This Cinema 4D Plugin allows you to create non-destructive thickness for your spline objects. It works similar like the Cloth Surface on Polygons and covers the same functionality of the Cinema 4D Create Outline Tool.
It works well when you want to duplicate structures for complex appearance.
How to install it
Unzip it and copy the folder "Spline Outline" to the plugin directory of Cinema 4D. If you are using Cinema 4D R19, paste the plugin in the plugins folder of your Cinema 4D application files. If you are using Cinema 4D R20 and above, you can place it in any folder you want and create a path to this folder like shown in the image above. Restart Cinema 4D and access the Plugin from the Plugins (Cinema 4D R19 and R20) or Extensions (Cinema 4D R21 + S22) menu.
Requirements
You will need at least Cinema 4D R19 or newer to use the plugin.
