RhinoBIM_Structure has been released as a Work In Progress. We want to tell you in a series of blogs about our efforts in development that will make this a successful product.
We recognized, as many have, of Rhino’s capabilities and strengths as a 3D modeling platform and we also recognized a need for Rhino to support a BIM platform for AEC. Working with Robert McNeel & Associates we pointed out that paramount for Rhino is the need to handle large modeling data sets. Something architectural design requires more heavily over mechanical part design because architects, designers and engineers need to work in a model that is the full assembly and that can become very large and detailed. McNeel’s staff responded by developing a “Light Extrusion Entity” in Rhino V5’s core. This will be the basis and key to the success of most all RhinoBIM modules we develop and is first to be implemented in RhinoBIM_Structure.
In a test we found that the reduction in data weight can be as much as 97%. Yes, that much! Let me put it another way. We took the Walt Disney Concert Hall structural line diagram model and hung a standard Rhino V4 extrusion on all 15,900 lines. The model was 598 MB (which is at least half the size we found in using competitor software programs that have parametrics and internally associated BIM data). Then using RhinoBIM_Structure with the light extrusion, that same model with the same structural shape is only 20 MB.
As you can see the Light Extrusion will significantly increase Rhino’s performance. As a side note, using the "select all LINE" function in RhinoBIM_Structure, all 15,900 shapes were hung in the model in 2 seconds. Yes, two seconds on an inexpensive Dell Latitude D620 and the viewing performance is fantastic.
With this capability alone we see users having the ability to model full projects within a single master data base. This will increase performance which equates to an increase in productivity. Something that is key to BIM and where other software programs have struggled to get to. We can't wait for you to get your hands on it.
