This function is a set of parameterized geometric modeling tools, which can dynamically and interactively operate and edit geometric deformation through setting panel. The resulting parametric geometry object can be edited and modified multiple times.
It includes 15 utilities, which are used to make 2D graphics. Although those tools are similar to those of SketchUp, you don't have to worry about the lines you draw running into 3D space. Your drawing area is only limited to XY plane. 2D tools already includes basic plane processors
