surface and Alignment references.
