A BLOCK is a group of objects that have been converted into ONE object. A Symbol, such as a transistor, bathroom fixture, window, screw or tree, is a typical application for the block command. First a BLOCK must be created. Then it can be INSERTED into the drawing. An inserted Block uses less file space than a set of objects copied.
First draw the objects that will be converted into a Block.
For this example a circle and 2 lines are drawn.
Select the BMAKE command using one of the following:
TYPE = B
PULLDOWN = DRAW / BLOCK / MAKE
TOOLBAR =DRAW
