hull to connect parts probably won't work due concave surfaces in some places. hmm, but diferenciating to remove redundantly hull-filled insides, probably will result in non uniform wall thickness

it would be nice if we had the ability to deal with surfaces, wouldn't it, and then you would minkowski it
<Virindi>
how about you define the inner space, then minkowski it, and subtract the inner space

Hi,
<Knochi>
I have a challenge for you (and for me) :-)
<Knochi>
So I'm trying to replicate a model in openSCAD with a lot of roundings and such
<Virindi>
do people actually use openscad for sculptures other than math ones? that would surprise me. seems like more of a blender thing
<Church->
Knochi: i don't see much problems in your model. Hardest part to do (rounded join/fillet of various surfaces) is absent in it.
<Knochi>
So any tipps on how to do the detail I highlited in the last picture?
<Knochi>
might have to reload the page.. multiple images there now
<Church->
Rest seems simple to do. For feet, linear_extrude -ed hulled two circles+square. For triangle rounded joints, triangle + circle. For front hatch cone from cylinder with different top & bottom radius. for "sight" and for side windows, sphere that is flattened or prolongatted with scale
<Knochi>
yes did some of this already
<Church->
IF you don't need chamfered/filleted joins of all these figures, it looks simple to replicate
<Knochi>
Virindi I know, but I want to add some electronics later on and 3D print
<Church->
also for round surfaces, when slicing, probably helpful to have variable layer lines, for top of spheres to not have too visible layer lines
<Virindi>
you could always import the original and cut out the inside where you need
<Church->
err, variable layer height
<Knochi>
Church- not all but some... so that thing on the bottom right of the front ring. that looks like a handle of washing machine..
<Knochi>
Virindi but where is the challenge than? :-)
<Virindi>
ah okay :)
<Knochi>
And I want to split it up to print in different colors and assemble later
<Church->
Knochi: that handle/hinge still, looks to me as (low height) cone (from cylinder), from which you cut sector, and minkowski for front chamfer.

<Knochi>
hmm that might be a path
<Knochi>
the thing is, it doesn't have any flat face
<Knochi>
but yeah.. cylinder.. cone... hull and a rotate extrude may do the trick
<Church->
rounded edge of side-windows from moved to side and cut with cylinder sphere, might be got with circle rotate_extrude -ed.
<Knochi>
ah these ones i did already
<Knochi>

Virindi: sorry, forgot to thank you for your help in my case :)

I chose a rotate_extrude + poly for the body
<teepee>
mohammad1722: congratulations, there's a bit of time till the official project start, the time till then is supposed to cover a bit of more introduction and planning
Guest89 has quit [Client Quit]
<teepee>
so maybe we can use the time for discussing where you will start and also what might be useful on the OpenSCAD side to support so maybe we can get some changes on that side too in parallel
<teepee>
I have to go for now...
<Knochi>
me too.. thanks

teepee: Ok then, I'll be setting up my environment for OpenSCAD and we can start our discussion once you're available.

Hallo
<clrsrc>
Does Anyone has got an idea to solve the following problem with openscad ? I 3D scanned an objekt , a plane surface with a bulge . Now i want to get this bulge as an object ( stl ) to fill it with a 3 D print.
spuz has joined #openscad
<InPhase>
clrsrc: You missed the part of telling us what kind of data you have of it.
<clrsrc>
the scanned object is in format .stl
<InPhase>
So then it is already an stl, which is the end goal?
<clrsrc>
from this scanned object i want create a stl , which has got exactly the dimensions of the bulge
<clrsrc>
finally to repair / fill the bulge with the printed bulge

anti aliasing would be to turn the fringe pixel on at 20% or so .. you just blur/diffuse the pixel which can't be turned of so easy .. imagine a servo moving the pixels away Ü
<teepee>
yeah, it was actually just blurring, this was more turning the comment by InPhase around than trying to be technically correct
<teepee>
in totally unrelated news, the MMU3 is now in house :)
