3D Roof tiles in Revit

July 20, 2012

As Architects and Designers I must say that we have never been happy with the way Revit handles roof tiles.  While a surface applied pattern may work well for roof plans a flat surface has never looked good in 3D views and can often look funny in elevations. I have witnessed other extreme crazy work arounds which range from from placing single tiles to custom array families. All have a tendency to madden ones patience and can takes a hit on performance.

Recently I stumbled upon Jay Holland’s blog: BIM Aficionado and was very pleased when I found his posts on this very subject.  Jay posted an elegant (but not perfect) solution to 3D roof tiles. He has even posted a sample file and families to get us started. You can find his original post here: http://bimaficionado.blogspot.com/2012/07/pattern-based-curtain-panel-roof-tile.html

It does take practice but his families and methodology work well compared to most other methods.

Design By Many

January 24, 2011

If you haven’t seen it you should head over to Design By Many.  It’s a new social modeling competition site.  Even if you don’t decided to compete for some of the awesome prizes in the sponsored competitions the submittal source files are free and worthwhile to download.  If you pick apart the models you are sure to learn a thing or two about modeling in Revit or other industry standard software.

The latest sponsored competition was to design an external shading element for a downtown Phoenix structure.  Apparently I couldn’t help myself one night as I started designing a solution.  It’s not perfect but you can see (and please vote!) my submittal here. I invite you to take the sail array models apart.  You will learn a thing or two about Revit families and 3D arrays.  I think I nested the sail family 5 families deep! My custom truss family is based on a 3D void shape which has extrusions along the void edges.  It makes for some very easy modeling of complex sweeps.

Arrays Less Than 2?

July 6, 2010

Carl found this interesting post over on the Malleristic Revitation blog site. In fact, Carl will demo this during the next SARUG meeting.

Arrays Less Than 2?
Recently someone on AUGI was looking to array an element in a family, but the array kept collapsing when the value got pushed down to less than 2. It is unfortunate that Revit will not “store” a dimension between the first element and the hypotehtical second (in case the second goes away) but cest la vie.
