The pen tool includes the following functions: drawing soft line, hidden line, auxiliary line, welding line, edge line, common line and auxiliary point.

Divides the faces assigned to the material by the side length.

The quadrilateral surface, circular surface and special-shaped surface are divided, and the original topological structure is still maintained.

This command can quickly align the selected objects on the red, green, and blue axes. Object objects support groups, components, faces, and borders.

SketchUp's own undo history can be saved more than 100 times (not tested specifically), but it does not have a history panel like Photoshop. If you want to restore to an earlier state, you can only press Ctrl + Z all the way back. This function can choose undo or redo freely

The planar 2D curve is extruded along the Z axis and converted into a spatial 3D curve.

This command can divide the selected rectangular face randomly according to the scale, and can copy, randomly push and pull and invert the selected face offset.

You can bend the group by the selected curve path.

Mark, select, delete, or display line stubs for all open segments in the drawing. Can be used to check and organize imported CAD drawings.

Select three or more closed sidelines, input the mesh division value, the controllable surface will be generated dynamically, and its tension ratio and tension value can be edited and adjusted subsequently to correct the surface.
