You are right
I will post the code.

As an side -- generally, it isn't useful to check computer-generated data
files into git. It's equivalent to checking assembler or object files into
git. It bloats a repo while serving no purpose since they don't need
version control. Instead, provide a Makefile or script that generates the
output files on demand. Check in only the source code (in this case the
Python) and the script.

Hi Gene,
It's really wonderful to see your passion especially at your age.
I would say you are 90 years young.
My father would be 90 if he was around and frankly speaking he was a great
inspiration to me and I miss him a lot.
Thanks for your message and all the best for your 3d modeling journey.
Regards
Sanjeev

I know it's quite complex for anyone to understand.
I have hard time explaining concepts maybe due to my not so great
English skills. Explaining through pictures and videos take a long time.
Never mind
Don't apologize for your English skills Sanjeev, they are better than
mine. But you likely have quite a few more years learning it than I. I
quit school shortly after the first 8 grades, and went to work fixing
the new fangled things called a tv's, in 1948. Eventually switched to
broadcasting, I kept a series of tv stations on the air from '63, to the
middle of 2002 as the CE & often the only tech in the building. I enjoy
someone else thinking outside that famous box they try to put us in. So
please do continue.
OpenSCAD, FWIW, has leaks. What it has taught me about a list of
polygons was leaked over into linuxcnc which I also have used for the
last 25+ years since before I retired. Thank you /all/ for the
inspiration and the ability to be productive as I approach my 90th.
Pretty good for a now old & diabetic Iowa farm kid.

I personally like seeing what Sanjeev does with his hybrid process.
I, too, have used Python to generate OpenSCAD code (see the attached
tensegrity tower). However, I do admit that his programming is
complex and difficult to follow in his videos. Someday, when I have
more time, I'll delve deeper into his techniques and see what I can
learn.

I am writing mostly python codes which generate polyhedron in

Apart from that I use difference(), union() , hull(),

If you don't like the python codes, please ignore my postings as
most of them are python codes.
In case the majority here feel distracted, I may decide not to
post any further.
I am just trying to convince the developers that python can help
improve openscad.
Guenther has written a good python-scad software, but somehow it
needs further work.

Sanjeev:
It would really help me if you distinguished between
OpenSCAD code (real code, not just coordinates) and python
code. That way I will know what I want to pursue and what I
want to ignore.
Thanks.

I really do think outside the box. For instance, the last 4 years has
seen a slow revolution in stepper motor tech. And I have a now elderly
Creality Ender5plus 3d printer. Big and relatively cheap. Its achilles
heel is the motor driving its Y axis, loses steps, aka a layer shift at
20mm/sec speeds. 24 volts runs everything. I rebuilt it from frame up.
Carbon fiber X transport to reduce flying weight, stepper/servo XY
motors, 72 volt supply to run them, 32 volt 600 watt psu for bed heat.
Stepper/servo's control the motor much more precisely on less power. A
new hotend goes to 280C. The whole thing now runs at up to 175mm/sec, no
layer shifts, printing stuff in polycarbonate, 60C hotter bed, 100C
hotter nozzle. Now the problem is the author of klipper. The
stepper/servo, when used with linuxcnc, can hit something on the machine
and stop the machine in 2 milliseconds. Remove the wrench blocking
motion, remove the cutting tool, rehome the machine, replace the cutter
and tap R on the keyboard, part is not ruined. Klipper needs a similar
instant stop but Kevin isn't willing to add it. The stepper/servo makes
the motor do exactly what the stepgen tells it to do, reversing the
motor to reposition it correctly on a single step of overshoot. I'm
using 5 of those motors on linuxcnc machines in the garage, 2 driving
rotary axises im time with much slower x or y motions to cut threads at
up to 500 rpms. They don't normally make mistakes.
Why did I do that? To advance the state of the art. Somebody needs to.
If nobody pushes it doesn't get done. Probably the same as your mixing
of OpenSCAD and Python. ;o)
