The Electrical Schematic command button is found in the GTP WireWorks ribbon panel on the Add-Ins tab inside Revit. |
Load Feeder Schedule
When first loaded on a new project, the schematic diagram will be empty. To begin, select an import configuration from the drop list and then click the Load Feeder Schedule button.
When pressed, a file selection dialog will be displayed, prompting for the feeder schedule spreadsheet to associate with this Revit project.
| Info |
|---|
| It is important to note that the drop list next to the load feeder schedule button is where the feeder schedule import configuration is specified. Set this option prior to clicking the Load Feeder Schedule button. |
Expand/Collapse Nodes
While hovering over a node with the cursor, a checkbox on the left side appears which allows collapsing of child nodes in the display. Once collapsed, an ellipsis will display to indicate child items are available but not currently visible. This setting is not saved with the file.
Manually Reconciled Nodes
While hovering over a node with the cursor, a checkbox on the right side appears which allows the node to be marked as manually reconciled. Once marked, a checkmark is displayed. Connecting conduit runs will display as reconciled as well once all sets have been defined. This feature is useful when working with a linked Revit model where the panel resides in the linked model and cannot be modified by the user. This setting is stored with the file.
| Info |
|---|
| There is a related setting for 'Include Linked Models' which supports reconciling panels that reside in a linked Revit model with the feeder schedule. |
Rood Node Selection
This drop list contains all root nodes found in the feeder schedule. When changed, the schematic diagram will be reloaded.
| Info |
|---|
| Selecting the < SHOW ALL NODES > option from the list will display all root node diagrams side-by-side in a single view. |
Reload Feeder Schedule
Reloading the feeder schedule is the manual method of forcing the diagram to be refreshed. The feeder schedule spreadsheet previously assigned to this project will be read and reconciled with the Revit model, causing the diagram to be refreshed.
| Info |
|---|
| A tooltip when hovering over the reload button will display the feeder schedule Excel file path. |
Export Schematic Information to Feeder Schedule Excel File
The export function will write conduit total lengths, summed for all parallel runs, back to the feeder schedule spreadsheet. A field mapping for Total Conduit Length is required to be present in the feeder schedule import configuration.
The wire length exported to the feeder schedule will be the total circuit length for a single wire with makeup included.
| Info |
|---|
| The spreadsheet is responsible for formatting the cells to display the numeric value in feet and inches or other desired format. |
The export function will also write out all connections found as Revit-only content during model reconciliation. This will include electrical equipment with panel names connected via Revit circuiting, which didn't previously exist in the feeder schedule spreadsheet. These rows will be added to the next blank row in the spreadsheet.
| Info |
|---|
| Starting from an engineer's Revit model which includes circuits, it is possible to export the model to a feeder schedule. The procedure is to start with an empty spreadsheet and defined feeder schedule import configuration. Load the empty feeder schedule spreadsheet into the Revit project and then use the Export schematic command to save the model data out to the spreadsheet. Once saved, GTP Electrical will prompt you to reload the feeder schedule. Click Yes and then the model will be synchronized with the feeder schedule spreadsheet. |
Export Schematic Diagram to FSD File
A file save dialog will appear where the output feeder schedule diagram file name can be specified. Click the save button to save a snapshot of the current schematic diagram.
| Info |
|---|
| The GTP Schematic Viewer application is available to share diagrams with other members of your team. |
Export Wire Length Report to XLSX File
A file save dialog will appear where the output wire length report file name can be specified. Click the save button to save and open the report in Excel.
This report also contains summary pivot tables for both conduit and wire with totals provided and organized by size and type.
Percent Complete
The percent complete is the percentage of nodes and connector runs read from the feeder schedule that has been successfully linked to and reconciled with Revit content.
Nodes are considered to match if there is a one to one match of panel name or room number to a part in the Revit model.
Connectors are a bit more complicated. They must have matching From and To parameter values and have physical connections (based on tolerances) to the referenced electrical equipment or rooms they specify. They must also have the correct quantity of parallel runs to match the number specified in the spreadsheet.
| Info |
|---|
To further complicate conduit connections in the Revit model, junction boxes are detected as electrical equipment with an empty panel name. From and To connections may traverse one or more junction boxes and will be considered to be connected based on tolerances specified and applied to junction boxes. |
Schematic Nodes
The nodes represent electrical equipment or rooms from the feeder schedule and Revit model. The Categories specified in shared settings control which additional Revit categories are considered Equipment nodes. Valid parameter names must be set up for the Panel Name to be recognized.
Here are the available node border and fill color display options:

Schematic Node Tooltip
Notice in this example, the node has a small (i) in the bottom right corner. This indicates the panel or room appears more than once on the diagram due to the way the feeder schedule is defined or data from the Revit model.
Schematic Connectors
The connectors represent electrical conduit runs connecting the equipment to equipment or rooms as specified by the feeder schedule.
The connectors can have various line colors, line widths, and line types depending on the Revit model reconciliation results.
Here are the available connector line display options:
Here are the available connector bubble display options:

|
Schematic Connector Tooltip
Notice in this example, the connector bubble displays 4/6, meaning 4 of 6 required runs have been reconciled with the Revit model. The tooltip displays details for each parallel run. The Conduit Length is a total length of conduit for each parallel run. It may be the sum total of multiple runs when junction boxes are present. The Bend Angles is a total for each independent run that makes up the parallel run. When junction boxes are used, there will be more than one total for bend angles. The Junction Boxes is simply the number of junction boxes found for each parallel run.
Reconcile Warnings
When the feeder schedule import configuration includes Revit parameter name mappings for the fields, GTP WireWorks will reconcile the values found in the spreadsheet with the parameter values for electrical equipment and conduit in the model. This applies only to parts where the parameter can be found. In the case a parameter value is found which doesn't match, there will be a warning indicator icon displayed in the schematic diagram. By hovering the mouse cursor over the warning icon, a tooltip will be displayed indicating the parameter value(s) which don't match. Here's an example showing how that works.

Schematic Sample
Here are the details we can extract from this sample schematic diagram:
1. SWGR and Lighting have not been placed in the Revit model.
2. The red connector from XFMR to Branch 1 indicates the conduit's total bend angle is > 360 degrees.
3. The connector bubble displaying 6 indicates there are 6 parallel conduit runs connecting Branch 1 to Room 2, satisfying the feeder schedule requirement.
4. The Room 2 node displays an (i) which indicates the node appears more than one place in the diagram. In this case, it indicates an error.
5. The blue dashed connector from Branch 2 to Room 2 displaying 1/0 in the bubble indicates there is a conduit run in Revit which doesn't match anything in the feeder schedule.
6. The connector bubble displaying 1/6 with a dashed line indicates there is only one of 6 conduit runs currently in Revit connecting Branch 2 to Room 3.
Redundant Schematic Sample
Below is a sample of the standard redundant power layout. The line shape is adjusted to minimize overlap and annotation locations above redundant connections are in the middle of the line like above XFMR1-1.
If a piece of equipment has only one feed, the annotation will be directly over the fed equipment like XFMR2-1
