Do any of the Pix4D applications have tools to created 3D models of pipes, for example, a pump station?
Hey Tyler, are you interested in digitizing proposed features or is it more producing a 3D point cloud and map of the existing conditions of the pump station?
If you want to digitize existing features you can use the distance measurement tool to digitize the path of a pipe.
If you want to digitize proposed features, there is no tool available, but you can manually place points with known coordinate locations that you calculate. Use steps 2 through 8 in https://support.pix4d.com/hc/en-us/articles/202560279 to relocate the vertices of a distance measurement tool to digitize a proposed pipe.
You may be better off exporting your final point cloud into CAD software to digitize, as another option.
