Have You Ever Wanted to Add a Tolerance to a Revit Dimension?

Hi folks IX here.  One of the Senior Application Specialist here at Ideate, Inc.

Have you ever wanted to add a Tolerance (±) to a dimension in Revit?  Well you can and here are a couple workflows for you…

Workflow 1 using Microsoft Character Map:

I’m using Windows 7 and found the character map program in the flowing location

• “Start > All Programs >> Accessories >>> System Tools >>>> Character Map

Once in the Character Map program I took the following step to copy the character

1. Select the Font: drop-down and select the font that you are using in your Revit project for your dimensions
2. Locate the Plus or Minus Symbol (±).  Double-click on the character to add it to the characters to copy section
3. Select the Copy button

Your tolerance symbol has now been added to the windows clipboard for pasting. 

Back in Revit follow these easy steps to add your copied tolerance symbol to a Revit dimension

1. Double-click on the dimension that you wish to add the Plus or Minus (±) symbol to
2. Select into the Suffix: field and right-click to get the menu
3. Select Paste from the menu
4. Add additional content to the field to finish your tolerance
5. Select the OK button to finish add the tolerance to the dimension

Workflow 2 using the Keystroke equivalent:

If you know the keystroke equivalent you can type it in into the Suffix: field.  In my example above for the Arial font you can insert the Plus or Minus (±) symbol by holding down the Alt key and typing the number 0177.

I hope that you enjoyed this Dimensioning Tolerance workflow tips and tricks.
