Dimension Labels¶

Dimension Labels applies the name of a Room to an individual dimension segment.

You select a dimension chain, identify the segment you want to label, then select a Room Tag. Flow reads the Name of the associated Room and places it below the selected dimension segment.

Ribbon: Flow → Annotation → Dimension Labels

When to Use Dimension Labels¶

Use Dimension Labels when dimension strings would benefit from additional room information.

This is particularly useful for continuous dimensions where individual segments relate to different rooms or spaces and the Room Name provides useful context alongside the dimension value.

Labels created through Dimension Labels are also designed to work with Join Dimensions.

Before You Start¶

Open a:

• Floor Plan, or
• Reflected Ceiling Plan

containing:

• a continuous dimension chain; and
• the Room Tag for the room name you want to apply.

Applying a Room Name¶

1. Select the Dimension¶

Start Dimension Labels.

Flow prompts:

Select a dimension. Press Esc to finish.

Select the continuous dimension containing the segment you want to label.

If you select something other than a dimension, Flow displays a message and allows you to try again.

2. Choose the Dimension Segment¶

Flow prompts:

Click the dimension segment to label.

Click close to the dimension segment that you want to label.

Flow identifies the dimension segment nearest to the point you click.

3. Select the Room Tag¶

Flow then prompts:

Select a Room Tag.

Select the Room Tag containing the Room Name you want to apply.

Flow identifies the Room associated with the selected tag and reads its Name.

If you select something other than a Room Tag, Flow displays a message and returns to the workflow.

If the selected Room Tag cannot be associated with a valid Room, no label is applied.

4. Flow Applies the Room Name¶

Flow writes the Room Name below the selected dimension segment.

After applying the label, Flow is immediately ready for another dimension.

Repeat the process for additional dimension segments as required.

Expected Result¶

The selected Room's Name appears below the chosen dimension segment.

The dimension value itself is unchanged.

The Room Tag is only used to identify the Room and obtain its Name; the Room Tag itself is not modified.

Choosing the Correct Segment¶

Dimension Labels works with individual segments within a continuous dimension chain.

After selecting the dimension, you identify the required segment by clicking near it.

Flow compares the clicked position with the available dimension segments and uses the nearest segment.

For dimension strings containing several short segments, zoom in if necessary before choosing the segment.

Existing Below Text¶

Dimension Labels writes the Room Name to the dimension segment's Below text.

If the selected segment already contains Below text, the existing text is replaced by the Room Name.

Room Information¶

The text applied to the dimension comes from the Name of the Room associated with the selected Room Tag.

Flow resolves the Room from the selected tag and then reads its Name.

If Flow cannot find a valid Room associated with the selected Room Tag, it displays a message and leaves the dimension unchanged.

Working with Join Dimensions¶

Room Names applied by Dimension Labels are stored as Below text on the dimension segments.

Join Dimensions preserves supported Below labels when compatible dimensions are recreated as a continuous dimension string.

This allows Room Names added through Dimension Labels to remain associated with the resulting dimension segments where they can be matched during the join.

If a Label Cannot Be Applied¶

Dimension Labels may display a message if:

• there is no active Revit document
• the active view is not a Floor Plan or Reflected Ceiling Plan
• the selected element is not a dimension
• the selected element is not a Room Tag
• the selected Room Tag cannot be associated with a valid Room
• the dimension is no longer valid
• Revit cannot apply the Room Name to the dimension

If an invalid dimension or Room Tag is selected, correct the selection and continue the workflow.

A failed label operation does not end the entire Dimension Labels session.

Repeating and Finishing¶

After successfully applying a Room Name, Flow returns to dimension selection.

You can continue labelling additional dimension segments without restarting the tool.

The sequence for each label is:

Select Dimension → Choose Segment → Select Room Tag

Press Esc during the interactive workflow when you have finished.

Dimension Labels exits cleanly and returns you to the Annotation window when launched from there.
