GeoPipes is a Blender Addon that allows you to generate procedural Pipes by using Geometry Nodes.
The core of the addon is Geometry Nodes but the addon makes it much more convenient by offering the ability to create pipes in the Object mode by simply clicking on surfaces.
Installation:
Go to Edit>Preferences>Addons>Install and select the zip file you downloaded.
GeoPipes Panel is located under the ‘A-Tools’ section of the N-Panel
Click the ‘Create Pipes’ button to start the drawing mode.
Click on any face to place a point and keep clicking to add more points.
Hold down CTRL to snap the point to the center of the face.
With any GeoPipe object selected click the Edit Pipe button to extend the pipe further while keeping the existing points intact.
With any GeoPipe object selected click ‘Add Shipped Connectors’ to add the 4 connectors shipped with the addon to your Pipe.
GeoPipes comes with these 4 Connectors.
For more controls, you can use the GeoPipes modifier which is added to all GeoPipe objects.
Requires Blender 3.0+
