Revit MEP - Silly Revit - We Don't use those Pipe or Duct Sizes

If you don't take the time to fine tune your project templates then you'll find Revit will offer you all kinds of pipe and duct sizes. These are available in the drop down lists during placement and then later if you run Duct/Pipe Sizing.

If you don't take the time to fine tune your template you'll find Revit gives you a duct size of 11" after completing its Duct Sizing, regardless of the fact you only choose from even sizes. It's easy to blame silly Revit...but it's our fault. The Duct and Pipe Sizes are controlled via Mechanical Settings, the duct sizes for Rectangular are shown below.

We need to either delete sizes we never want or just un-check them in either column or both, Set it and forget it.

Oh, the same is true of conduit and cable tray.

Specify Worksets and Save

We can preset the preference to use the Specify option when we open a project that has enabled Worksets. This option appears when we click the small arrow next to Open in the Open Dialog, which only works when we select a file with Worksets enabled.

This preference is controlled by a parameter called Open Workset default. It is only available to us within the Save As dialog, via the Options... button.

There is a subtle difference between enabling worksets in a file that has not been saved yet and one that has. If we enable worksets in a project that has already been saved, at least once before, we won't get a chance to change the setting if we just click Save. However if we use Save As we get the dialog that offers us the Options... button. The setting Open Workset default is not enabled unless the file is already using worksets.

This means it probably easiest to ensure that Specify is selected if we start a project and enable worksets before saving the file the first time. That might be easier said than done. If the file is already in progress and we need to enable Worksets we just need to use Save As instead, reusing the original file name if necessary.
