Chamfer issue

Anonymous — Sat, 28 Apr 2018 05:37:09 GMT

Ok ill figure this program eventually. As you can see my chamfer is uneven. I cant figure out how i got it that way but i need to get the chamfer even and to be able to lower increase the angle still.

Thank you.

I'm not sure what you did in your design because

I'm not experienced enough to understand what you did
You did some design steps that are just to complicated (???) to get what you want.

If this is what you're looking for, check the attached file to see what I did.

@lichtzeichenanlage You've actually found another known bug in Fusion, notice how the steep and flatter angles are reversed on the round faces compared to the flat faces. Also note both arrows are pointing down when one should be across. @jeff_strater you might want to take a look at both of the files in this thread.

@Anonymous Quick question, is the part supposed to be from a round bar with 2 flats? The part you,'ve drawn is a rectangle with a D shape either side and is not round. You can make the chamfer with a revolve cut but it might look uneven because it not round.

Here's you can see your sketch with a circle added. Also can you use the photo option to embed images, attached images are a pain to view.

@HughesTooling Thats what i was originally going for the round with two flats but couldn't figure it out so i reverted to that.

@CWBoarder691-

first suggestion. Don't use move the way you are using it. that's a photoshop mindset, and will give you grief eventually. There are occasions when moved can be used to good effect, but in general it's not good practice.

as far as your chamfer goes, the problem is that it's not a chamfer, it's a revolve. (the pictured part would have been made with a lathe)

Here is a screen cast of one approach to making this part

I thought I posted this yesterday, Here's a way to make your part using a circle in a sketch. One bit of advice, don't waste your time using the primitive shapes you have far more control with sketches and extrudes etc.
