Hi.
I been making a number of small and big AutoLisp applications that I used for
various things designing with AutoCAD.
I made a number of designs, that now is avaible as free-download, but it seems
that a lot of people like to try some of my "in-house" software, and as I havn't
realy followed the changes from ver14 up to AutoCAD 200x , I would be very glad,
if someone could tell me, what the best encrypting program is ; then I can add a
line checking date or existance of some file, making the application stop, so
folks can try some design rutines that _work_ .
The rutines I like to make people try are quite specialised applications, but
recently I had a look around to se what is offered concerning "unrolling"
applications, and in this "niche" I found nothing realy happened and I found my
own rutines being able to handle whatever the other programs I found couldn't
maneage. But it's not just the simple unfilding rutines I like to offer as time
limited version ; designing with unfoldeble surfaces work just perfect with my
3D-Honeycomb method, as if you make a frame structure within develoble surfaces,
you have both the Honeycomb structure _and_ the surface paneling that will fit
_exact_ onto the framework, -------- guess a lot of you know how a modern door
are made ; it is nothing but two thin cheap skins with paper honeycomb structure
glued inbetween. If you ever seen one of these doors, you proberly be surprised
that just thick paper "Honeycomb" can add that much strength to two thin surface
panels, and the 3D-Honeycomb do more than that ; it make you produce an
assembly Honeycomb structure, where you can add a surface outside and inside if
you can just unfold the original surface .
This is why I have started thinking about offering decent unfolding rutines, and
like to know what to do, if you develob applications to work ontop AutoCAD, when
you are stuck with an old version AutoCAD, and want the applications to be used
with latest versions beside develobing the 3D-Honeycomb within 3Ds ?
Here are some links that show the 3D-Honeycomb structure so you know what I
mean;

Also these show what structures I want to show how to cover with an integrated
surface ;

These are just a few, showing the 3D-Honeycomb structure, that can be made with
tradisional 2D manufactoring like Laser cutter or pounching mashines in sheet
material.
Here are a graphic that show what Im'e now "giving away" as free download, at ;

------- you need to sign up as member, but you proberly will like a lot of what
you can se in "files", or "photos" folders.
Still my problem is ; how to make a encrypt that can't be broken like the old
ones we had that could be broken ?
Have a nice day.
