Saving Your Work
Save Your Drawings; Do Not Close without Saving​
When working with Design Master HVAC, it is important to save your drawings after making any changes. Do not close your drawings without saving.
Design Master Database File​
Working with drawings using Design Master HVAC is a little different than working with just a CAD drawing. Any changes you make using the Design Master HVAC commands change both the drawing and the database. The changes to the database are made immediately. The changes to the drawing are made when you save the drawing.
If you close a drawing without saving, you can have changes in the database that are not on the drawing. That's bad.
Recovering When a Drawing is Closed with Saving​
If a drawing is closed without saving (for example, your CAD program crashes), run the Coordinate Drawings and Database command. The command will look at the drawing and the database and make them match.
Anything that is added to the drawing will be marked with a line. You can erase the lines manually or use the Erase Coordination Lines command to remove them all. The devices that are added should be modified using standard commands. Erase them if you don't need them, move them if they are not in the right spot, or leave them be if they are correct.
