How to Divide a Line into Equal Parts in Revit?

To divide a line into equal parts in Revit, you typically split the line into segments and then use dimension constraints to make those segments equal.

Here's a step-by-step guide incorporating the standard method used in Revit:

Steps to Divide a Line Equally

Dividing a line or element edge into equally sized segments is a common task in Revit, often used for layout, placement, or detailing.

1. Draw or Select the Line: Start by having the line or edge of an element that you want to divide. You can draw a new detail line, model line, or select an edge of an existing wall, beam, or other element.
2. Split the Line: Use the Split Element tool (found on the Modify tab). According to the reference, this tool is accessed via the "Split icon" on the Toolbar. Click on the line at the points where you want to create divisions. You will need to click n-1 times to divide the line into n segments (e.g., click 3 times to get 4 segments). Don't worry about the segments being perfectly equal at this stage; the reference notes they "do not need to be equally spaced at this point."
3. Apply Dimensions: Activate the Dimension tool. As per the reference, this is found on the "Basics or Drafting tab of the Design bar" (in older versions) or typically on the Annotate tab in newer versions of Revit, under the Dimension panel (e.g., Aligned Dimension).
4. Create an Equal Dimension String: Click on the starting point of the line, then click on each split point you created, and finally click on the end point of the line. Place the dimension string by clicking in an empty area away from the line.
5. Engage the "EQ" Constraint: Once the dimension string is placed, you will see the measurement values for each segment. Near the dimension text, you will also see a small "EQ" symbol (it might initially show a standard dimension value like "1'-6""). Click on this "EQ" symbol. This action toggles the constraint, forcing all the dimensioned segments between the clicked points to become equal in length. The dimension text will change to "EQ" to indicate the constraint is active.

By following these steps, the line will automatically adjust, and the split segments will become equal in length. You can then use these equally spaced points for placing elements or further modifications.

Summary Table

Step	Tool Used	Location (Common)	Action	Outcome
1. Prepare Line	Draw/Select	N/A	Create or select the line.	Line exists for modification.
2. Split Line	Split Element	Modify tab (Toolbar/Ribbon)	Click on line to create split points.	Line is broken into multiple segments.
3. Dimension Segments	Dimension (e.g., Aligned)	Annotate tab (Dimension panel)	Click start, split points, and end of the line.	Dimension string shows segment lengths.
4. Make Equal	EQ Constraint	Near Dimension String	Click the "EQ" symbol on the dimension.	Segments become equally sized.

This method is standard for ensuring precise, equal divisions based on geometrical constraints in Revit.
