Driving a fillet through a point

Question asked by Larry Davis on Mar 19, 2017

Is there a way in Solidworks to create a fillet and drive the radius of that fillet so that the fillet goes perfectly through a nearby vertex? In Creo this is a trivial achievement as the radius is entered "by value" or "through vertex." Perhaps there is a trick to achieving this in SW?


One idea I've tried (which is crazy but in theory works) is to try to sketch a circle through the vertex that is tangent to the surfaces. In other words, sketch a cross section of the fillet in advance, note the radius, and then set the fillet radius value to match. Using this method, I have found that it's nearly impossible to nail it perfectly because of precision issues (i.e. number of decimal places).
