Vasari Talk: Formula Foo

2012-03-20_1433

I’m going to be leading our free webinar tomorrow (Wednesday), talking about using formulas in Vasari families.
Register now! Wed, March 21, 2012 11:30 AM - 12:30 PM EST

Questions on this topic? Post them here.

Summary: Parameterizing a dimension? Easy. The fun really begins when you manipulate and even create geometry using formulas.

  • Learning Goals: At the end of this session, you will be able to
    • Use basic Revit/Vasari formula syntax including conditionals, operators, rounding, and math constants such as sin, cosine and pi.
    • Use some simple formulas to manipulate a parametric massing family to explore various permutations
    • Reference parameters from a nested family in a formula

    Edit:  Let’s try something new.  I’m going to do something like this tomorrow.  You can watch ahead of time and then have questions for tomorrow.

    Vasari 2.5 released with converging line bug

    What’s wrong with this picture?2012-03-15_0913

    Well, for one, if you infinitely extend parallel lines running along element edges, they will either converge on a horizontal plane projecting out from the viewer, or at a vertical plane extending at a right angle to the the horizontal plane!

    2012-03-15_0914

    Shouldn’t it look like this?

    2012-03-15_0931

    I mean, come on Vasari! How hard is it to keep your lines parallel? Now my working views have all of this sense of depth and space. Urgg!

    AND, unlike Camera views, that are not editable, my perspective view is all cluttered up with dimensions and controls.

    2012-03-15_0916

    So now I’m all, like: “you want me DESIGN in this view or something!?!?”

    2012-03-15_0921

    Answer: Well . . . yeah. That’s kinda what we’re shooting for.

    Autodesk Revit is generally thought of as a documentation tool, a medium for expressing a completed design prior to construction. At its core, however, lies a parametric change engine - a relational database with a 3d user interface. In his book, Elements of Parametric Design, Robert Woodbury explores what it means to design in a medium that is highly iterative. Parametric ‘thinking’ underscores an old methodology of designing, which computers now simply enable and augment. In typical CAD (and BIM) packages, it has become relatively easy to create lots of geometry, but very difficult to iteratively change that geometry. This shifting and changing of data structures - as a response to design intentions and performance requirements - makes for the next generation of great design tools and is the backbone of advanced parametric design.

    This presentation will explore methods for creating advanced parametric design relationships that leverage traditional architectural design training with environmental (or ‘performative’) feedback. Geometric relationships are transformed into parametric building ‘representations’ without the need for complex coding or graphical algorithm editors. As an experiment, the speakers have created a new, free, technology preview called Project Vasari that allows for direct access to this parametric core and related modeling tools. In order to assess their new application, they have implemented 14 of the Design Patterns mentioned by Woodbury, all of which can be achieved without any computer programming or scripting skills. Their presentation will look at the results.

    Matt Jezyk is an Autodesk Senior Product Manager for AEC Conceptual Design Products. He has been in the Architecture and Engineering industry for 16 years and has spent the past 12 years developing Autodesk Revit. As one of the original architects hired by Revit Technology Corporation, Matt helped build what are now called Revit Architecture and Revit Structure. He is experienced in building both parametric and geometric modeling tools on the Revit platform but more recently has focused on emerging markets and technology. His latest development teams have produced new parametric modeling tools directly integrating energy analysis features. One such tool, Project Vasari, is available for preview on the website, Autodesk Labs.

    Zach Kron is an architectural designer and a quality assurance analyst for Autodesk. For the last five years, he has worked closely with Autodesk Revit Architecture product designers and developers creating and testing rendering, modeling, and analysis tools. In addition to internal teaching and curriculum development at Autodesk, Zach has helped create and run workshops at MIT and ACADIA, and maintains a personal blog on his work. Before joining Autodesk, he served as a designer in several Boston-area architectural offices, working on projects ranging from furniture to bridges. Zach has more than fifteen years of professional experience in virtual form making and visualization.

    Arc wall flattener

    2012-03-03_2214

    A great question the other day from some guys on the the construction end of things.  “Is there a way to make a flattened view of a wall that is an arc in plan?”

    2012-03-02_2154

    Yes!

     

    2012-03-02_2157

    The method is a combination of the Reporter and Projection patterns, a reading of one set of data (portions of the curved wall) and feeding that data into another place to recreate it in another context (flattened abstraction).

    “Re-present (abstract or transform) information from a model.”

    “Produce a transformation of an object in another geometric context.”

    You can download the 3 pick adaptive component here.  Basic rules for use:  pick the start(1), middle(2), and end (3) of the bottom of the arc wall, then pick the floating “shape handle” point and rehost it to the top of the wall above the end(3) point.  The representation of the flattened wall can be pulled around by a fifth point.

    But for those who want to understand it, please check out the longish step by step construction, 24 minutes.
