helix 3D, hatch

[Kosjenka]

I've made 2 parallel helix in 3D and I want to hatch it to make spiral stairs or ramp. But, I couldn't hatch it and I couldn't make region and boundary. Can somebodey help me, please? :oops:

Don't understand why you would hatch to make stairs or ramp?

Connect the bottoms with a line.

Sweep the line along one of the helixes.

Thicken (for ramp).

[Kosjenka]

well, because I don't know how to do it.

I don't understand how to sweep a line along one spiral...

F1 Sweep

 

You might go through the tutorials in my signature (written for 2007 Dashboard - but the techniques are the same using the Ribbon interface).

 

If you can't figure it out attach what you have completed so far.

[Kosjenka]

it says that it can't sweep... so I'll atach you.banovina, 3D.dwg

I made a few errors in logic.

 

First of all, your outer helix must, of course, be a larger radius than inner helix.

But no matter, you don't need it anyhow - delete it.

 

You added thickness to your line - that isn't what I said to do.

I said Sweep and then Thicken (the command Thicken F1 - on the surface resulting from the Sweep).

 

Worked here?

 

Did you already go through those tutorials I suggested - did you request the sample files?

Now I've done it. thank you very much, it looks great

you could draw a circle at one end, hatch that and then sweep it along the helix path.

Can you attach a file that demonstrates this technique?
