Dynamo Revit Code Block

The code block has access to all of the dynamo nodes and can define an entire graph in one node.

Dynamo revit code block. In this case the parent code block is readily accessible and can be located anywhere on the graph. Dynamo basics 13 revit 10 bim management 2 revit advanced 4 revit basics 2. Read this chapter closely as the code block is a fundamental building block of dynamo. Strings formulas and other data types.

Logic or more specifically conditional logic allows us to specify an action or set of actions based on a test after evaluating the test we will have a boolean value representing true or false that we can use to control the program flow. 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. Functions can be created in a code block and recalled elsewhere in a dynamo definition. You can input code to represent letters numbers a sequence and much more.

Add some sliders to the code block inputs which range from 50 to 50. In the second line of the code block we define a shorthand to replace the number sequence node. Numeric variables can store a whole range of different numbers. Call the function with another code block in the same file by giving the name and the same number of arguments.

During this exercise notice how we use code block and existing dynamo nodes in tandem. The revit connection 8 2. Look mom no wires find these. This creates another layer of control in a parametric file and can be viewed as a text based version of a custom node.

The variables x and y are inserted into the code block so that we may update these dynamically with sliders. The code block is your bread and butter node for your dynamo scripts. With code blocks a user has the flexibility to decide. This way we can span across the default dynamo grid.

Code block part 1. This image was not altered. This lesson will take the power of the code block a step further. Code blocks and designscript.

By selecting the list at index 1 we see the data structure highlighted in the dynamo preview. A complicated dynamo graph from earlier in this course will be reduced to a few code block nodes using design script and functions. The revit connection 8 2. It works just like the out of the box nodes in your library.

Double click anywhere on the canvas to create a code block. Coordsxy 50. Notice that the code blocks defining the index for these two nodes are 1 and 2 which matches the original query from the code block points 1 2. The code block is a unique feature in dynamo that dynamically links a visual programming environment with a text based one.
