Hole Tool & Chamfer Upgrade?

fastwayjim

Would be nice to have a hole tool. Something with a standard library of diameters, and having toggles like counterbore, countersink, drill hole profile, etc.

Also, i'm sure it's being worked on but I haven't seen it mentioned yet - There needs to be more options for the chamfer, such as D X D, D1 X D2, Angle X D, etc.

Agreed. A hole feature would be a huge productivity booster.
I would add:
Threaded holes with (optional) modeled threads. Awesome for 3D printes prototypes.

Thirded! Especially like the idea of a toggle to automatically model threads for 3D printing.

Would also be cool to maybe have an extended library of "holes" for non-typical fasteners, like fully-crossed T-nut fasteners, heat-sink inserts, etc.

@FastwayJim We are working on more chamfer options and will update you all when it pushes.

Suh-weet! Your killing it, @LouGallo!

@LouGallo, I'm looking to chamfer a specific section of a circle not the complete circumference. How can I achieve this? If it hasn't been thought of, will it be a potential upgrade?

**Note that the chain links have sections that are chamfered but not the entire link.

Cheers

@R3L4TIVITY  If I didn't miss something it looks like regular chamfer.

@R3L4TIVITY Onshape does not have end-cap options for their chamfer feature (maybe one day) so there is no way to specify how the chamfer should start and stop.

To create the chamfer shape, use a swept cut.

You will have to use other geometry. A swept section of the tool that would create the chamfer plus revolve cuts of that same section at the end points will get this shape:


For the other details:


You won't be able to use existing geometry easily to get the sweep path; you'll have to offset the sweep path a variable distance from the edge yourself. It can be done...

But as an engineer I have ask; is this level of detail really needed?

I would have to agree with @Traveler_Hauptman : once the parameters become as open-ended as chamfer termination style, the tool will have been elaborated to the point where it's just too unwieldy.

Even if the tool were narrowly focussed to the single situation depicted above, representing a conical end-milling cutter following an arcuate path, then stopping, we're left with an infinite number of possible conical solutions, because the axial depth at which the tool happens to be set will change the location of the cut-revolve axis.

I can see some merit in being able to pick a vertex on an edge, or a plane intersecting an edge, and chamfer up to that entity. Essentially, the chamfer would be "hitting a brick wall"
The modeller could then sketch a cut-revolve on that wall.
However it's relatively easy to workaround within OnS current feature set, by temporarily splitting the body at those locations, chamfering, then re-merging.

It is sometimes problematic realistically modelling the results of 'form tool' milling operations, like a 'scowboat' keyway end, formed by withdrawing a bull-nosed endmilling cutter according to an arc-shaped (in side-view) toolpath.
Solidworks "Solid Sweep" should handle this, as well as the simpler chamfer termination tasks ... but last time I used it, it was unreliable.

@Traveler_Hauptman @Andrew_Troup , Cheers guys for giving me some solutions, will try them.

@Traveler_Hauptman, the use of the specific detailing on the chain is so that the chain can be guided better onto the cogs as a mountain biker rushes down the hill bouncing around. Although there are chain guides that already do a good job, the chain still gets some flex and has potential to miss a tooth from that cog and jamming the chain guide, or derailleur as i found out, making it impossible for you to peddle forward.
