When creating road styles in InfraWorks, everything to the right side of the median (i.e. the roadway, curb, sidewalk, greenspace, bikepath, etc.) is organized into a "Right Group". By default, the left side of a roadway in InfraWorks is a mirror copy of the "Right Group" in that road style.
To tweak this a bit, you can add a Left Group to a road style and create customized road features, such as staggered street lighting. (On a separate topic, users of Roadway Design for InfraWorks 360 can also use style zones to modify road styles).
Staggered street lighting
To begin, open the Style Palette, select the Road tab, and select a road style that you want to edit. In this example, I created a copy of the Street/Sidewalks and Greenspace road style. Select the copied style (give the copied style a new name if you'd like), and click the pencil icon to edit it.
The Left Group will appear automatically.
You now have to create copies of all the tracks (in this example, the Roadway, Curb, Sidewalk, Greenspace tracks) within the Right Group, and place those copies into the Left Group.
You may initially notice that the Left Group (everything left of the road median) looks totally wonky. That’s because InfraWorks arranges the order of the road track components according to how they are arranged in the Track Settings section of the "Configure..." dialog box.
Simply switch the order of the components to fix this.
Now that you have a properly configured Left Group, click the Decorations icon and add decorations to the Right Group. In the Decorations Editor, make sure you are selecting the appropriate Decoration Target, then click to add a decoration.
For this example, I selected the 3D Model/City Furniture style catalog, and chose the "Street Light w_1 Bulb" 3D model, then pressed OK.
This added the street lights to the Right Group sidewalk.
Repeating this procedure for the Left Group adds streetlights to the Left Group sidewalk.
Now, to stagger the alignment of the street lights, I increased the spacing for both the Right Group and Left Group street lights from 10.0m to 20.0m. I then added a spacing offset of 10.0m to only the Left Group.
If you look closely at the style preview, you'll notice that the street lights extend past the border of the sidewalks and intrude into the greenspace.
If you want to change this, adjust the track offset for the street lights in both the Right and Left Groups. I added a track offset of 0.25 m, which seemed to work nicely.
Click Close, and then click OK to finish creating the new style with staggered street lighting.
And remember-- you can add any 3D object to a road style as a decoration if you first import the desired 3D objects into the appropriate style catalog (for help with this, see the To Import a 3D Model into a Style Catalog Help topic).
