Tutorial
To use this app, select a linear element such as pipe, wall, duct, beam, or line and run the app. Click the button corresponding to how the element should be moved. Some logic is applied to elements that cannot be moved in certain ways.
This is an example from a pipe that is already horizontal:


Price
$10 per seat. 15-day money back guarantee. One year of updates are included.
Known limitations
Slope and end elevation parameters are not updated on pipes, ducts, or cable trays when they are made rectilinear with this app.
Workaround: nudge back and forth, or cut and paste-aligned the affected element and the slope parameter will update. To make a sloped pipe horizontal, it may be better to set its slope to 0 through Revit’s user interface.
Units shown in the dialog box are in decimal feet, Revit’s internal format.
