Hi Ron,
Here is how I searched for what you are trying to do if I understand you
right.
CLI is the best way to manage software in my experience. I rarely use
GUI utility even in Kubuntu workstation.
As a root in my Kubuntu I have the following aliases:
alias acse='apt-cache search '
alias acsh='apt-cache show '
alias agar='apt-get autoremove'
alias agd='apt-get dist-upgrade'
alias agg='apt-get upgrade '
alias agi='apt-get install '
alias agr='apt-get remove'
alias agu='apt-get update '
alias asv='apt-show-versions -p'

Hello,
I have been using freecad for designing parts, and then milling them on
a sherline mill, getting the hang of that a little bit.
I tried to get used to FreeCAD too but takes more time than I can
dedicate at this point.
I have a lathe too, that works with CNC linux, but noticed heard, that
you can't really make parts, or g-codes, with it for a lathe.
So for program or related library search I do it this way:
* command
acse lathe
That returns more or less related lines with a description like this:
dxf2gcode - prepares drawings of parts for automatic machine tools
php-tcpdf - PHP class for generating PDF files on-the-fly
ruby-ami - Ruby client library for the Asterisk Management Interface
next command will tell me more about some related package:
acsh dxf2gcode
Homepage: https://sourceforge.net/p/dxf2gcode/wiki/Home/
Description-en: prepares drawings of parts for automatic machine tools
This program reads 2D mechanical drawings of parts to be fabricated
and produces G-code tool movement instructions for running on automatic
machine tools (CNC machines) such as milling machines and lathes.
.
This is a graphical CAM (Computer Aided Manufacturing) program.
It accepts input in DXF, PDF, or Postscript format. It supports
milling, drilling, and turning operations, as well as work-holding tabs.
I did not include lines with checksums etc. to make it clearer here.
What wold be a good choice for designing, simple, parts for a lathe,
that will create g-code for it?
"It accepts input in DXF, PDF, or Postscript format. It supports
milling, drilling, and turning operations, as well as work-holding tabs."
That's impressive assuming it work as described.
-----
To install the program I would use the command:
agi dxf2gcode
After that you can execute it from CLI or GUI menu.
Of course there is option to install as a unprivileged user:
sudo apt install dxf2gcode
but I'm trying to save keyboard keys ;-)
thanks,
Ron
I have not tried to install and try this program yet but might do it in
one of my VMs later.
Searching for CAD I received one related app among other things:
solvespace - Parametric 2d/3d CAD
If the output is too long you may narrow it down with
acse cad | grep CAD
here's a description for solvespace:
Homepage: http://solvespace.com
Description-en: Parametric 2d/3d CAD
SolveSpace is a parametric 2d/3d CAD program. Applications include:
.
* modeling 3d parts — draw with extrudes, revolves, and Boolean
(union / difference) operations;
* modeling 2d parts — draw the part as a single section, and export DXF,
PDF, SVG; use 3d assembly to verify fit;
* 3d-printed parts — export the STL or other triangle mesh expected by
most 3d printers;
* preparing CAM data — export 2d vector art for a waterjet machine or
laser cutter; or generate STEP or STL, for import into third-party
CAM software for machining;
* mechanism design — use the constraint solver to simulate planar or
spatial linkages, with pin, ball, or slide joints;
* plane and solid geometry — replace hand-solved trigonometry and
spreadsheets with a live dimensioned drawing.
The best test would be to see how the generated (awful) G-code would
behave in LinuxCNC of course.
This also reminded me about a book I bought in 1990s: The CNC Workbook
(Addison Wesley 65600) that came with a floppy for DOS program. I
misplaced the floppy but remember there was a program to simulate CNC
lathe. Very good book with labs to learn CNC basics.
Good luck,
