Standardized Hole Sizes

[Anonymous]

Right now holes are pretty customizeable, but there is one big problem that I have, which is that there is no standardization. For example, if I wanted an 8 mm counterbored clearance hole in a part, I have to manually look up how oversize the hole should be and enter that information. What is missing is that all of these dimensions - clearance holes, counterbores, etc, are standardized! A much simpler workflow would be to select from the hole standard and then it would automatically generate a clearance hole for an 8 mm bolt, with options to counterbore said hole to the standards that it complies with. 

As shown in this image, all of these dimensions are essentially freeform right now, so I either have to guess or look up counterbore dimensions.

This would make the usability of the hole tool much simpler and quicker - instead of looking up counterbore and clearance depths and diameters for a 10-32 or for whatever bolt I am using every time I need to make a hole, this feature would function just like the threads feature, which has all the standards listed as shown below. Then it is just a matter of assigning all the other parts of a hole to those standards, other than just the taps.

I gree, to be a real 3d CAD program, they definitely need to have this as well as automatic hole callout in drawings

This is HUGE!  I would vote for it a couple of times if I could.

Can this be done by adding the standardized hole size as a user defined parameter?

[Anonymous]

 No, because first of all, user defined parameters do not transfer across documents so every time I would have to re-enter hole sizes as a parameter (and likewise look them up again). Second, even if it was a user defined parameter, that still necessitates looking up standard dimensions for each type of hole needed in a design, which would have to be done regardless of if parameters are used or not. All of these dimensions are very standardized, just like thread sizes, and as they are global standards should not be user input.

For example, if I design a part using some M8s, one has an M8 tapped hole, which is fine because the threads feature contains those dimensions, but one component requires with a counterbore and clearance hole, neither of which are actually 8 mm in diameter, and standard M8 bolts have a standard head height, which is another dimension for the counterbore - these are all preset engineering dimensions that I have to look up and enter myself for every design.

I think you are an engenierieng. I recomend to have both ways to set up a hole and other parameters for the bolt. The first one with a library and the second one with a full customisation tool. Not everyone have knowledge of the standars. And even if you have it some times you have to search for spcific standard acording the funcion and the material you are using.

I agree - I think a good implementation could be to have the same dimension variables shown, but the option to select a standardized hole size that would autofill those dimension inputs, and then you could change if you needed to adjust for tolerances - again with the M8 example, maybe you select an M8 hole with a counterbore, and it autofills all the dimensional info, but you know you're going to need a slightly larger tolerance on your clearance hole so you can increase that manually based on the autofill data - maybe it originally states 8.8 mm diameter as a clearance fit and you can adjust that value to 8.9, but I don't think you should have to start with no standards at all.

Hard to believe the product has went so long with out them.  

[bxliu]

Yeah, they already have this feature in Autodesk inventor and solidworks, but I agree they should allow a user defined library as well for none standard parts (e.g. Pem nut mounting holes)

Thank you for your idea, this is getting changed to future consideration, as it is a part of our plan to combine the hole and thread tools.  Once work is started, this idea will be changed to accepted.

The ability to project the holes to a sketch would also be helpful "checkbox"

[Anonymous]

I see in the roadmap for product development that 2D hole callouts has dropped off.  Heavy Sigh.

@Anonymous,

The team plans on starting this at the end of the year once our move and align project is done, its part of a larger hole and thread project.

Ok, thanks for the update.

A definite must have! 

An option I'm used to from elsewhere is to offer 3 choices of tolerance: tight, normal, loose. 

This auto populates the dimensions for the hole but these are all able to be modified immediately.

Wanted to post a comment to try to get traction on this request.       

I've used the standardized hole feature on OnShape and is a real time saver. 

Would greatly appreciate getting this feature soon.

Yes, the way holes are handled in Fusion 360 is primitive.  But improving it would not be hard, just a changed to the GUI.

The concept is simple:  The user specifies what goes inside the hole and then the hole is made to fit the fastener with the correct clearance.  The user selects from a list of fasteners.   Of course the next request is to be able to add to this list.   

Once I've specified all the fasteners, there are things you might do like keeping a list of them so I can make a BOM or callouts on a drawing

[Juha.Kuusama]

This would be great to have.

> An option I'm used to from elsewhere is to offer 3 choices of tolerance: tight, normal, loose. 

And if the implementation is great, the choices would be user editable, have an option for custom names and have a global change ability. For example, I need to oversize holes to prototype with my 3D printer, so in my case, I would have tolerance choices of "3D printer" and "Production, normal".

> The user specifies what goes inside the hole and then the hole is made to fit the fastener with the correct clearance.  The user selects from a list of fasteners.   Of course the next request is to be able to add to this list. 

And how cool would it be if the fasteners would be added automatically? Even if the user builds the list herself, it would be a huge timesaver: Let's imagine I have somewhere a collection of models, including a model of M5 bolt, washer, another washer and a nut. I've specified that the distance between two washers is the connection, and the bolt length choices are these. Then, when building a design, I specify that "from this point to this surface, fastening from my library". A selection tool pops up, I select my "M5-washer-washer-bolt". Fusion 360 takes the model, figures out that 10mm bolt is too short but 12mm is long enough, and puts all of these in. This would be huge!

I think that in the last big machine design I did, some 70%+ of the time used was putting in the bolts, nuts and washers. Ok, it was using another program; with Fusion 360 single step joints that would  have been less tedious. And now thinking of this, I'm not sure if I'm writing about hole sizes anymore, but rather about a glorified joint type! Sorry about threadjack! 🙂

[albertson.chris]

Yes. Please, a way to make holes based on the fastener. Even if I have to
model every screw, washer and rivet myself. It would save so much time if
I could just say "put THAT fasters at THAT centerline".

Even better if the fasters name could be symbolic so I could change out 200
screws by changing the definitions if the screw name.

Then if Fusion could handle thread tolerances all the much better

Agree that this would be great feature for Fusion 360 to add however seeing as we are now more than a year and a half since the original post it doesn't seem like it will happen? Which is surprising since, as mentioned, this is already a feature within Inventor so Autodesk recognizes the benefit elsewhere.

Any update?  Has this been dropped from consideration?

[bxliu]

Yep, no update for a year on a critical tool. This is why I can't recommend Fusion 360 for any professional use. It will just drive people crazy to have to create manual callouts every time.
