Method for Manufacturing Revit Ramp Spray Pipe
Curved pipes in Revit have always been challenging, especially when they need to be created on a spiral ramp. This task can be particularly frustrating because it cannot be accomplished through standard layout and volume methods, as the pipes do not connect properly. However, there is a simple and practical alternative for managing directional changes. Let’s explore this method.
1. Create Auxiliary Lines
Using the spiral ramp model we established previously, start by creating two auxiliary lines to locate the center of the circle.
Next, draw a circular arc to position the main spray pipe accurately.
Additionally, draw an auxiliary line at the end of each branch pipe to assist with precise positioning.
2. Create Spray Branch Pipes
Start by drawing the branch pipe along the fan-shaped auxiliary line. Pay close attention to the elevation to ensure accuracy.
It is recommended to raise the top range of the view to make future adjustments easier.
At the connection point with the straight main pipe, connect one end of the branch pipe first, then increase the elbow size as needed.
Click the +control option to convert the elbow fitting into a tee fitting.
Leave the fittings for the middle branch pipe in place temporarily, then delete any excess pipe segments.
3. Connect the Spiral Main Pipe
This is the most crucial step: creating a spiral-shaped main pipe.
In Revit, the only pipe type that can be drawn as an arc and twisted in 3D space is the Hose pipe.
However, drawing the hose directly won’t produce the desired result, which is why the previous setup was necessary.
Now, simply adjust the pipe diameter and use these hose pipes to connect the fittings.
If you create the fittings beforehand, the default connection curvature will be closer to what you need.
4. Adjust Hose Control Points
When viewing in 3D, you may notice that the curvature is still slightly off.
This can be fixed by dragging the hose’s control points.
By default, control points appear at both ends of the hose, and additional vertices can be inserted by right-clicking on the hose.
