This section covers the various types of annoations that are often included in sets of drawings. 

AN.1. To see a list of the tags that are already loaded into your project, open the Annotation Symbols list under Families in the Project Browser.

AN.2. One type of tag is a room tag. In Revit a room can be assigned a room tag. By defining rooms, you can also populate schedules. For rooms that have four enclosing walls, use the Room tag tool.

AN.3. Once you have selected the Room tool, click within the room. In the image below a room with four walls has been selected. The rooms will be numbered in order of placement, but can be changed later. Generally, it is good practice to begin the numbering at the building's entrance and proceed in a clockwise or counter-clockwise rotation around the plan. If, for example, someone is trying to find a specific room number it will be easier to because it is in sequence.

AN.4. Changing the scale will affect the scale of the annotations. The plan below will be printed at 1/4"=1'-0". That scale is appropriate for residential architecture. Commercial or institutional architecture often uses a scale of 1/8"=1'-0". 

AN.5. If a room does not have a clear division, you can add a room separator line. 

AN.6. A room separator line has been added and the space has been designated as a room.


AN.7. Continue to designate rooms for all levels of your building. Then edit the numbers for the rooms. Start with the lowest level and name the first room at the entrance (lobby, foyer, etc.) room number 101. Move in a clockwise or counterclockwise direction around the plan numbering the rooms in sequence. There should be no gaps in the sequence like this: 101, 102, 103, etc. and not 101, 103, 107, etc.. This method makes it easy for someone to find a particular room number on the plan. If you have named the level Basement make the first number 001. On your second level start with 201.

AN.8. Using the Tag All tool you can include the tags for all instances of a category. 

AN.9. Select a Category, and click on Apply.

AN.10. In the image below, the Window Tags are now visible. The numbers can be changed later.

AN.11. Repeat the steps above for the Door Tags. If the tags are on top of other content, you can click on them and use the Move tool to shift them. Go around and number the doors. The number method should follow the same pattern as the room numbers. If a room is 108, the doors should be associated with that number. The entrance to the room might be 108a. A closet door in that room might be 108b. Again this makes it easy for someone to find a particular door.

AN.12. Eliminate grid lines that were not used to locate walls, floors and roofs. Renumber or re-letter as necessary. If the grid is part of an array, you will need to click on a grid line and select Edit Group to change the text. In the image below 5 & 6 will be eliminated because no walls or major elements are located along them. Column line 7 will be renumbered to 3. Feel in mind that Revit won't allow you to use a number that is already in use. Assign numbers to the column lines that run north-south. Assign letters to the column lines that run east-west.

AN.13. Dimensioning can be very complicated and time consuming if you have have not been methodical in the placement of objects in your project. If you have been methodical, the dimensioning process is very straightforward. Keep in mind that the goal with dimensioning is to clearly describe where building elements are placed.

The video below describes some procedures for working with dimensions. However, the method shows dimensioning from the face of walls. Your project uses column grids instead. You will be dimensioning to your column lines.


Dimension the exterior walls first. Similar to the example in the video, show one overall horizontal dimension between the outermost column lines and one overall vertical dimension. In the next string of dimensions locate any changes in the profile of your structure. These dimensions should snap to the column lines. In the third string locate window and door centerlines relative to column lines.

If you have a typical guest room, show the dimensions at just one room. You don't need to repeat the dimensions for all of them. 

If there are interior walls that have not been located include dimensions for them. One isolated dimension would not be very informative so make continuous strings of dimensions that tie to column lines. 

Note: You can change the rounding setting so dimensions are not too small. The tolerance varies depending on the project, but generally dimensions should never be smaller than 1/8". A 1/4" tolerance is common. Keep in mind that a dimension string still needs to add up to the same dimension so use the rounding feature with caution. You can suppress the leading zeros in a dimension as shown below. If you suppress the feet, then you can more easily fit a small dimension in a string. Three inches would appear as 3" instead of 0'-3".


AN.13. Add material notes to the exterior elevations using the Material Tag tool. A leader is a line and arrow head that connects text to a reference point. The leader can be completely horizontal or bent like the image below. There must be a horizontal portion of the leader (next to the text. The 1, 2 & 3 identify the selection points. You can edit the text as necessary to identify the material you intend to use. 

The orange lines shown above and below are alignment lines. Note that it is not necessary to draw them. They are shown to illustrate alignments. Always line up your text with left justification. If the text is on the left side of the leader arrow, it is also acceptable to right align your notes.

If a question mark appears, a material has not been assigned to the category. You can also change the text that appears, as with the "physical material" text shown below, by going through these steps.

To assign a material to a component, click on the Object Styles on the Manage ribbon. Find the component in the list and click on the cell under the Materials columns.

Choose a material.  Click on the Identity Tab. Change the Description text. That text will appear as the note.  

Apply the changes. The note annotations should automatically update. 

AN.14. Change the leader so that it has an arrow head.

AN.15. Include material notes on all elevations.
