How to calculate wire length in Revit

Calculating wire lengths in Revit projects is an important task that can help accurately estimate material requirements and optimize routing designs. Revit provides a variety of methods to calculate wire length. This article will introduce these methods and provide detailed steps. By reading this guide, you can master the techniques of calculating wire lengths in Revit, thereby improving project accuracy and efficiency.

1. The method used here is to use the wire tube command to draw a wire tube model based on the actual direction of the wire to replace the wire.

2. After drawing the wire tube, you will find that the number of wires in the wire tube is different. The calculated wire tubes cannot meet our requirements. You can add a parameter to calculate Output conduits with different number of conductors.

3. Click the [Shared Parameters] command under the [Management] option and create a new parameter named [Number of Wires].

4. Click the [Project Parameters] command under the [Management] tab, select the [Number of Wires] just created in the pop-up dialog box, and check [Wires] in the category Pipe] and set it as [Instance Parameter].

5. At this time, there is a parameter [Number of Wires] in the instance properties of the wire tube. Enter the number of wires for each wire tube according to the actual situation

6. Create a line pipe schedule and add fields.

7. Click the [Calculate Value] command, set its name to [Wire Length], and enter the formula [Length × Number of Wires] to complete the creation.

(Note: At this time, you can see the statistics of wire length in the detailed table. However, the wire length calculated by this method is still different from the actual value, because there is no Calculate the length of the line pipe fittings, and the final value needs to be increased by a certain proportion)
