How to create a curved ramp?

[ruieduardonunes]

Hi,

I'm trying to build a curved ramp aroun an axis on inventor pro 2015. I tried to draw a 3d sketch of the curve and then project it to surface. Then I tried to revolve with the path being the projected line but I had no results. What is the better way to do this.

Thanks in advance for your help.

Is the curve a helix?

Use the Coil command.

Attach your attempt here.

Hi,

I attached the file as you asked. The objective was to make a 180º curved ramp. In the file you will find my atempt. I was not able to make it grow any further.

I got lost on the first sketch.

Can you explain where the dimension for the 2mm circles comes from (see attached)?

Hi,

I already managed to do the total ramp but with stairs. I wanted this ramp to be smooth. I attached the file. 

Thanks for the help.

Best regards.

I am having great difficulty understanding your design intent - but maybe something like attached?

Hi! I played around with it for a few minutes and came up with this solution using Rect Pattern along Helical Path workflow. Please take a look and see if it works for you.

Thanks!

Yes, I'm sorry. I haven't seen the attachment.

Thanks for your help and time. I will now study your process.

Hi.

I had already done something like you describe here. But the objective was to get a smooth ramp. The previous comment answered my question.

Thanks for the help.

Best regards.
