The Bezier Spline plugin created by Fredo6 on SketchUcation.com is a set of tools to create bezier curves easily. As SketchUp does not come with a good option for this, Bezier Spline allows you to create these curves with ease by utilizing the almost 13 tools in the palette.
The most commonly used is the “Classic Bezier Curve” tool, it allows you to place the dependent arc points outside of the arc to control the curve. Also allowing you to place as many points as these as needed. Another useful tool from the palette is the “Polyline Arc Corners” tool, it allows you to create a polyline as you wish continuously and creating a bend which is determined by placing the radius measurement in the dialogue box when first using the tool. There are many more tools that work similarly. Some of the different tools are the “Polyline Dog-Bone Corners” and “Polyline T-Bone Corners” these tools in the palette allow you to place circles in place of corners, these two differ on the place ment of the circle. Some other great features of this plugin is that you can edit curves after you use them with the “Edit” button and it even has a tool to complete curves called “Close Loop Nicely” and “Close Loop With a Line”. This plugin has many features and is best to experiment with them to really understand the full effect of this Plugin.
The plugin has very little drawbacks, but the main thing that this plugin cannot do in our experience is to create curves on all 3 axis’. No matter how much we try the plugin always creates curves on one single plane.
