Abstract: Executing a graph. A method includes identifying that a graph includes one or more nodes having input ports that are coupled to alternative inputs. The method further includes identifying permutations of inputs where each permutation uses one of the alternative inputs. The method further includes executing the graph for each of the identified permutations. The method further includes identifying a metric for each execution of the graph for each of the permutations. The method further includes providing a user with an indication of the metrics.

Abstract: A method, system, apparatus, computer program product, and computer readable storage medium provide the ability to define an object in a parametric modeling application. Geometric parametric objects are authored and organized into a family definition. Via a user interface, enhanced computational logic is defined. The logic is compiled into the family definition such that the enhanced computational logic is embedded at an object level of the one or more geometric parametric objects. Upon a building information model requiring a regeneration operation, the compiled enhanced computational logic is automatically executed.

Abstract: Methods and apparatus, including computer program products, for providing a computer aided design (CAD) model comprising a plurality of physical elements. An analytical representation of the plurality of physical elements is generated. The analytical representation comprising a plurality of analytical elements corresponding to the physical elements. An association between each analytical element and corresponding physical element is generated such that a modification to one element can be applied to modify a corresponding other.

Abstract: Systems and techniques to provide for software installation. In general, in one implementation, the technique includes providing a first model, the first model being one of: a massing computer aided design (CAD) model or a detailed CAD model; providing a second model, the second model being an other one of: the massing CAD model or the detailed CAD model; and creating a first object in the first model based on a feature of a second object in the second model.
