# Configuration Settings
Total measure settings can be found in the Configurations window of Smart Dimensions:
There are settings for Horizontal, Vertical, and Diagonal **total** dimensions. You can switch any of them ON or OFF.
**Horizontal** and **Vertical Total Dimension** settings will give the overall dimension of all elements that have been selected to be **Included in Total Measure**.
Example. Only Walls have been selected to be included in the total measure:
Now, if Face-based details are also selected to be **Included in Total Measure**, then the total dimension will include them as well:
You can select a few other options as well.
**Dimension Side** - just select where the total dimension should be placed.
**Dimension Type -** select from the dimension styles available in the project.
**First Dimension Offset** - this value will be multiplied by the Dimension Line Snap Distance parameter and used to offset the first dimension line from the measured element.
**Text Note -** any text may be added here and it will be created near the total dimension line.
Also, there is an option for **Diagonal Dimension**. This will place the diagonal dimension for the assembly from the bottom left to the top right corner using the selected dimensioning style:
**Measure Elements from Linked Models** - this will allow your dimensions to snap elements from linked models. In the example below an MEP project has a linked Revit project with walls and openings (face-based void families). Smart Dimensions can measure those now:
