RhinoBIM - Structure

Představujeme RhinoBIM

RhinoBIM je souhrnný název pro několik plánovaných modulů, které zvyšují využitelnost Rhina 5.0 v oblasti architektury, inženýrství a stavitelství. Vyvíjí ho společnost Virtual Build Technologies LLC a první dostupný modul má nýzev RhinoBIM Structure. Tento modul slouží k modelování 3D konstrukcí, k analýze tolerancí a vůlí a ke strukturální analýze.

Using Rhino 5.0's new light extrusion technology, RhinoBIM Structure builds 3D structural design elements that are much lighter in data weight significantly decreasing model size.

With the light database the Clash & Clear analysis finds errors within seconds and there is no need to export the model to another program to perform the analysis.

This beta version is now feature complete and the final version is expected to be released later this year.

RhinoBIM Structure Features:

• RhinoBIM components are compatable with Grasshopper
• Robust tools for adding and editing structural steel beams
• Extensive library of steel shapes, including international standards
• User definable steel shapes
• Assign materials, attributes, and process treatments to each element
• Data extraction through translators for CIS2 and Beam to NURBS
• Very fast Clash & Clear analysis
• Very large model support using new Rhino 5.0 technology

Additional Structural Analysis features

• Automatic meshing
• Commercial and freeware solver options, including ANSYS
• Full pre and post processors within the Rhino modeling environment

RhinoBIM is a series of BIM plug-ins for Rhino 5.0 from Virtual Build Technologies
LLC. The first modules, Structure, Clash & Clear and Analysis are now available. This
work-in-progress version is nearly feature complete and is expected to be released
later this year. Everyone is invited to download it now.

Features include:

• Robust tools for adding and editing structural steel beams
• Extensive library of steel shapes including the international standards
• User definable steel shapes
• Assign materials, attributes, and process treatments to each element
• Extract data for downstream application including structural analysis, detailing, cost estimating, scheduling, staging, and fabrication
• Very fast clash and clearance analysis
• Full pre and post processing for analysis with Rhino modeling environemnt
• Very large model support using new Rhino 5.0 technology

We used CATIA for 28 years beginning with version1 in 1982 and actually introduced computer design to Frank Gehry's office and developed the methods and techniques used by his office beginning in 1991. Many of the techniques such as using a master 3D model for design through construction, for fabrication, 4D and 5D were pioneered by us on numerous projects.

When CATIA V5 was announced which became Digital Project in 2003, we did not like this completely new software program. As you recognize it is too complicated for architecture (design by Boeing written by Dassualt specifically for aircraft design), its too expensive and too hard to master. We found Rhino V4 to be very much like the CATIA which we used on all of Frank's work up until 2003. Contrary to what many have been led to believe Digital Project was not used on the Walt Disney Concert Hall or other previous projects at Gehry's. Gehry Technologies, a separate company from Gehry's design office markets Digital Project but as many people don't know Rhino is used within Frank Gehry's office as a design tool.

We contacted Bob McNeel and discussed how, with our experience and background we could enhance Rhino with the same functionality we used in CATIA for architecture all those years. He agreed and we have teamed up with them. We see Rhino becoming the 3D master design modeler. It has the ability to build complex geometries. We recognized it needs the main components such as Structure, HVAC, Concrete, etc. We are nearly complete with Structure. The other programs follow the same methodology and can be programmed much faster. There is also an effort to build a library of doors and windows. With these components we will have the capability for users to attach information to the objects and then query, organize and total the information. Also as you mentioned we are working on a collaborative management tool to facilitate multiple users working within a project in Rhino.

Rhino has Grasshopper as its parametric tool and we will be interfacing with its capability. But I think you should investigate further the use of parametrics in general. There is a general misunderstanding in the industry with the thinking this capability is paramount to a project. Parametrics is a function to help productivity. If not used properly it can actually degrade the productivity of a project and quality of the model. Go to our company page and read about our experience with parametrics: http://vbtllc.com/index_rhinobim.html specifically link to the white paper by PTC and our technical notes. Parametric Technologies Corporation (PTC) was the company that introduced parametrics to the market in the mid 1980s. Ex-PTC employees began writing Revit and Digital Project is based on the PTC concepts. In PTC's white paper they found that this approach does not work well with custom, highly complex designs. PTC now markets an approach called explicit modeling which is the approach Rhino uses. There is a proper use of parametrics.

I hope all this information helps in your decisions. We would very much like your input to help guide us in our efforts.
