SHAPE
Inserts a shape from a shape file that has been loaded using LOAD.
Codes 3 and 4: Size Control
Codes 3 and 4 control the relative size of each vector.
The height specified with the SHAPE command is initially considered the
length of a single orthogonal vector (direction 0, 4, 8, or C). Code 3 divides
vector lengths by the next byte. Code 4 multiplies vector lengths by the next
byte. Codes 3 and 4 are followed by a specification byte containing an integer
scale factor (1 through 255).
If you want the shape height to specify the size of the entire shape, and you
use 10 vector lengths to draw it, you can use 3,10 to scale the height
specification. The scale factor is cumulative within a shape; that is, multiplying
by 2 and again by 6 results in a scale factor of 12. Usually, you should reverse
the effect of your scale factors at the end of the shape, especially for subshapes
and text font shapes. AutoCAD for Mac does not reset the scale factor for you.
Quick Reference
Commands
LOAD
Makes shapes available for use by the SHAPE command.
SHAPE
Inserts a shape from a shape file that has been loaded using LOAD.
Codes 5 and 6: Location Save/Restore
Code 5 pushes (saves) and code 6 pops (restores) the current coordinate
position while drawing a shape so that you can return to it from a later point
in the shape.
You must pop everything you push. The position stack is only four locations
deep. If the stack overflows because of too many pushes or too many missing
pops, the following message is displayed when the shape is drawn.
