Chamffering a bolt head using sketch?

[Anonymous]

In this tutorial it worked just fine. I followed step by step but it behaved very differently when I tried it. Here's a video of what I mean:

WHen I try it:

You could just use the Chamfer tool for that and adjust the angles, but to do it as in the tutorial to simulate a turned end you need to create a closed sketch profile, which will be indicated by the fill color. There can’t be any gaps in the sketch. The only line that really matters is the one that cuts the top of the bolt. You are letting your sketch lines snap to features on the bolt, which fixes them and ends them- they don't extend far enough. Make the lower chamfer line a lot longer, then add lines to make a closed triangle.

Once you have a closed sketch, change the view to be able to see the top surface, and select the revolve tool, just as in the tutorial. You then select the profile and the axis for revolution, which in the tutorial is the origin. If you bolt is not on the origin you can create an axis through cylinder from the construction menu and use that.

Have a look through this thread hex-chamfer I've attached an example part to post #5 you can experiment with.

Also I understand your wanting to know how to do the steps to create a bolt, but in case you didn't know there is a bolt script built into fusion that makes it really easy to create a bolt in seconds. To run the script click Add-ins button -> Scripts and add-in -> Bolt -> Run button in the bottom right of the popup window. Set all your needed parameters and its done.

Once the bolt is created you can step through the timeline to see each step and all sketches which will also help you to understand what all has to be done.

I hope this helps.

I almost forgot if you need the threads modeled, right click on the threads feature and select edit feature and check the box modeled threads.

Hey, thanks, that may be the problem. I'll get back on it and report back.

That would definitely simplify things. Having a library of fasteners like that is incredibly time saving.

[PhilProcarioJr]

Even aside from the time saving you have the timeline and can step through the creation of the bolt and see exactly how the chamfer is created and tool settings.

The Insert McMaster-Carr component can also be very useful, particularly for oddball fasteners:
