Trouble Modeling ASTM E8 Tensile Specimen Radius [ Edited ]

[#1]

See attached photo. I am trying to model this, but the radius on the tensile specimen is kind of "stretched out". Simply using the fillet tool (with a .250 radius fillet) doesn't work. What do I need to do to make the radius?

This is a FLAT specimen not a cylindrical specimen!

Thanks

Sketch the profile and Revolve it.

Ahh alright I will give that a shot!

Wait...sorry I should have said this - it is a FLAT specimen not cylindrical.

Yeah, I just saw that.  Sketch the profile and extrude it.

Edge Blend should also work (this was with default settings and just dragging handles):

Thanks will give that a go!

"Simply using the fillet tool (with a .250 radius fillet) doesn't work."

Do you get a message about "not able to terminate blend face..."?

If so, in the edge blend dialog, expand the "overflow resolutions" section and turn on the "allowed overflow resolution" options (all three). Turning these options on will allow what used to be known as a "cliff edge" blend.
