Tool Name: Extrude
Author: Adspec Programming
Last Revision: Dec 17, 1993;
______________________________________________________________
PURPOSE: To Extrude selected polys.
______________________________________________________________
RESTRICTIONS:
Does not operate on splines.
No textures or shading can be copied.
______________________________________________________________
USE:
This tool can be used with either a LEFT MOUSE BUTTON
which uses the stored defaults or with the RIGHT MOUSE BUTTON
to change the defaults before use.
______________________________________________________________
TO CHANGE DEFAULTS:
1: Click the RIGHT MOUSE BUTTON on the tool's gadget.
2: Edit the offset gadgets to the desired values. The values are
in units in space and are the amount in the x, y, z axes that
the extrude will occur.
3: Set the other options as desired:
FINAL %XYZ: The final percent (100 is unity) allows you to
reduce or enlarge the selected polys along the extrusion.
SEGMENTS: The number of segments to be created. Cannot be 0.
LAST POLY: If ON, the last segment in the selected polys will
participate in the extrude. If OFF, it will not.
SWELL: If a Power is set to a non-zero value, a power function
is applied to the extrude. This gadget allows you to distribute
the power function either from the selected polys, or away from
the selected polys.
DEL CON: If ON, after the extrude is performed, all new polys will
be examined and if any are in exactly the same space, they will be
deemed to be interior to the extrude and will be removed.
THIS IS VERY IMPORTANT FOR FONTS and other polygons that have
"holes" created in the polygons with "bridge" segments between the
exterior part of the polygon and the interior "hole", like a
letter "O". If you extrude a letter "O" with the DelCon OFF, you
will get 2 extra polys at this "bridge" which can cause havoc with
shading assigns.
In general use, leave this gadget ON.
POWER: the value of the power used in the swell. Leave 0 if no
swell is to occur.
POLY TO POLY: If this is ON, the program will look through all
polys in the current space and determine that you have exactly 2
polys selected. If this is true, it will count the points of both
polys to insure they are the same. If this is true, it will build
a shell between the two polys on a point by point bases starting
with the first points. This allows you to create "cross sections" of
objects, then "skin" them.
SINGLEGROUPS: This option is designed to work hand in hand with
the ALIGN tool. If ON, the program will automatically group EACH
selected poly and its extruded shell and end poly in a single
group IN GROUP LEVEL 3 only. This facilitates use of extruded
fonts with the align tool. See the align tool help file for more
information. NOTE that any old group information in group level
3 will be replaced with the new groups.
If you select the PERFORM gadget, any selected polys will be extruded
using these defaults. If you select the ACCEPT gadget, the new defaults
will be saved for future use. If you select the CANCEL gadget,
the window closes with no changes saved.
______________________________________________________________
FOR USE WITH STORED DEFAULTS:
1: Select any polys you wish to extrude.
2: Click the LEFT MOUSE BUTTON on the tool.
After a few moments, you will see the extrude appear at the
currently set default offsets. Note that with many polys selected,
this can take some time.
NOTE that the original polys are deselected, so you can, if desired,
immediately hit the deletepoly gadget to delete the extrusion
leaving the original polys untouched. Be sure any objects that
don't participate in extrusions, like splines are not also selected
because they may not be deselected and will be deleted!
______________________________________________________________
OTHER:
If the extruded polys are assigned to paths, the new polys will be
assigned to the same path unless the path uses deforms.
