This tip demonstrates how to use MagiCAD to help find open-ended pipes

Rainer Wiljanen shares a tip for rectifying pipe systems using MagiCAD for AutoCAD.

“Here’s how to locate open ends in heating and cooling systems quickly and efficiently using MagiCAD for AutoCAD. When dimensioning heating or cooling systems, the user is sometimes notified with the error message, ‘Different flows on the root pipes.’ This message is most commonly caused by devices within the system (e.g., radiators) that have not been connected properly to supply or return pipes. These open ends cause a discrepancy between supply and return flow rates, which MagiCAD detects and then notifies the user accordingly.

“Open ends are easy to locate using Part Property Line. To access this function, select MAGIhpvView > Part Property Line from the classic MagiCAD main menu, or MagiCAD HP&V > Annotation > Text > Part Property Line from the new ribbon interface.

“Select heating, cooling, and special systems as the system group, and select open ends as the property to be highlighted. An alternative method is examining all pipes with flow rate discrepancies by selecting flow (l/h) as the property instead. This method finds all flow rate discrepancies within the system and is not restricted to those caused by open ends.”

“Be sure to define a large text height to make textual markers easy to locate in the drawings. Click OK.

“Open ends are now highlighted on each drawing by large textual markers, enabling quick and efficient revision of each missing pipe connection.”

Notes from Cadalyst Tip Reviewer Brian Benton: MagiCAD is third-party software that runs in AutoCAD (there is also Revit Suite) and provides tools and data for 3D content related to HVAC work, piping, electrical, and more. This tip demonstrates how to use MagiCAD to help find open-ended pipes. I didn’t have access to MagiCAD at the time of writing this, so I couldn’t fully test it out.
