Estimates if a solid operation is possible according to disk free space.

        1. (CHAR) disk name to check (a,b,c,d,e,f, etc.)
     if in geometric module (G):
        2. (Y/N) possibility to execute: y-solid, n-solid & surfaces
        3. (Y/N) solid display: y-wire/hidd./dash, n-no display
if option `y' is selected in prompt 2, depending which display was selected in
prompt 3, the resulting message will be either:
solid is possible, the process will take app. NNNNNNN bytes
or:
solid is NOT possible, you need at least NNNNNNN bytes available
if option `n' is selected in prompt 2, depending which display is selected in
prompt 3, the resulting message will be either:
solid & surf. is possible, the process will take app. NNNNNNN bytes
or:
solid & surf. is NOT possible, you need at least NNNNNNN bytes available
if in solid module (S), there are no other prompts  the system simply checks
the possibility of a surface model and the resulting message will be either:
surfaces is possible, the process will take app. NNNNNNN bytes
or:
surfaces is NOT possible, you need at least NNNNNNN bytes available
If you press <ENTER> after a resulting message, the following message will be
displayed:
you will still have NNNNNNN bytes available on your disk

Description:
This command helps you to estimate the availability of disk space prior to
producing a solid model, or a solid and surfaces model.
Enter the letter of the disk on which you intend to produce your solid model.
If you are in the geometric module, the system asks you if you are creating
a solid model only, or solid and surfaces models. You may create and display
the model in a number of modes: wire frame, hidden lines removal, or hidden
lines displayed as dashed lines (option `y'), or create the model with no
intention of displaying it (option `n'). Each case takes up a different amount
of disk space. In both the case of a solid or solid and surface model, you
must define the type of display you intend for your solid model.
If you are in the solid module, the only estimation you may need is for
producing a surfaces model and the system does not need any parameters.

The system takes into consideration all the components of your model,
including placed objects and all their hierarchies, when doing the estimation
and adds a factor as a safety margin. It then informs you if the operation is
possible or not, and how much disk space will be required for it. If the
message is positive, you are informed of how much disk space will be left
after the required operation.
