SketchUp surface drawing tool can draw basic figures on surface easily.

SketchUp scale enhancement tool, intelligent recognition of deformation box, free scaling through control points.

SketchUp bevel enhancement tool, which can directly bevel the boundaries of 3D objects.

SketchUp sandbox enhancement tool can preprocess and optimize contour, edit elevation, preview and generate 3D terrain with neat UV mesh and accurate boundary.

SketchUp interleaving enhancement tool, which uses a user-defined template to make double-sided holes, rubbings, inlays, reliefs and other operations on the shape model, can identify the surface normals to make holes, and can be independently grouped.

Curviloft, developed by Fredo 6, is widely used as a plug-in for surface generation. Curve lofting can preview and edit the generated results, including three lofting commands: select space curve or loft section for curve lofting to automatically generate surface; according to the path and the section on the path

CLF onscreen display: when the plug-in is turned on, when the mouse is clicked, the upper left corner of the screen will display the information about the elements, cursor position, coordinate position and other relevant information of the object clicked by the mouse. The status bar at the lower left corner will display the location in real time according to the mouse moving position. If the mouse moves to the face

CLF normal map maker bakes the normal map of the model with high details through mapping, pastes it on the normal map channel of the low-end model, and makes it have the rendering effect of normal map.This plug-in converts the model to a normal map, which can be used for third-party renderers after export. ...

CLF color by Z automatically assigns the color of the terrain surface according to the elevation and makes gradient transition processing. You can customize the RGB values of the highest point and the lowest point. This plug-in is a terrain analysis artifact, which can make the situation of the terrain clear at a glance. ...

CLF color by slope automatically assigns the color of the slope according to the slope of the surface. By default, the steeper the slope, the brighter the color, and the slower the slope, the grayer the color. You can customize the color displayed by different slopes, which is very convenient for auxiliary terrain and scheme analysis. ...
