- 3. 3 DYNAMO REPORT 1. Introduction 1.1. What is Dynamo Dynamo is primarily a plug-in for Autodesk Revit and Vasari. Dynamo can also run as a stand-alone application with all the list and logic functionality, and with some experimental geometry tools available using the Autodesk Shape Manager kernel. Dynamo allows designers to design custom computational design and automation processes through a node-based Visual Programming interface. This means that a designer can leverage computational concepts, without the need to write code. In addition, Dynamo gives the designer the added advantage of being able to leverage computational design workflows within the context of a BIM environment. The designer is able to construct custom systems to control Vasari Families and Parameters. 1.2.

Nodes Nodes have input Ports on the left side and output Ports on the right side. Directionality of execution and program flow usually goes left to right. Nodes are the objects you place and connect together with Wires to form a visual program. Nodes can represent Revit Elements like Model Lines or Reference Points. Nodes can also represent operations like Math Functions. Nodes have inputs and outputs. The colors of Nodes change to indicate state. con con ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn con con c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c 4 Part A: Pulldown Menus Part B: Search Bar Part C: Node Library Part D: Workspace Part E: Execution Bar 1.3.

- 5. 5 1.3.2. Wires Wires connect between Nodes to create relationships and establish a program flow. You can think of them literally as electrical wires that carry pulses of information from one object to the next. You create a Wire using the mouse left-clicking on an output Port and dragging with the mouse button held down, then connect to the input port of another node. To disconnect a Wire, left-click on the output Node and pull the Wire away. 1.3.3. Ports Ports are the light rectangular areas on Nodes, they are the receptors for Wires. Information flows through the Ports from left to right. Inputs Ports are on the left side of the Node. Outputs Ports are on the right side of the Node. con con ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn con con c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c 5 1.3.2.

In short, code blocks are a text-scripting interface within a visual-scripting environment. They can be used as numbers, strings, formulas, and other data types. The code block is designed for Dynamo, so one can define arbitrary variables in the code block, and those variables are automatically added to the inputs of the node: Query action: con con ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn con con c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c 11 have a one-to-one relationship with the scripting language, there are unique opportunities to move between node-based interactions and scripting in a fluid way.

In the examples below, we're isolating a variable from the primary range notation, and creating another range of that list. Creating nested ranges, compare the notation with a "#" vs. the notation without. The same logic applies as in basic ranges, except it gets a little more complex. By controlling the "end" value in a range, we create more ranges of differing lengths. 2.6.

- 41. 41 Make the lists in order to create lots of curves and paralell to original curves. Curve.EndPoint: get the end point along the curve. PolyCurve.ByJoinedCurves: make polycurve by joining curve. Flips curve as needed for connectivity. Curve.Length: the total arc length of the curve. Geometry.Translate: translate any given geometry by the given displacements in the x,y,z directions. Use Curve.Offset node to create a set of new curves with a specified amount. Note that, in this case we use Math.Sin() function for making a different offset. con con ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn con con c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c 41 Make the lists in order to create lots of curves and paralell to original curves.

- 44. 44 4.8.2. Creating Revit Elements To create the floor element, we use some nodes: Curve.ApproximateWithArcAndLineSegments: approximate a curve with a collection of Arcs and Lines. Floor.ByOutlineTypeAndLevel: create a Revit Floor given it’s curve outline and level. To create the level, we use the node named Level.ByElevation. con con ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn ghebim.vn congnghebim.vn congnghebim.vn con con c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c hebim.vn congnghebim.vn congnghebim.vn c 44 4.8.2.
