AutoCAD Architecture Custom Room Area Tags

In AutoCAD Architecture, the Room Tag Style that comes with the program will read out the Room name and number for a Space. Often, you may also want to print out the area of the Space (in sq ft).

Here is a step by step guide on how to create your own Room Tag that includes the area. There are several more properties you can potentially add to the Tag. This guide will help you get started in tag customization, by creating your first custom Room Tag.


First, the automatic property called “BaseArea” needs to be added to a Property Set Definition. I’m adding it to the “SpaceObjects” Property Set Definition.

1. In the Manage Ribbon, open the Style Manager. Under Documentation Objects find Property Set Definitions. Select “SpaceObjects”.

2. In the Definition tab click on the “Add Automatic Property Definition” Button.

3. In the new window, check mark “Base Area”.

Here’s a picture of how to add the area automatic property. Click on the image to see a larger version.


Next, we create the objects that will become the block used for the Tag.

4. In the model space, set the annotation scale to 1:1.

This step is necessary because Tags in AutoCAD Arch are annotative (auto-scaling). Changing the annotation scale in the status bar to 1:1 makes sure the Tag’s text will be the correct size.

5. Place a Room Tag. Explode the Room Tag until it reads the Attribute Definition Tag names.

6. Copy the “SPACEOBJECTS:NUMBER” Attribute and edit to create an Attribute with Tag “SPACEOBJECTS:BASEAREA”.

7. Add text if you want the units to be displayed.

Here is a picture of what my objects look like at this point.


Now we create the Tag using the objects previously drawn.

8. In the Annotate Ribbon, expand the Scheduling panel. Select “Create Tab”.

9. On screen, select the objects you would like included in the Tag block (Attributes, Lines, Text).

10. In the Define Schedule Tag Dialog Box, type in a new name for the Tag. I’m using Room_Area_Tag.

11. Double check that the labels are assigned the correct properties and click the OK button.


12. Specify an insertion point to place the new Room Tag.

Finally we get to place the custom Tag.

13. Use the Room Tag tool to place Tags over the Spaces (rooms).

14. Select the Tag and use the properties window to change the Tag Definition to “Room_Area_Tag”.

  1. Thanks for sharing. I tried to use this method for room dimensions but it comes in inches instead of feet. How to do this?

  2. Hi Evelyn,
    This was very helpful. I am struggling with spaces as it relates to custom door numbers, custom window symbols, finishes and then exporting into a schedule.
    Do you have other posts that deal with such things?
    Thank you,

  3. This post is helpful, but I have more questions. How do you add a ROOM TAG without associating a space zone to it? In Line 7, how did you add the ‘SQ. FT’? I also have the room dimensions in inches instead of feet.

    1. Michele,

      AutoCAD Architecture requires a space to assign the tag to. However, you can manually insert the block after you define the block. Using CLASSININSERT for the image below.

      The SQ. FT. is just AutoCAD text, not an attribute. I just put after the attribute.

    1. Hitan,

      This also applied to Michele’s question. Using inches instead of feet and change the precision to 2 instead of three. These are all defined in “Property Data Formats” in the style manager. It’s right above “Property Set Definitions”. For example…

      I had to delete the room tag and recreate it to get the units to update.

      It’s great to see the inquisitiveness and involvement from the community! 🙂

  4. Jay,

    If you look at the property set definition there is a width and length property. Use those in separate attributes (same method) but be careful about the units. I think by default they will be in inches.

  5. I’ve been attempting to use this process to create a room tag and it does not seem to be working. Once I’m done the tag is either way too big or way too small. I am using US Imperial measurements and started with an annotation scale of 1′ = 1′ and that didn’t work for my sizing issue. I kept trying with all different annotation scales and nothing worked. Now, when I use anything larger than 3/8″ = 1′ I can’t see the spaces or tags, so I tried adding the spaces and tags while in 1′ = 1′ then changing to a different annotation so I could actually edit the tag but I kept having the same issue. Any solution?

    1. Matthew,

      If you started with a scale of 1:1 when defining the tag, you need to scale the block 12 times because of the difference in feet to inches. This should solve the sizing concerns.
