'BASE Command

Sets the insertion base point for the current drawing

Draw menu: Block > Base
Command line: base

Base point <current>: Specify a point or press ENTER


Use BASE if the current drawing is to be inserted into or externally referenced by other drawings and needs a base point other than 0,0,0.

When you insert or externally reference the current drawing in other drawings, AutoCAD LT uses this base point as the insertion base point.

Related Commands: INSERT inserts a drawing into the current drawing. BLOCK creates a block definition from selected objects and sets a base point. XREF links a drawing to the current drawing by creating an external reference to the other drawing.
System Variables: INSBASE stores the insertion base point.
