1. Point object at center of hole (choose e.g. top circular edge)

2. Construct reference plane using point and a parallel face

3. Insert sketch, draw centerline down middle of hole, draw circle where you want the groove

4. Cut-revolve operation

To set up that sketch plane, you'll want to first hit the hide/show eye icon in your graphics area, and make sure the view temporary axes button is selected, Second from the top on the right side. That should show the implied axis of your cylindrical hole.

Then you'll go to Features > Reference Geometry > Plane.

You can select a first reference, that being some plane or planar face that you'll want the new plane to be parallel to. Your second reference will be confident to that axis you showed in step 1.

From there, sketch a construction line showing the axis of revolution and the profile of the o-ring grove at the appropriate distance and you're good to go for your revolved cut feature!

Thank y'all for the detailed step-by-step instructions. Those sound like broadly-applicable patterns that will come in handy elsewhere - especially the concept of reference geometry. I think those patterns are more consistent with the overall UI than the Groove/O-ring tool, which are more geared towards specific-part-selection.

Library parts are a little more involved, but useful. I believe there is an included library for o-ring groove features, but I haven't used them myself. Just in case you find yourself doing a lot of them, it might pay off to check out.

The hole wizard tool is similar to the groove tool in that it's more specific application but does a lot of the get dimensions from a book work for you. Or you can spec a m4x.7 threaded hole and it'll grab the tap.drill size, give you options for visualizing the major and minor diameters, etc. Same for counter sinks, choose you fastener type and head clearance and it'll make it deep enough.

This is super valuable for any kind of shaft fits, choose your nominal diameter and desired type of fit and it'll put an appropriately dimensioned hole in the part for you.


Knowing when to use a specific wizard type tool vs build the geometry yourself can take a bit of time but eventually becomes pretty smooth and can save massive amounts of time.

What appealed to me here about the manual approach(s) would be that they're a more general teaching tool, ie would help me do things beyond this use. And I'm not sure how to use the O-ring tool to just put in a width and offset in mm, and it's not clear what unit the tool shows. And once it's placed, I don't think you can change the O-Ring model without deleting and re-adding the tool... Unlike everything else in the software I've seen.

That said, the O-ring tool was very easy to use once I figured out how to add it. A consistent problem with the docs (built-in tutorials, and on SW website) is it'll ask you to click buttons that aren't there, and won't show you how to get them. The tutorials sometimes let you click the button in the tutorial, at which point one will appear from the void in your toolbar... but this doesn't show you where it came from, or why it was missing.

Does anybody know if there is something like this for Fusion, too? I design a lot of stuff that's e.g. a part has a hole in it that an m3 screw goes to; the part it touches will be threaded m3. I'd like to be able to have one "hole" feature and then say "this part gets minor/tap diameter" and "this part gets slip-fit diameter." Then if I want to change it to m4 or m5, just update the base feature and everything propagates through.

Planes, sketches, and axes will set you free. They're incredibly powerful tools. Need to make an odd cut? Project a plane and draw a sketch!

Library stuff is handy, but can really bog things down if you use the smart fasteners or that sort of stuff. It's great for making derived parts, though. Need to make a bolt with a hole in it, or a groove turned in it? Copy a toolbox part then modify it.

The hole wizard is incredibly useful, too. I just wish it would snap to geometry for more than the first hole.

I have no idea for fusion but in SW you'd define those holes separately, one part would get m3 tapped to x depth and the other would get through hole for m3 fastener and you'd have to change them separately but the specific dimensions would auto update.


I was in the process of trying to learn when I got SW at home and I'm not sure if it's from learning SW first but man it's more intuitive. And I'll never forgive fusion from not having an offset both sides function for sketch geometry.

That'd maybe work but I've decided I'll figure out fusion as soon as someone pays me to do so, the licensing getting better for SW and worse for fusion had taken away almost all my interest in learning it.

Also having a CAM seat as well, fusion having CAD and CAM was a huge attraction.

You can open files back and forth between the educational edition and the commercial edition of SolidWorks. However, the educational ones have a little mortarboard icon on them when opened, and it spreads like a virus. Add one educational part to a commercial assembly and the assembly gets tagged with the icon. Save the assembly and every contained part gets tagged. Those parts can go on and spread it to other parts and assemblies. There's no way to remove it.

Does it matter? For your use case, bringing work files home to open in the educational version, no. But you definitely can't edit files from work at home and bring them back in unless you want your whole company's PDM system to get infected

Yeah a little mortarboard icon is fine with me. Once I migrate all my personal files off my work machine I'll never do the opposite.

Even if I did I work at a tiny company that gave me a blank stare when I asked how to access the PDM system when I started. Between that and having half a dozen silo'd projects going at once would stop that from spreading.


On an unrelated note, does anyone have any advice on how to convince my coworker that assemblies exist and are worth using? He constantly creates multibody parts that will end up with like 20 bodies in a part file, including Insert Parted fasteners. I'm not talking about master modeling either, he does this without ever creating assemblies. Protip to people learning Solidworks - pretend multibody doesn't exist until your competent with single bodies.

Hole wizard is great, construction geometry is great, reference geometry is also great. 3d sketches are almost useful EXCEPT for laying out reference geometry stuff really quickly, and laying out curves for lofts and sweeps that are weird.

Learning all your shaft fits can take longer than looking up the dimensions though, I'm still pretty bad at it and cheat most of the time by either drawing everything as nominal and than adjusting my fits in tool selection when I make things or in CAM - benefit of doing the whole thing end to end.

I didn't realize the o-ring tool was a toolbox feature, I've got no idea how to use those and assumed it was more like the hole wizard than it is. Seems really powerful once you get it figured out though.



One of my recent tricks is using more sketches than features, no idea if its good or bad practice but after getting used to layers in Rhino I found separating levels of details in different sketches can be really helpful. I'll draw reference geo to other parts in a sketch, do some big picture layout of my part in a sketch, then go in in new sketches and reference those for half my dimensions as I build solid features but separating it helps me with visual clutter and having common sketches across multiple features without attaching the sketches to other features. I got way to used to being able to hide things and turn layers off in Rhino which doesn't really translate to SW in either thinking or practice, but adding more intentional separation to my sketches has helped.

Mates, tolerance analysis, motion analysis, BOM control, drawings, probably a half dozen other things of varying levels of niceness all depend(?) on assemblies.

Easiest way is to just bully him into using them by either refusing to work on assemblies as part files or just turn his parts into assemblies and then send him the assembly back. Seems way harder to do it this way, every time I work in a multibody file I end up welding things together I didn't want together multiple times.

Another SW question - individual solid parts should be separate Parts, and joined in Assemblies, right? I'm trying to use the snap hook and groove tools, but am unable to select the matching part; the tutorials I've found are ambiguous on this topic, and might imply you're supposed to have the same parts open in the same window (?). How do you approach this? Thank you.

Ie This official tutorial, this step: Select a face to which you mate the bottom of the hook.. It won't let me select the other part when the dialog is open, and exiting the dialog resets the process, or turns it to a 3D sketch.

Edit: After some clicking around, I think the solution is click `Insert` -> `part`. It then moves whatever other part is open into the view. Not sure what other consequences this has etc for "control" of that part, or how to align to (Still can't make the hook due to "not intersecting"); it's ignoring how the parts are mated in the Assembly.)

The workflow for things like that generally assume a multi body single part at that stage of design.

This is because most products of this type, e.g. enclosures, are first made from a single body that is split into halves for injection molding using things like the "Split Line" command. You're then able to save those bodies as linked, separate part files.

Then, in an assembly, you'd incorporate the PCB, fasteners, both halves of the enclosure, etc, and get your BOM and drawings from there.

Unrelated for my fellow CSWE chasers: there are some errata in the Mold Design exam that I'm taking up with SOLIDWORKS. I'll let you know how it goes.

To avoid spoilers but give some workarounds: there is a suspiciously small shrink rate in one question. If you get that one, I would advise removing a zero.

On another series, your mass may not update if you change from a plastic to the mold core and cavity material. It may be worth exporting bodies as a STEP, importing, and then assigning the mold material.

Use your Measure tool to validate that your tooling blocks are actually being extruded as far as you said. Mine was about 0.75mm off, but on a block of that size my mass estimate was hundreds of grams off. Editing the tooling split feature showed the correct dimension, so just be careful.

I hope those can help!

Dominoes
Sep 20, 2007

Thanks homie. Perhaps it's better (for initially-3d-printed-parts) to design the hook manually, or perhaps ditch the assembly concept, and save the mutli-body-part as separate STL files when printing.

Edit: Got the feature working using the multi-body part approach, but am a bit unclear how to proceed with overall design here and elsewhere. Maybe multi-body parts for the enclosure, in an assembly with the PCB, buttons, etc.

If you're not needing to like do clearances, simulations, bills of material, motion studies, and things like that, then yeah just go straight to the 3D printer from the part file.

This is one of those things where SOLIDWORKS is obviously built for teams. Change orders coming through, but only having to change one dimension of a "master" part is enormously useful. But if it's all just you, then save yourself the extra 3 steps or whatever to get that all into an assembly and mated properly.

It tracks if you're in the main audience, but it's definitely fucky if you're coming from the hobbyist side like I did.

E: definitely get all that poo poo into an assembly if you're doing more than just an enclosure. Interference and distance checks are enormously useful and can save you a lot of time and filament.

Check out some tutorials on split lines and split commands. The end goal is to get everything into an assembly so you can make use of those interference and clearance tools.
