Delete Revit Backup Files - Everywhere!

If you know me, you know I am the opposite of a hoarder when it comes to electronic files. I love deleting things. It just brings me joy to delete data. So, Revit's need to create backups, just bugs me. It does not feel like good file maintenance to have all kinds of backups everywhere, and a bit dangerous when newbies open these files by mistake.

So once again, DOS to the rescue. Place this text in a batch file and save it in the root directory that you want to clean up.
del /s /F *.0*.rvt
del /s /F *.0*.rfa

del /s /F *.0*.rte
This will delete all the backups of projects, families, and templates in the root and every sub-folder that follows. Double click the BAT file and your work is done.  the /s tells DOS to delete files that meet the criteria in sub-folders, and the /F tells DOS to go ahead and delete locked files. 

To see what you just deleted and the word "pause" to the last line like this:
del /s /F *.0*.rvt
del /s /F *.0*.rfa

del /s /F *.0*.rte

If you want to know what you are deleting before you delete it. this this.
dir /s *.0*.rvt
dir /s *.0*.rfa

dir /s *.0*.rte


All of this works for me because a great IT department means I can restore old files at any time. If you don't have the same confidence, act accordingly.

Tags That show Imperial and Metric Units

I got question from long time friend last week asking if it were possible to tag a duct with imperial and metric units. He needed the tag to show  as
 12x12 (300x300)

On the surface it might seem impossible. The units for a Revit project are one or the other, but you can beat this by creating a special Tag family. For this tag start with the Generic Tag.rft template and categorize it as a Duct Tag. Add three labels in a row; SizeHeight, and Width. Use the Prefix and Suffix columns to add the open and closed parenthesis. Now select the Height parameter in the Edit Label dialog. Use the icon at the bottom with the image of the hand over the pound sign to change the format by un-checking "Use project settings" and then setting the units to Millimeters. Do the same for Width, and you have a mighty fine duct tag that will show imperial and metric units at the same time.

Look Familar... hmmmm

You probably know this already, but I didn't until I looked up at a recent visit to Autodesk's offices in San Francisco.

If I ever invent a software, when it is time to design the box. I am just going to take a picture of the ceiling. It turned out great Autodesk. Bravo!

Revit Shortcuts for Old People

I'm older than I used to be. A long time ago, I used AutoCAD and maintained a quick speed, thanks in large part to custom key-ins. Most of my AutoCAD key-ins were just a single letter, which Revit is not %100 thrilled with. Revit will play ball with a single letter key-in if you delete every other key-in that starts with that same letter. 

So, here are the key-ins I created for myself that maybe no one else will ever care about, and the classic AutoCAD commands they remind me of.

A    Align 
B    Split Element (Break)
C    Copy (Copy)
D    Duct
E    Delete (Erase)
F    Trim/Extend (Fillet)
G    Group
H    Filled Region (Boundary Hatch)
I     Link Revit (Insert)
KS   Keyboard Shortcuts
L     Detail Line (Line)
M    Mirror (Mirror)
O    Offset (Offset)
P     Pipe
Q     Synchronize (Quick Save)
RC   Revision Cloud
RP   Reference Plane
T     Trim/Extend (Trim)
X     Ungroup (Explode... yeah, I know)

Do yourself a favor though, type KS, and customize your own key-ins.

Valves Inherit Pipe Line Types

It is nice when you add a valve to a pipe in single line and it inherits the color of the pipe. It's not so great when it also inherits the line type of the pipe when that line type is hidden. You get something that looks like this.

You can override the graphics in view of each of the valves to force the line type to continuous, but you are probably better off just creating a filter.

This one looks for all the pipe accessories in a view, then applies a solid override to the lines.

Done and Done.

Get PLT files from Revit

It's a crazy world sometimes. Like when you create a wonderful Revit model and your client wants PLT files as the deliverable. Here is how to do it.

  1. In the Print dialog, check the box for Print to File. You need to select a printer that doesn't already print to file by the way.
  2. Click the Browse button to indicate where the file should be saved.

3. Change the Files of Type to Plot Files.

That was a lot easier than I thought.

Looking for AUGIWorld Revit MEP Authors

I am looking for Revit MEP authors who would like to contribute to AUGIWorld Magazine. I know I have readers that have something to share, so pitch me your ideas and let's see if you have what it takes to get your mug in the pages of AUGIWorld. 

Articles should cover a Revit MEP topic, be around 2000 words, and be something, well something you would like to read.

If you are up to the challenge, please email me at

Change the Number of Lines in Room Tags

This comes from Club Revit's Linked In page. A user asked how to change the number of lines in a room tag and Kerry Ward had an interesting take on things. She provided this trick...

"Name the room (single line text) then select the room (not the tag). Go to properties and under Identity Date / Name place your cursor in location where you want the text to split into 2nd line. Then hold down ctrl key and press enter, then apply. The room tag is then split into 2 lines."

I added quite a few breaks in the example image below to demonstrate how far you can take it. You can see that it comes with the side effect of reflecting in schedules. On the MEP side of things it may not matter at all. 

If you are curious, changes the room names in linked files will propagate into the space tags that call the room names.

IMAGINiT Answers from Joe Eichenseer

Tradition has it that the fine folks at IMAGINiT answer 3 questions of the CAD Shack before the conference is over. This year Joe Eichenseer does the honors. Always a pleasure, and always informative. Thanks Joe!
