We all know it’s impossible to have a Calculated Value in a Tag so how do i manage to still show the information?
Well we could simply use a Dumb Field all manually copy the value.
The problem though is that, if like in Room C, you made modifications to the model and now the Tag Value is not updated.
To Fix that we will use the Conditional Formula feature
Will start by adding another Calculated Value
Name: Switch
Type: Yes/No
Formula: abs(Total – Tag Value) < 1
Note: ABS returns a positive value. If your area is rounded down your resulting variance will be different than if it was rounded up. So the ABS function takes care of that (always making sure you get a positive number)
EX: 789.3 shows as 789. Then you type 789, so the variance is 789.3-789 = 0.3
If you have 789.7 it would show as 790, then you type 790 but the variance would be 789.7 - 790 = =-0.3
Now let’s add the Conditional Formula. Here we want to show the Switch cell Red if the value is no.
Every time that the value between Calculated Value and Tag Value is different we get a Red No in the Switch Parameter.
That way we can visually check the schedule before printing.

say your libraries:
Open a command prompt by pressing the Windows Key and R simultaneously.
+
Enter cmd and click Ok
Navigate to your library folder
Our example is C:\RevitLibraries\R2010\RAC\Autodesk\Imperial Library
From there type: dir /s /w >Content.txt (Content.txt being the name of the output file)
and press enter.
You now have a Content.txt in the library folder
Open it and you now have a list of the content.
When using software like Adobe Illustrator or Adobe Photoshop i prefer using EPS then PDF. The format is “cleaner” then a PDF and comes out as great outlines. But an EPS printer doesn’t come with Revit or the others software install. Here’s how to do it.
Install the EPS printer from Adobe’s site (You might have to contact IT for that part)http://www.adobe.com/support/downloads/product.jsp?product=44&platform=Windows
From Revit simply select the Generic PostScript Printer
One thing that i stress when creating a library and working on a project is to take a minute to think about how elements interact together. Here’s a file that i created to explain the interaction between the elements. That should help getting closer to an adequate level of detail faster.
Here’s a sample
If you want a copy of the file, just email us at blogger @ revitit.com
You want to delete several elements quickly, here’s a way.
Keep the Del key pressed and simply click on the elements you wish to delete.
Quick and Dirty but works like a charm
Sometimes you need to display both unit system (Imperial & Metric) say for example in a room schedule.
Create a schedule that display the project units (Imperial in this example). I renamed the Area header for Area Imperial.
Create a calculated value and name it Area Metric. Enter Area in the Formula field.
In the Formatting tab select Area Metric and click Field Format…
Uncheck Use Project Settings, change the Units for Square meters and set the other options as needed.
We now have a dynamic way of displaying both values.
Some of you might not remember that there is various options for a Railing sketch… especially when attached to a stair.
Take that Railing for example
By default the way it slope is set to By Host
But you can change that option to Flat or Sloped. Flat in that example will look like that
Stair sketch will be set as Auto-Detect but can also be set to Flat or Sloped.
Here’s what Flat will do
We all know about using the TAB key to select connected elements
But what if i want to only select the South Walls
I could use a window but then i would have to use the filter to remove the doors from my selection.
Here’s a quicker way to do it.
Select the first wall
Place your cursor over the last wall needed in the sequence
THEN press TAB 
The order will depend on the way the walls were built.
We all know that Revit’s ability to generate Tile fill pattern is limited to crossing lines.
Chris Baze wrote a nice Excel file to help you achieve a little bit more detail in a lot faster way then using Notepad.
Simply fill in the information for Height, Width & Grout Width
Then copy the bottom portion into a text file (make sure you save as a .pat)
Now import it into Revit
Then you use as needed
You can get the Excel file in the link below thanks to Chris.
