teepee just thought if lazy U causes 3mf to have separate objects - this is i problem as the speed advantage is gone cuz you need one group of objects. Meaning they can be multiple meshes (which is great) but need to be grouped for the export - else you get problems with the slicer ( or have to merge them )

J22: yes, lazy union (other than most other experimental features) is not even finished in it's current state
<J22>
3mf supports also grouped multiple meshes ( you can ungroup them in the slicer if needed )
<teepee>
yes, I think that's what the spec calls "constellations"?
arebil has joined #openscad
<J22>
sounds celestial .. if so this is much better than "separate shells" as this can't work with adjacent objects as they are likely in multi material prints

teepee just got an idea for your signal tower - a nice light Diffusor could be made from clear plastic that is spiral printed as filter - as each string has nice optical properties and act as a linear lens, so refraction rise luminosity here an example for a filter https://www.prusaprinters.org/prints/125053

@teepee, oh, I see. I knew I was missing something but thought I would contribute just in case.
<nelson_>
Changing the subject slightly, I made a curved molding for my kitchen. It has the same profile as the 8' long strips of poly molding from Lowes, but I rotate_extrude'd it with a very tight curve -- far tighter than you could bend it. https://photos.app.goo.gl/snDGZwoLHtsFDsTu5
<nelson_>
teepee, Yes, my design should scale down to fit that. Here it is installed on a two-signal mast: https://photos.app.goo.gl/iXT6fscdMZTz39Vn8 You can't see the diverging track because the signal blocks it.
<nelson_>
The Park Railway is 15", about twice the size of the railway I designed the signal for.

any idea why it renders 30minutes only to state "no top level geometry" which is clearly there when rendering only parts or in preview
<teepee>
that can happen when mixing 2d and 3d
<teepee>
preview does not care about that
<J22>
but didn't that give you a "mix 2D 3D warning"
<Scopeuk>
J22 if you are willing/able to share your scad code people might be able to be more specific
<J22>
not sure what happens but it works with one value and slight change ends like that ..
<J22>
Scopeuk you know my code .. and there is a lib involved as i said A renders fine B renders fine A+B " no top level" .. now flushing cache 20GB .. hmm there are gaps in the memory graph .. odd
<J22>
maybe rendering two projects at the same time wasn't so clever
Guest3782 has joined #openscad
<J22>
peaking 45GB and i only have 32GB
<Scopeuk>
so your top level file is ...include libraries... libAPart(); libBPart();? or similar
Guest3782 has quit [Client Quit]
<Scopeuk>
that's a huge memory usage
<J22>
limit is 44 and it peaked at 49 so maybe that caused it

wow, what size are those images, that takes ages to load :)
<teepee>
I hope that's not telekom reverting my network to modem speed
<teepee>
whew, nope, 52.98 Mbps, pretty much exactly what the contract said
<J22>
loads ok here
<J22>
its i bit funny they made the gear that big as it is not taking any load
<teepee>
that last one with the hand in picture is somehow broken
<J22>
not here .. all images .. maybe reload the whole page
<InPhase>
Loads pretty fast here. Have you tried using your gigabit Internet connection?
<InPhase>
(I jest. One thing my employer gets very right is the bandwidth available on campus.)
<teepee>
the internet is fine, not gigabit but 1080p YT plays happily on the other monitor
<teepee>
maybe firefox does not like those webp files

Hmm. Looks like my home internet provider FiOS's lowest advertised speed is now 300 Mbps. When I get home I'll have to run a speed test and see if they upgraded me, or if they're charging me the 300Mbps rate and still giving me the old 100Mbps speed I initially signed up for.
<InPhase>
I opted not to pay more because it was hard to find a use case where the difference mattered. But if that's the base rate, that's what I should be getting now.
<teepee>
I'm fine with my 50Mbps, supposedly they support 200 here but that's probably just theoretical
<InPhase>
I suppose my larger downloads have seemed unusually fast in recent months. That might explain things...
<teepee>

Question: procedural textures in openscad.
<lf94>
Why is it not there
<lf94>
Or even shaders

strange question... because features do not magically appear, only when someone does the work

also shaders do exist
