                     How to use 3DSolids
 3DSolids is an ABasiC program located on this disk. It may 
 seem a little  difficult to use  for those of us  that are
 not familiar with three dimensional rotating graphics, and
 this is not a tutorial  on that subject,  it is just a few
 examples  keystoke by  keystroke that  I tried that worked
 fairly  well. After  you have  loaded this  program in (by 
 clicking on  the ABasic Icon to  bring up  Basic) and then
 typing (at the OK  prompt)   run 3dsolids   you will get a
 screen of text.  After you have read this screen press the
 RETURN key once and you will be asked:

 (D)isk file or (K)eyboard input? (D or K)
 you should answer by pressing --- D (NO return is required)
                     
 For Disk Directory, Input (DF0:), (DF1:) or (N)one?
 your answer is --- N <RETURN>
 
 Enter Drive: Filename to load. (DF_:Filename)?
 if the disk is in the internal drive type:
 DF0:Columbia.3D <RETURN>
 if the disk is in the external drive type:
 DF1:Columbia.3D <RETURN>
 After a few moments you will get a message and a prompt.
 
 ENTER OBSERVER LOCATION (X,Y,Z) : ?
 you should then type:
 500,90,90 <RETURN>

 ENTER COORDINATES LOOKED AT X,Y,Z
 you type:
 10,10,10 <RETURN>
 
 DO YOU WANT TO DO AN X,Y LOOP?
 it is asking if you would like the shuttle to rotate!
 your answer should be Y for yes

 HOW MANY DEGREES TOTAL ROTATION ?
 your answer is 90 <RETURN>

 HOW MANY DEGREES ROTATION PER FRAME ?
 answer is  10 <RETURN>

 At this point the screen should change  color and in a few
 moments the  shuttle  should appear  and after  a few more 
 seconds the screen will re-position and the shuttle should 
 have moved  10 degrees, this  will  happen  9 times  for a
 a total of 90 degrees.
