Hello, I have here a snapshot and I need to generate a curve like what is shown..Is there a way? 

Thank you

Hi,

See attached.  I imported your image and then trace it.

Does that work?

Thanks,
Brian

You didn't include a crucial piece of information: what version of Inventor are you using?

The attached part file (Inventor 2020) contains a 3D sketch of a spiral matching your image, I think.  Here's what it looks like:

Edit: I see on re-examining the image that I didn't get the Pitch parameter quite correct-- should be 2.25mm instead of 2.00.  But easily corrected.

Edit #2: Still not correct.  The diameter should be 2.00mm, not 1.00mm.
