dear all,
I started to use the function round3d()... but this ends deadly with my
Lenovo i5, 4cores and 16 GB of RAM.. running on Linux Mint latest.
Is ist the function? Or my code?
F5 takes crazy long for a preview.. Can you recommend an easier way to
round the corners of e.g. a cylinder?
many thanks

module bohrung()
*round3d(or=1.5) *
{
diff()
cylinder(d=25,h=7,center=true)
{
tag ("remove") screw_hole("M6x1.5,35",anchor=CENTER, thread=true);
};
};
The round3d() module uses 3 calls to minkowski and hence is extremely
slow. I've heard minkowski is faster with manifold? I have suggested to
Revar that round3d() be removed from the library because it's not actually
useful in practice, but he disagrees.
To do what you want, use cyl() and use its rounding options.
diff()
cyl(d=25,h=7,rounding=1.5)
{
tag ("remove") screw_hole("M6x1.5,35",anchor=CENTER, thread=true);
};

I tried the original code in the dev version and it finishes preview in 55s
on my machine. But even if you want to wait you have another problem: it
destroys the screw threads:

You can add a bevel to the screw hole, but not a rounding, though if you
use radius 1.5 it doesn't leave much thread on a 7mm hole.
diff()
cyl(d=25,h=7,rounding=1.5)
{
tag ("remove") screw_hole("M6x1.5,7.01",anchor=CENTER,
thread=true,bevel=0.5);
};

This is quick enough. (not bothered with OP dimensions, nor thread)
