About
ThePipe is a platform intended to provide real-time geometry exchange between different design and modeling applications, or different instances of the same application. These applications could be on the same machine or on different machines. The geometry in these different applications can stay synchronized in real-time. For example, you could have lines generated in Grasshopper actively driving a wall profile in your Revit model, or similar real time links between any two of the supported applications.
Supported applications: Rhino, Grasshopper, Revit and Dynamo.
Note: There are limitations--some primitives are not supported.
