BOLT - How to determine center point to draw the Radii

Hi,

 

I am trying to draw a bolt in solidworks. I have certain dimensions of the bolt which I measured using calipers and comparator machine. But I am unable to draw the Radii and undercut in the bolts.

 

I am attaching a drawing of my model with question mark on spots where I have doubt.

 

1. The larger Radii of the bolt - I am not sure where is the center point located to draw the arc? i can just create a random point of center but I know it is not the right way to do it.

 

2. Smaller / Undercut Radii - I am again not sure of the center point to draw the arc. Initially I drew two circles on top & bottom with two different radii and used LOFT option to create a fillet like arc to join two circles, but when I import my part to drawing I was not able to show what is the radius of the arc.

 

Help me to solve this issue. I appreciate all your help. Thank you
