Create Smooth Arc Curve Thru Several Points

[BrittToolEngineer]

Greetings:

Please find attached an example of points that are plotted in order for an arc to be created through these. Can someone guide me to the best function to create the curve?

Thanks,

Brent

Hi Brent,

I would use both the points and the curve and then just create 3 point arcs through the points which appear to line up with the original curve the best. When finished, make note of the radius values and correct for tangency (new fillet curve or edit fillet) - maybe round to the nearest tenth or hundredth decimal place for the radius value.

One specifies arcs, the other specifies a curve (spline?). Same concept, different techniques.

True, but the pdf drawing shows the curve is dimensioned by a table of points; if it were a circular arc, it would just be called out with a radius or diameter dimension. My best guess is that BrittToolEngineer is trying to replicate a free form shape from paper drawing to CAD model.
