It is easily replicated and is definitely a Mac only thing, as only a Mac
has a separate menu bar at the top of the screen shared by multiple windows.

Basically whilst distracted by my partner I hit the Quit Openscad from the
Menu Bar instead of using the close button on the title bar of the second
OpenSCAD window, .

Instantly closing all open windows is consistent with other MAC
applications.

Not checking for unsaved changes when Quit’ing seems to be the default in
OpenSCAD even for a single window with changes in it.

However most Mac applications such as Mail, will on Quit Mail save the
contents of all open windows (e.g. the 'Compose new Message” window that I
am currently using to type this note in. It will then recreate this second
window when the application is restarted.

Similarly the Brave Browser will on Quit Brave remember the open tabs and
reload them but it will not do so when it has been closed via the close
button.

So there is a case to argue that Mac needs the extra save check function
as it is possible to Quit and loose all of your design changes - but this
is totally unique to the Mac interface and it looks like I am the only one
to have fallen foul of it to date and admit to my stupidity - so I would
not put a high priority on it.

It could also be a Mac thing. I don't think my original 128K Mac will run
OpenSCAD, so I can't test.

Not on Mac - there is the “*” in the file title - the problem arose
because I opened the second file from finder which opens it in a separate
window and not in a tab - so I had two windows open and not two tabs.

I went to OpenScad-> Quit Openscad on the active window which had no
changes expecting it to quit that window and it quit both windows
simultaneously without a save prompt for all of the changed data in the
other window….

I was not able to reproduce the quit without saving behavior with OpenSCAD
version 2021.01, and macOS 12.1, when in the Mac's System Preferences >
General* [] Ask to keep changes when closing documents* was not checked, []
Close windows when quitting an app was also not checked.

I opened the OpenSCAD app, and typed sphere(d=60); into the editor. Then
I opened a new window, then hit Quit from the menu bar. I got the
expected alert saying:

• Some tabs have unsaved changes.*

Do you want to save all your changes?

(Don't Save) (Cancel) (Save All)

This is what I'd expect a Macintosh app to do. Almost. The alert seems to
think I have multiple tabs open when in fact I have multiple windows open.

If I hit (Cancel) the quit action is canceled. If I hit Don't Save then
it doesn't save and the quit action completes.

It looks like you told it not to save, then complained when it did what
you told it to do.

Odd,
I replicated it multiple times just to find out what I did before asking
for help.

OpenSCAD version 2022.01.14 (git e6894b77a)
MacOS Big Sur 11.6.2

We do however have slightly different preferences set - though as far as I
know these are the system defaults as I had not heard of them before your
response and I can not recall ever changing them.

[] Ask to keep changes when closing documents was not checked
[] Close windows when quitting an app was checked

I unchecked both, and the quit still does not offer a save prompt but I am
now seeing save files in Documents/OpenSCAD/backups for the first time
since I installed 11.2.3

thanks Bob C.

Ok, so I don't want to try to decipher the Round-Anything code, but if
you take a look at extrudePolygonWithRadius, it returns a list whose
first entry is finalPOlyhedronPoints.  If you take the max x value of
points in this list, that will give you the information you want for
positioning the hole.  In BOSL2 you can get the point list for almost
any object.  (Some earlier code may be written to not return it.)  So
you can very easily do this if you want.  But the actual way to do
things in BOSL2 is to use attachments.  So you ask how to make a hole
5mm from the right edge.  You tell BOSL2 to put a hole 5mm from the
edge, like this:

use <Round-Anything/polyround.scad>

include<BOSL2/std.scad>
include<BOSL2/rounding.scad>

module bh()
{
radiiPoints=[[-4,8,0],[12,8,20],[23,15,13],
[55,0,13],[23,-15,5],[12,-8,20],[-4,-8,0]];
radii = [for(x=radiiPoints) x[2]];
pts = getpoints(radiiPoints);
rounded = round_corners(pts, radius=radii,$fs=1,$fa=2);
diff("hole")
offset_sweep(rounded, top=os_circle(r=3), bottom=os_circle(r=3))
tags("hole")
left(5)position(RIGHT)cylinder(r=2, h=20,anchor=RIGHT);
}

bh();

For the gears, it sounds like you want to do something with the bottom
and top faces of the gear.  It looks like possibly there's a bug in
the bevel gear attachment positions---I'm not sure.  It appears
there's no way to get the point that is the actual bounding box, the
top of the teeth.  But if you want the top face of the gear or the
bottom:

include <BOSL2/std.scad>
include <BOSL2/gears.scad>

bevel_gear(
pitch=5, teeth=36, face_width=10, shaft_diam=5,
pitch_angle=45, spiral_angle=0 ){
attach("flattop")cube(15);
attach(BOTTOM)cube(15);
}

If you really want to muck around with the numerical values yourself,
it's possible.  This example puts the demo cube at the actual bounding
box top, where the teeth tips are, instead of the top flat.

gear = bevel_gear(
pitch=5, teeth=36, face_width=10,
pitch_angle=45, spiral_angle=0 );  // gear is a VNF structure,
gear[0] is points, gear[1] is faces

bbox = pointlist_bounds(gear[0]);

vnf_polyhedron(gear);
up(bbox[1].z) cube(30);

PolyGear library which I was able to modify to provide bounding box info.

to an object of a known length.  I also temporarily add a cube or cylinder
of the desired length.  I have to do that only occasionally.  For me, this
is only a minor annoyance.

accurate measurement system can be integrated in the interface without
modifying the engine - I actually had to use a physical ruler to measure
the projections on the screen for my last design.

Ha.  For me the massive frustration is Word.  If I am forced to use
Word I know to budget double the time for all the time wasted trying
to get Word to do things that are easy in LaTeX.  Figures won't
renumber correctly.  They'll number out of order.  All sorts of stuff
just doesn't seem to work.  It's so frustrating, and when you get
done, the output looks far inferior to the output produced by LaTeX.
Anytime someone asks me to use word I push back and see if I can
supply a pdf instead so I can stay away from that time sink.

thing and may have been derived through some complex process... and even
the fact that it is a cube may have been derived through a complex
process.

things like re-stack or rearrange the shapes that a "paint" program can't
do... and at the same time they can't easily do things like erase half of a
