How to Arrange Trees Along Specified Line Segments Using Dynamo

In daily project site layouts, arranging trees, flowers, and streetlights along both sides of a road is a common task. Manually placing each component can be time-consuming, especially when dealing with numerous items. This guide explains how to use Dynamo to quickly and efficiently place components along specified line segments.

1. In Revit, start by creating a curve. This can be done by drawing model lines to define the path along which you want to place the components.

2. Open Dynamo (using version 0.9 as an example). Select the curve you just created, then generate points along it where the trees will be placed. Below are key nodes and their functions used in this step:

• Select Model Element: Choose an element from the Revit document — in this case, the curve you drew.
• Element.Geometry: Retrieves all geometric information associated with the selected element, linking the model lines to the components to be placed.
• Curve.PointsAtEqualSegmentLength: Returns a set of points evenly distributed along the curve, based on the specified number of segments.
• Code Block: Allows you to input custom code directly; here, it controls the number of points generated along the curve, as shown in the example.

3. Next, place the poplar tree components at the points generated along the curve.

• FamilyInstance.ByPoint: Places family instances (from the selected Family Types) at the coordinates obtained from the points on the curve.
• Family Types: Lists all available family types in the Revit document. Select the desired family, such as poplar trees, as demonstrated in the example.

4. Once completed, the trees will be arranged neatly along the curve, as illustrated in the corresponding figure.

5. After finishing the setup, the overall Dynamo interface looks as shown in the figure.

Summary: Dynamo integrates seamlessly with Revit, enabling you to generate and manipulate models through automated calculations reflected directly in Revit. This example demonstrates a simple but effective way to quickly place tree components along a path. In practical projects, Dynamo can similarly be used to generate other elements such as bridges, optimizing workflows and improving efficiency.
