本插件是关于TT SUbD参数化细分曲面SketchUp插件V2.1.4版，大小：7 MB，支持SketchUp 2019软件，语言：英语。RRCG分享
由thomthom开发的SUbD细分工具，能够根据参数细分物体，配合tt四边面工具使用，操作简洁好用。当mesh面为四边面时，细分的结果会更加精确合理。所以强烈推荐使用thomthom四边面工具来布线
1.使用时首先选择组或组件，然后执行细分命令。
2.可以随时增加或减小平滑程度。
3.也可以随时关闭细分，返回原来的模型编辑布线。

Subdivide quads in SketchUp.Parametric subdivision.Optimized for quad-meshes. Perfect for organic modelling.
Why Work with Quads?
When you have a mesh based on quads it add a lot of benefits. The mesh becomes more regular and predictable. The grid structure that comes from quads provide meshes with directions of flow.
Tools can follow an edge and select loops in a predictable order.
Or they can select every opposite edge, making a ring selection.
UV mapping is also easier – the grid makes the mesh easier to map seamless texture mapping.
Working with Quads in SketchUp
When working with quad based meshes you quickly discover the need for quads where the vertices aren’t coplanar.
In SketchUp this can be a challenge because SketchUp’s Auto-Fold feature will break a quad into two triangles once it’s vertices isn’t coplanar any more.
To allow extensions to work with quads that are not coplanar they need to be able to determine which pair of triangles represent a quad. There is no official standard for this, but the de-facto standard is the QuadFace Tools type of quads.
The definition of a QuadFace Tools quad is that two triangles share an edge which is soft and smooth – with Cast Shadows turned off.
It is highly recommended that you also install QuadFace Tools to assist in creating quad based meshes for subdividing with SUbD. I is a core tool for creating ideal geometry that subdivide well.
Compatibility: Sketchup 2019-2020
