Adding or Removing an Inch Mark (") to Pipe Diameters

From a Customer:

Q: Is there a setting that allows you to put the inch mark (“) after pipe sizes? Some of our drawings have the inch mark and then newer drawings leave the mark off?

A: Yes. When you start a new drawing, there is a place there for adding a suffix. If you put in an inch mark, it will show up when you size pipe. If you want to change it after you have already started a drawing, pick the HydraTools pulldown then pick Options and then pick Access Drawing Unit Setup. The next time you elevate the drawing and bring it back down, the inch marks will appear/disappear as you set them.
