I have a set of blades in a milling machine that requires a 7/16" thick
blades. How do you get the curve at the beginning of the sharpened edges?
I tried swept cut, failed to give that curve closest to the center of this similar blade.

Can you post an image to show what you want
Use the Cut Sweep Feature...
Draw a triangle at the end of the wrench handle and on the top of the wrench draw a straight line towards the wrench head and then add a tangent arc at the end of the straight line, close the sketch and use the Cut Sweep Feature... Do you have 2017? can you upload the file??
I have never uploaded so I don't know how.
ok, thanks, I will let you know how it goes. My blade has 3 sides, sharpened front and back, top flat has radii at corners.
like john stated a swept cut will probably be your best option.
specify your desired angle for the cutting edge. draw a path sketch on top that starts from the initial angle at the handle and then create a spline tangent to that line and also tangent to the OD of the model and boom goes the dynamite.
Highlighted faces, (5 total) requires the knife edge, curve ending slightly inside adjacent radius.
add desired radii first, then perform sweep cut. mirror for repeat instance (helpful if you start by designing a symmetrical part)

A great debate on Zero, Zero, Zero - 0,0,0
It is symmetrical. Origin at center, thickness from Mid-plane. How is it not symmetrical? This is what my customer wants.

Where have you read that "I" said it's Not Symmetrical - Newell Voss only mentioned that a part like this is best designed Symmetrical, again none of us implied that the part you made isn't symmetrical. Here the fatality of the Great American Eclipse was way south of us, and maybe I'm a little off skilter myself, I'm surely not symmetrical by a long shot....
I've never used this forum before, So It seems I was talking to the wrong person. Oh the humanity of it all.
yeah I wasn't attacking your design practices or model by any means. (I don't think it was attached so there is no way I would have even been able to tell..) I was just simply clarifying that if you are to follow my instruction your part would need to be "centered" for the mirroring to work properly. some people need a little extra hand holding with their directions so I figured I would make the comment.
Jay,
John is the one who commits lot of time on the forum to help many and YES, you're talking to the right person
There are only few on the forum (you can see from their ID) from SW, most of us are here to learn and help others without any pay
I guess it's ok if you don't want to show appreciation, but please don't "offend" the helpers - this is not a customer service/technical support !!!
Thanks.
Christian Chu - Times like this we're running a daycare center as well or a psychedelic center
I really don't see how I "attacked " anybody.
Jay,
"Attack" might be a strong word, what I meant "offend"

No offence taken from this side, there's ego egg shells on the floor, just watch where you walk, but just stroll on over to the The "Kitty Dump" - Watercooler - Trash it Here - Food For Thought - Or Whatever else floats your boat, your Car, Truck, BMX or your Horse ;) - to trash this post to oblivion....
..as John suggested earlier.. a sweep cut can do this.. imagine it's a cutter wheel traveling about the edge,.. entering/exiting along the edge?.
Can you attach your *.sldprt file here?
It occurred to me - why not model it the same way it is cut out on the shop floor?
Model revolving cutter.
Cut Sweep with solid Body.
Result?
Simply need to model correct diameter of cutter, set angle and depth of cut.
Sweep.
I think you are on to something here. Thanks
I cant figure out how to upload the file here.
If you have any lead-in/lead-out where the cutter is still in contact with the part - you will need to include that in the sweep path.
J. Mather - the only thing missing in your example is that you have the machining chips hidden, please show them so Jay Brabble knows which way to fixture the part and direction of machining..
learning the sweep cut is the way to go....other options is creating a lot of planes and sketches to get you where you want to go....should have been there before all these nice cutting options came along.....
the other thing that you could do is just sweep the profile of the blade and not worry about the cut....I never worry about what I start with and just make a lot of the parts the way I want them to turn out....
Success! Could not sweep the solid profile as described above so I made a plane tangent to the endpoint of the sweep profile, drew my cut shape directly on that plane and it worked, Thanks everyone!
Since this is your first rodeo on the forum, don't forget to mark the question "Answered" - and list a comprehensive reason why you picked the answer of your choice...
Your sketches are not fully defined.
Your "solution" does not match your problem description?
J. Mather - Good eye Professor
100% - plus if I could - J. Mather - and..... nothing disturbs me more then an "UNDER DEFINED" Sketch, Blue lines in a sketch are an accident waiting to happen, and with the way Jay Brabble was jumping down our throats while we were trying to help, definitely an accident that did happen and hopefully in due respect to everybody, if you come out swinging then you better know where to hit and what you just friggen hit.. Cheers and adios from my end
The angle is not important in this case, I was after a 9/16" to 5/8" bevel.
Not sure why you couldn't use swept cut - see att. file
The that would have given me the correct answer
