Hey architects and designers! Today, I'm going to show you how to add dimensions in a 3D view in Revit. It's a super useful skill for accurately portraying your design in 3D. Here's how to do it:

Step 1: Open your 3D view in Revit. Navigate to the 'Annotate' tab on the ribbon at the top of the screen.

Step 2: Click on the 'Aligned' or 'Linear' dimension tool, depending on the type of dimension you want to add.

Step 3: Hover your cursor over the part of the 3D model where you want to add a dimension. Click to place the dimension line, and then move your cursor to position the dimension text.

Step 4: Repeat the process for each dimension you want to add in the 3D view.

Voila! You've just added dimensions to your 3D view in Revit. It's that simple! Now you can accurately showcase the measurements and proportions of your design in a 3D space. Give it a try and elevate the quality of your architectural presentations. Happy designing!
