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.

Interface Inequity - Modify Size

Revit MEP features Duct, Pipe, Conduit and Cable Tray all have a dialog that permits us to edit their information, chief among them is their sizes. Unfortunately the younger brothers, Conduit and Cable Trays, have a extra button, the Modify button that lets us easily change a setting for a size. The older brothers Duct and Pipe don't, pity! It's just like parents to let our younger siblings stay up later and easily modify their size!

In the must be nice category, the Cable Tray size portion of the dialog.

In the wishful thinking category, the Duct sizes.

Also in the wishful thinking category, the Pipe Sizes.

I wish it was as easy to add this sort of functionality into Revit as it was to copy and paste the modify button into these images!! I vote for component size equity!! Let us modify them, let us modify them!
