I need to create a shallow entry to a hole in the direction of a fluid flow, to help lower the turbulence at the entry/exit points. Having a fillet/chamfer around the whole of the circle would make things worse.
There is no built in option for doing that in the fillet or chamfer menu's, but there are a few ways to do this.
First, you could do it the old fashioned way (hard way) and sketch a profile of the chamfer you want, sweep it around hole as far as you want.
The easiest way would probably be to create a line or plane and use it to "split" the shape, allowing you to select just one part of the edge of the hole to make the feature from, and this would also be the easiest to edit as you could easily redefine the split and redefine the chamfer.
Thanks a bunch.
Look at Variable Radius Fillets.
Kind of hard without seeing a picture or a model, this is what I would do if you can.
How will the feature be manufactured on the real part?
Can you attach image of your "solution"?
J,, I modeled this using a "swept cut" with a tool. The tool takes a path that is adjustable in length by changing one dimension. Had to hammer on this in order to get solidworks to accept a concave tool form. I don't understand what the "geometry must be convex" is all about. This type of fillet could be easily done with a NC mill.
