How do you determine the hoop corner radius when creating new hoops? I use all the Mighty hoops BTW

Hi Gina,

To create a new Hoop:
Go to Options > Hoop tab.
Click Create
Select Format 'Round Rectangle'.
Enter desired measurements including the corner radius and the hoop expected size.

Kindly see attachment.

Let us know if this helps. Thank you.

Kind regards,
Karla

Hi Gina,
The corner radius, R can be calculated using the formula R = (H/2)+(W²/8H)
where:
W - length of the chord defining the base of the arc
H - height measured at the midpoint of the arc's base.

See attached ArcRadius.png.

You will have to draw an arc of the corner on a piece of paper, and measure W and H. Will work if the the hoop is a true "Round Rectangle"

See www.mathopenref.com/arcradius.html for more details.

Thanks Pras - that's too hard for me :-) I'll just leave it at the default and hope for the best that I don't hit the edge of my hoop.

Don't know why I didn't of this before - I called the manufacturer :-)
