  Ellipsis Representin' at Autodesk University
  October 16, 2009 01:01 PMby Rob Cohee

  I know, it’s a rough assignment…Vegas every year, classes, crowds, food, fun – whoa is me… HA! I love Vegas it never gets old. Remember when we had it in Orlando? I took the kids…happiest place on earth my – anyway back to the point. The MFG Technical Evangelist team will all be representin’ this year at AU. You’ll be able to track us down at the Manufacturing Lounge, and the Community Pavilion, and of course our classes. Each of us have at least two classes and they break down as follows:
  Jay Tedeschi
  MA118-5 Digital Prototyping: The Rosetta Stone
  http://au.autodesk.com/?nd=e_class&session_id=5396
  Class Description: The Rosetta Stone was instrumental in gaining an understanding of Egyptian hieroglyphic writing. Today that term has become synonymous with something that is a critical key to decrypting or translating a difficult problem. This class will help you understand the Digital Prototyping process, and how it is more approachable and attainable than you may think. You already have the tools. Now we are going to show you how to use them.

  MA208-4 Surface Modeling From A to Z with Autodesk Inventor 2010 
  http://au.autodesk.com/?nd=e_class&session_id=5392

  Class Description: We will focus on a look at surface modeling from the ground up with Autodesk Inventor 2010. Improvements to the sketching environment, especially those dealing with splines and their effect resultant surfaces, will be explained and demonstrated. Different approaches to building surfaces, and ensuring that the desired surface properties (e.g., curvature, tangency, etc.) are maintained, will be emphasized. Best practices with regard to all of the elements of a successful surfacing strategy will be stressed throughout.
  Rob Cohee
  MA122-3 The Convergence of BIM and Digital Prototyping
  http://au.autodesk.com/?nd=e_class&session_id=5176
  Class Description: Building product and equipment manufacturers are on the front lines of both building information modeling (BIM) and digital prototyping. When strategically applied, BIM and digital prototyping complement each other to the extent that the information required to create and relay architectural and engineering intent as well as manufacturing, construction, and assembly levels of detail occur as a matter of consequence, and not as a reinterpretation of intent at each phase of construction and manufacturing. This class will explore how building product and equipment manufacturers can utilize the Autodesk portfolio of software products to collaborate with architects, engineers, and builders in the fluid exchange of BIM-ready design.
  MA318-1 Building Fabrication: A Peek Behind the Curtain…Wall
  http://au.autodesk.com/?nd=e_class&session_id=5184
  Class Description: Increasingly ambitious building designs, the growing technical complexity of modern building envelopes, concern for more sustainable design, and mounting economic pressures are all leading the building industry to seek more efficient processes that improve predictability and control within a building project. The fabrication of building components is becoming increasingly prevalent in architecture, thus challenging ideas as to what is possible, how project information is created and consumed; and challenging the overall building industry to reevaluate its processes to become a more predictable, sustainable, and environmentally responsible business. This class will illustrate how Autodesk is addressing the digital exchange of design intent throughout the building process.
  Justin Hoey
  MA314-3 Improving a Da Vinci Design Using Autodesk Inventor
  http://au.autodesk.com/?nd=e_class&session_id=5098

  Autodesk Alias Design - From the Beginning Lesson1 - Part 4
  October 14, 2009 01:10 PMby Chris Hall

  This video covers creating a project directory structure in Autodesk Alias Design. By using a the proper directory structure your files are organized correctly and you are less likely to have missing file links as your project matures.
  
  
  
  

  User_data

  The user_data directory is created by Autodesk Alias Design and will be re-created if you delete it. If you store all your data in the user_data directory, then it will be easy to locate and organize using the Autodesk Alias Design file tools.

  However, you may want to store your data on a network server, or a memory stick. This is no problem, but it is advised that you create your own user_data directory and keep the project structure the same underneath.

  Project

  The idea of a Project is important because an AliasStudio model file may contain many different types of information, which reference each other, in particular images (pix) and geometry (wire).

  Wire Directory

  This is the directory you will use most of the time, and it is where you store your geometry files. However, a geometry file that is used for rendering or concept sketching will reference image files, which will be stored separately in the pix directory.

  Pix Directory

  The pix directory is where you will store images that you reference (texture files, sketches) AND images that you create (renderings).

   

  The Concept of a Current Project

  As you do more work in AliasStudio, you will have more and more projects. To make life easier for yourself, you can tell AliasStudio which one is your current project. This will then become the default for all your saving and filing. Most importantly though, it is where any crash files will be saved, so it is useful to know where to go and look for the saved data.

  Current Project and Image File References

  Another good reason for setting the Current Project is the pix directory of the current project will be the default location where AliasStudio looks for the image files.

  New Project

  The New Project button simply creates a directory with all the subdirectories. You will need to rename the project as it will be given the default name of ‘new_project’.

  The same, but different...
  October 1, 2009 09:30 AMby Jay Tedeschi

  The same, but different... let me explain.  So, the same problem we were discussing for the last couple of weeks, namely, working with data from other sources.  If you recall, I had covered working with data from a vendor from whom I was buying components for our re-design.  This week, the problem is the same, but different in that in this case I am working not with a purchased component, but rather with an assembly that was created with a different design tool than the one I happen to use.

  In the best of conditions, this presents something of a challenge, but when we find ourselves needing to change the design in some way, the level of complexity quickly increases.  Autodesk Inventor Fusion was built from the ground up to facilitate the toughest of these type of design challenges.  In this, the first of several posts featuring Inventor Fusion, we will take a look at some basic assembly manipulation and modeling techniques.

  If you remember last week we finished up working on the Caster Wheel "Assembly" that we downloaded from our vendors web site.  Well now we are going to work on the brake assembly that attaches to two of those wheels... this was originally created in Pro/E, which is not a problem for us as we can open the .asm file natively.  Once open we can see that the existing torsion spring is not going to work in our new configuration, so we will select the body from the assembly, and then from the marking menu select "Isolate" to suppress all but the spring.

  

  I can now make several non feature based edits to this part, quickly and easily.  As these changes are symmetric, I will split the part, then correct for rotation and position with the Move command.  Here I am moving the body along its mount axis so that it fits correctly in the bearing block.

  

  Now we can address some of the feature lengths, but again, not via a feature edit, but rather with a direct manipulation of the feature face.  For example, as you can see in the figure above, the length of this element is a bit more than is required, so Press/Pull functionality is used to select the capping face and then press into the model, shortening the element.  As we split and then moved the entire body away from the center plane of symmetry, the split face is now short of the center plane by the amount of that first move.  Press/Pull is used here again, but in this instance I will select the symmetry plane after picking the capping face, and the pulled face "snaps" to that plane.

  

  Finally, the corrected spring is mirrored about the symmetry plane and the assembly saved for use back in the top level assembly.

  

  The thing that really hits you with Fusion is how absolutely easy it is to use.  The entire edit sequence shown above took no more than a couple of minutes... Don't take my word for it... check out the entire session for yourself in this video I shot.  As always, if you have any questions or suggestions I would love to hear them.

  Ciao'
