SketchUp 6.0: Purge files

Is there a command for SketchUp equivalent to AutoCADs purge?
Català - Castellano
When working long with SketchUp files, the program keeps in the file memory all the components the we´ve been creating during the process. This might end up on a Huge file that takes very long to open and is slower to handle although the model might be finally not that big.
SketchUp has a command similar to the "purge" command in AutoCAD, but kind of hidden.
The way to find it is to go to "Window - Model Info - Statistics - Purge Unused" This simple. This will purge all the unused components and reduce drastically the file size keeping only the needed information.

AutoCAD: Automatic view rotation with the UCS command

Why does the view rotate automatically when changing the UCS?
Català - Castellano
When turning the UCS or setting a new one, we have the option to just create the UCS or to rotate the view together with the UCS. Some people like it automatic, some like me hate it and prefer to see the UCS rotate but stay with the same view.
The way to toggle between this too options relies on the UC command. If we type UC on the command line, it will pop up a window with the UCS options.

We go to the settings tab and we check or uncheck the box beside "Update view to Plan when UCS is changed". If we keep it unchecked, the view will not update automatically. If we want to align the view to the new UCS we will have to use the "plan" command.

AutoCAD: Adjusting Hatch Density

Sometimes when we want to create a hatch that is too dense we get the following message: "Hatch spacing too dense, or dash size too small." This means that we are trying to create a hatch that is denser than the maximum allowed by the system. This might be changed with a simple procedure. We type the following on the command line bar:(setenv "MaxHatch" "10000"). 10000 is the default value, so it will actually not change anything. If we want to create a hatch and we get the sentence mentioned above, we must increase the maximum density allowed. That means we must type for instance: (setenv "MaxHatch" "10000000"). By changing 10000 for 10000000 we increased the maximum density allowed in the drawing. Try to create the hatch gain, it will work this time. If it doesn´t enter the command again with a higher value till it allows you to create the hatch.

Command line order: (setenv "MaxHatch" "10000000")
