How can we make a ring ?

craouette · Posted: Sat Jan 29, 2011 4:29 pm Post subject:

create a 2D closed curve.
move it along the X axis... the distance to the y axis defines the ring radius.
activate the lath tool
move/size/rotate the curve to set the ring you want.
press ok
that's it.

the lath tool produce vases/glasses when used on 2D open curves, rings when used on 2D closed curves.

i got that trying to make the ring with circle 2d close curve.

that is not bad but not a ring.

edit the lath parameters subDiv1 and SubDiv2...
They are set to the minimum in your screenshot.

Very good tool perfect

I started to hunderstand a bit better the 2D closed curve and the lathe

2D closed curve are différente from normal one in what.

can we draw a 2d normal curve and close it or not they are two différentes entities.

What is Seam
What is mark

seam is used for uv unwrapping.
mark for selection set and rendering.

Can you help me please?

I am trying to follow this thread and I cannot create a ring following along.

I
1/ Create a 2D Closed
2/ Select Circle
3/ Hit Enter
4/ Select Lathe
All I get is a sphere, am I missing a step ?

Thanks

yes, move the circle away from the world center... you're just getting a torus of radius 0 otherwise... and it looks like a sphere!

When we make a 2 2d close and then leave with "ok" selection and
if we want to go back in 2D it does'nt work we cant select a second 2D shape .So
if we want to boolean it just impossible.
or we have to make boolean in following the creation of the second shape....
If we succeed in making the boolean :
we can't rotate or move... the result 2D shape boolean after applaying the lath and (annul) .
we got always the same result. eccept if we edit the shape but not always

craouette · Posted: Sun Jan 30, 2011 9:21 am Post subject:

Yes, that is true. boolean can only work in one 2D closed curve section.
after a boolean, you need to move the point of view a little to be able to rotate or move. I will correct this.
For the rest, I am not sure to understand... sorry.
