Subdivision is a common method to deal with geometric modeling in modeling. Starting from the initial control grid, according to some rules, recursively generate new points to gradually encrypt the control grid. With the subdivision going on, the control mesh is polished gradually, and finally the smooth curves or surfaces interpolated or approximated by discrete points are generated. ...

You can ignore the influence of the group, select the surface directly according to the material, and hide other unselected objects without destroying the organizational structure in the model.Note: you can't choose the opposite material!

Infer that the material plug-in function can be randomly assigned to other surfaces without materials according to the assigned material surfaces in the selection area, and the allocation proportion of materials does not change.

You can select materials to replace, absorb new materials for replacement, ignore the group level influence, and expand the operation of the default material manager.

The clean up model plug-in is a complete set of tools for cleaning up SketchUp models, which can be optimized for global or selected models, clean up unused items, hide entities and duplicate faces. In addition, you can also merge the merged layers into layer 0, merge the same materials, ignore normal, material or UV merge coplanar, repair
