Generate String Lights
In this chapter, we are going to sample a few of the plugins that come with FormIt to make some improvements to the Encode Campus Sample Model.axm. If you have not already, you can download the file from the FormIt Primer Part II DataSet__
This neat plugin lets you quickly add hanging lights to your model based on a line or curve.
1 - Before adding any new lights, let's check out the intended result using a premade scene in the model.
To jump to the scene containing existing string lights, open the Scenes Palette and double click on the scene named Eye Level – Short Alley.
Notice the string lights that came with this model – that is what we are going to recreate, but somewhere else.
In the Layer Palette, turn on the Helper Geometry layer so you can see the original lines used to generate these string lights.
2 - Now let’s navigate to the other alley and add some lights. In the Scenes Palette open the Eye Level – Long Alley scene. Notice that this alley does not yet have any string lights.
3 - To create a new string of lights:
Open the newly installed Generate String Lights Palette by clicking on the string light icon. By default, the icons for new plugins appear at the bottom.
Change the Number of Fixtures option to 10.
Double-click on one of the helper lines to edit the pre-created String Lights – Long Alley group. Then single-click on one of the pre-drawn helper lines to select it.
Click the Generate String Lights button inside the plugin’s palette, and a new string of lights should appear! Note that each string of lights is created as its own unique group.
Note: It is OK that some of the lines are going through the “Groove Coffee” sign, because the string light plugin creates a catenary curve that will sag realistically below the sign.
4 - Try creating some more string lights by using the other pre-made helper line and/or creating some of your own helper lines. Play around with the plugin’s settings to get different results.
5 - To help keep the model organized, when finished we recommend grouping all the helper lines and placing that group on the Helper Geometry layer, as well as assigning all string light groups to the Context – Exterior Lighting layer. This will prevent the helper lines from showing up in any of the ‘Eye Level’ scenes where we do not want to see them. When finished, the results should look something like the next screenshot.
Note: Unlike geometry created from a Dynamo script, which can be updated and regenerated through the Properties Palette, objects created by a plugin are (for the most part) just regular FormIt geometry. Once created, they can only be edited using FormIt’s built in modeling tools.
