Importing Layers

Importing Layers

As previously illustrated, a 2D block imported from AutoCAD is easily replaced with a 3D component version in SketchUp. If the site elements were organized on layers, these layers will import into SketchUp. Replacing the block with a component does not remove the object from the layer. For example, editing the single, tree block/component with a 3D version will place trees wherever that component is present. The 3D versions will still be on the tree layer.

Furthermore, the Tree layer can be toggled on or off to hide or make the tree visible; the layer structure will be preserved (Fig. 19-6).

Fig. 19-6: The AutoCAD layer structure stays intact. Each component type is on its own layer, just as in AutoCAD.
