FF/polynet/!PolyNet/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!PolyNet
last updated 30 June 1997
The PolyNet application draws a view of a polyhedron as
a 3D solid and helps you to create a planar net for it.
There may be many possible nets; if you want to print the
net, cut it out and recreate the 3D polyhedron, make the
smallest number of tabs to cut out and stick together.
Click on !PolyNet to load it on to the icon bar.
Turn on !Help (in Apps) for continuous help over windows.
Drop the data file for the polyhedron on to the !Polynet
icon on the iconbar, to open a window showing the solid
drawn in white with faces outlined in black. The name of the
polyhedron is shown in the title of the window.
If the solid already has some 'net' data you will see a
warning window, Click on the 'OK' to continue, or 'Cancel'
to ignore these old net data.
*** Warning ***
Some old net data do not conform properly to
the face ordering conventions expected. This may produce
curious effects on the tabs if you try to delete faces
from the net.
Click 'MENU' over the icon on the icon bar for a menu
where you can read the latest version of the program
by looking at 'info', display this help, change the choices
(face colours and tab shapes and colour) or quit.
How to make the net
(The description assumes that the default face colours
set in the choices file have not been changed.)
Click 'SELECT' over any face of the solid, which will
turn red to show it is the last face you selected. A new
'net' window opens with the face you selected rotated
into the plane of the screen and coloured red.
Click on an adjacent face in the solid to add it to the
net. The previous face turns grey in both windows to show
it has already been selected. The net window always shows
the part of the solid you are working on in the middle of
the window. Then click on another adjacent face, to add
it to the net. If all adjacent faces are coloured, you
can click 'SELECT' on a grey face already selected in
another part of the solid, to turn it green in both
windows. You can then continue from this face until
the net is complete. You can only select faces which
are adjacent to the red or green ones, clicking over
others makes the program 'Beep'.
Rotating the solid
When you have clicked on all the visible faces in the 'solid'
window, use the cursor keys to rotate it so that you can see
more faces to select. The arrowed Cursor keys, and the
'Page up' and 'Page down' rotate the solid; < and > change
its size, when the top bar of the 3D window is coloured yellow.
Click 'SELECT' anywhere inside the window to turn the top
bar yellow when it is grey.
Click 'ADJUST' over any face to remove it from the net; if
you pick one other than the red face it is quite likely to
make a hole in the net which may be hard to repair.
Saving the net
When all the solid has been made into a net, a small menu
appears with two items. Choose 'data' to save the data
for the solid as it was read in but now with the additional
net. Choose 'draw' to save the net as a Draw file. Save the
files in the usual way by dragging the sprite to the
directory where you want to store the new file.
You can save an incomplete net as a Draw file at any time
by clicking 'MENU' over the net window, and then clicking
on the 'OK' icon in the following warning message window.
Incomplete nets have no tabs.
Note that it is not possible to make a single net for
some of the non convex polyhedra. Some of the larger ones
may be 'floppy' and need internal strengthening planes;
!PolyNet makes no attempt to draw such planes.
Some stellations are easier to make if you start from the
original polyhedron; for example, make the 3D model for
the dodecahedron and then to make the 1st stellation,
use !PolyNet to make a net for one pentagonal pyramid,
use !Draw to replicate it 11 times, and stick a pyramid
on to each face of the dodecahedron.
You can erase all the faces so far selected by clicking
'Menu' over the solid window and choosing 'restart'.
Choices
Click 'MENU' over the icon on the icon bar to see a window
where you can change the default colours of the faces,
request tabs be added to the Draw file and change the
parameters affecting their shape. You cannot save your
new choices if the 'save' icon is greyed out. This happens
when the access to the 'Choices' file is locked, as it may
be when running on a network.
Default colours
The colours are chosen from those of the Acorn Desktop.
Face colour index
Unused face white 0
Used face grey 2
Last selected face red 11
Selected face green 10
(when a previously selected face is chosen as the next
one to add another face adjacent to it)
Change the colours by dragging the icon of the new colour
from the column of possible colours on the left on to
the icon adjacent to the item to change.
Tabs
The 'Show tabs' icon is selected by default.
Tabs are filled with colour cream, number 12.
The angle which the tab makes with the face has a default
value of 60, a maximum of 99 and a minimum of 1 degree
The width is a fraction of the length of the side of the
face to which it is attached. The default value is 0.25,
the minimum 0.1 and the maximum 0.6. To change any of these
select 'Choices' from the MENU of the icon on the iconbar.
Further information can be found in the directory 'Docs'
including a definition of the file formats.
If you find an error, please copy the file 'Docs.FaultRep'
to another one, named for example 'EReport', and use an
editor to complete the form to tell us what you were doing
when the error happened. Send the report to us at the
address below, preferably with an example data file.
The more details you can give us the more likely it is
that we will be able to reproduce your problem and correct
the program.
