Fredo tools is a collection of a series of small plug-ins developed by the author Fredo 6. It contains many practical tools, and there are many kinds of line and surface tools.It includes angle checking, automatic flipping, construction surface reference normal, convex hull decomposition, statistical surface type, curve ramp, bisector, inferential drawing

Intelligent chamfer plug-in chamfers and reverses the edges along the corners of the model. There are several modes: fillet, straight edge, bevel and subdivision mesh. In addition, it includes a repair tool to undo any generated shape.Compared with round corner, intelligent chamfer can deal with more complex shapes and advance at vertices

Parametric animation is a plug-in dedicated to SketchUp model animation. It provides an interactive adjustable parameter framework to control the position movement of the object model and the camera along the time axis.In the process of using, the parameter animation plug-in will record the motion track of the model and camera as parameters, and we can modify it at any time

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
