CAD definition in a BIM world ...and a few words about Risa Structural Analysis

Creation

         Action

                    Decision



....then I heard this one....BIM

        (B)rings (I)n (M)oney


One of my earlier definitions of CAD was (C)oordination (A)nalysis (D)esign.

Last night I became a dealer of Risa structural analysis software.  They're a Design and Analysis software company that's been around since 1987.  They're another company that's been doing BIM before it was BIM.  

Let's add "Create" to their workflow, so we have Create-Analyze-Design.  

Wouldn't you like to be able to run a study of which would be more beneficial to your client?  Wouldn't it be nice to do a comparison of a steel versus concrete building, see which is more economical and which could be erected faster?  You know...just like Design/Build contractors are doing right now with BIM?  Wouldn't you like to actually provide real services to your clients like pricing, design options and scheduling efficiencies based on building type?

I hope you realize how the CAD process is causing your industry to implode because of your insistence that CAD is equal to or better than the BIM process and software.  Why are some of you so stubborn and resistance to something new for a change?  

What you're essentially doing is Calligraphy Annotated Drafting.  Yes, calligraphy.  You may as well be drawing your lines circles and arcs by hand with a fountain pen for all the time it takes to make your line weights and hatch patterns look pretty.  Is that what you promised the client in your AIA contract?  That you'd give them a bunch of pretty lines?

Wouldn't you rather be part of an AIA IPD A191 contract where you're actually part of a team building a building?  Are you a builder or a drafter?  


 If you'd like more information about BIM or Risa, please contact me.  I'm officially a national dealer for Risa so at least let me get you some pricing.


RISA-3D Integration http://risatech.com/p_integration.html

RISA-3D is the heart of the RISA Building System, integrating with six other RISA programs to offer a complete structural solution.

RISAFloor + RISA-3D + RISAFoundation

RISAFloor designs a building quickly with a graphical interface that allows you to lay out your columns, beams and walls floor-by-floor.
The integration between RISAFloor and RISA-3D allows you to design the gravity system in RISAFloor and take the lateral system into RISA-3D to design for wind and earthquake loads.
All the reactions from the gravity and lateral members are brought into RISAFoundation for design of the footings, slabs and grade beams.http://risatech.com/images/integration/image-3dFloorFound.png

RISA-3D + RISAFoundation

The integration between RISA-3D and RISAFoundation allows you to use your base reactions from any RISA-3D model to design mat slabs, combined foundations, spread footings and grade beams.http://risatech.com/images/integration/image-3dFound.jpg

RISA-3D + RISATower

In RISATower you can build a complex geometry tower or monopole quickly with all the tower loading automatically applied. The integration from RISATower to RISA-3D allows you the freedom to add additional structures beyond the tower such as candelabras. With the model in RISA-3D, you can view your tower using the powerful RISA-3D graphical interface. RISA-3D can check the tower for international steel codes as well as perform a dynamic analysis.http://risatech.com/images/integration/image-3dTower.jpg

RISA-3D + RISA-2D

Model a component of your structure such as a frame or truss within RISA-2D. You can then import your 2D structural component into RISA-3D and add additional members to create the full model. Append multiple 2D components to create a complex structure.http://risatech.com/images/integration/image-2d3dInt.jpg

RISA-3D + RISAFoot

The integration between RISA-3D and RISAFoot allows you to design your spread footings in the same model as your super structure. The reactions from your supports are automatically applied to the footings. Design rectangular or square footings including the pedestal design.http://risatech.com/images/integration/image-3dFootInt.jpg

RISA-3D + RISASection

The integration between RISA-3D and RISASection allows you to bring built-up sections into your RISA-3D model (even multi-materials!) and solve for accurate forces and stresses. http://risatech.com/images/integration/image-3dSection.jpg

Hey, Greg. We use RISA, and have recently started to get into Revit Structure. Do you have any resources showing how well (or poorly) RISA and Revit collaborate? Do you have an opinion as to whether we should stick with RISA or if it would be worthwhile moving to RST?
