Vector direction codes
All the vectors in the preceding figure were drawn with the same length
specification. Diagonal vectors stretch to match the X or Y displacement of
the closest orthogonal vector. This is similar to the action of the snap grid in
AutoCAD for Mac.
The following example constructs a shape named DBOX with an arbitrarily
assigned shape number of 230.
*230,6,DBOX
014,010,01C,018,012,0
The preceding sequence of specification bytes defines a box one unit high
byone unit wide, with a diagonal line running from the lower left to the upper
right. After saving the file as dbox.shp, use the COMPILE command to generate
the dbox.shx file. Use the LOAD command to load the shape file containing
this definition, and then use the SHAPE command as follows:
Command: shape
Enter shape name or [?]: dbox
Specify insertion point: 1,1
Specify height <current>: 2
Specify rotation angle <current>: 0
The resulting shape is shown in the following illustration.
