PurgeEach time a component is modeled, that component is saved by SketchUp inside
file. Even if it is deleted, it is saved in a library for the user to recall
whenever required. Though this is very helpful, yet it makes the file size
extremely large, especially when components are imported from the online 3D
warehouse. It is necessary that users visit Window>Model
Info>Statistics>Purge Unused, periodically and watch their component count
and file size decrease and feel SketchUp running faster.
LayersUsers must put detail items that they do not require to see all the time on
their own layer. This will help them to toggle these items off while they are
working on their broader modeling strokes. It is important to be careful while
using this one. Ii is recommended that users should model everything on their
Layer0 and group up similar items using the outliner tool and manually change
items from layer0 to their desired layer using the entity information tool bar
i.e. Window>Entity Info.
Hidden GeometryUsers can toggle to View>Hidden Geometry on and check if there are any
hidden geometries they need to remove. Hidden geometry will show up with a
crosshatch infill and removing these hidden geometries definitely speeds up
SketchUp.
Last Save with Minimal in ViewTo ensure that the files open quickly, users should make their last save
count. They should make sure that shadows are disabled and any extraneous layers
are toggled off.Ref : http://designerhacks.com/speedupsketchup
