Inserts are instances of objects that are actually on the terrain.
Each insert may be altered from the default object in terms of scale, but if the object is altered all the inserts will update to reflect the changes.
The Project Tree in the main editor contains a list of inserts. The list of inserts is hierarchical and each insert may have one parent insert. Also, inserts may be organised into convenient groups. Child inserts are then the responsibility of their parents when it comes to editing them.
Inserts can be fixed to the terrain, which means as the terrain is altered the object maintains its position relative to the ground. Inserts can be made invisible or visible.
Inserts can have user data associated with them. This is useful when exporting the project to another environment as data may be held against each insert. The default entries may stem from a user data template specified in its owning object properties. This is for convenience only as extra information per insert may also be stored.
When running any of the object tools, inserts can be selected at any time by clicking on them. If the mouse button is clicked and held and then the mouse is dragged, this will create a rectangle that will select all objects within this area. To select multiple inserts, hold the control key down while selecting and this will add to the current selection. To unselect one insert from the current selection, hold down the control key and click on the object you wish to remove from current object selection. Alternatively, the user may right-click on object in the project tree in the main editor and choose toggle selection.
