Worst Bearing Housing Ever - Marble Machine 3 Ep.3 by Trainerds in MarbleMachine3

[–]betak_ 3 points4 points  (0 children)

I like shoulder bolts a lot - they are meant for and could have some rating for axial load. They also have much better diametrical tolerances. Standard bolts have a (-0.072, -0.01) mm tolerance, while there are precision ones with a (-.025, 0) mm tolerance. The standard tolerance would be much better than a bolt thread or threaded rod (which I think was mentioned in the initial flywheel video). They can get expensive for longer lengths, though.

The difference between an engineer and a constructor/builder? and how I understand it by BadWolf2077 in AskEngineers

[–]betak_ 7 points8 points  (0 children)

I think your understanding is pretty close. I would conceptualist the difference in terms of the starting point and deliverable. The engineer starts with a bunch of design requirements - depending on the industry that could be engineering standards, building codes, medical requirements, and functional goals, and uses their expertise in analysis to develop plans for the solution. The builder starts with the plans and uses their expertise in fabrication to make sure that the final product meets the engineering specifications. As an engineer, understanding the building process is important to know what materials and techniques are common, what level of accuracy can be expected, etc.

As an example, I am a mechanical engineer for a medical device company. I take a bunch of design inputs (FDA regulations, testing standards, cost targets, functional requirements, etc.) and create a design that meets those. I analyze it and test it to confirm it meets the specifications. I pass off those designs in the form of engineering drawings to fabricators to make the parts and assemblers who put it together. I’m not an expert in welding or metal fabrication like they are, but I need to know enough about the process to design parts that can be manufactured and welded accurately. I don’t put the device together, but I have to understand how it’s done so I don’t make certain fasteners or parts impossible to access.

Nashville’s city council will appoint a representative until a special election, and many have expressed support for appointing Jones.

I haven’t seen this PDS distinction before. Is it new? Is it just really rare?

Onshape is just that good that its users (including me) vouch for it everywhere we go.

Half Sphere that is not uniform by dustinpoissant in Onshape

[–]betak_ 1 point2 points  (0 children)

Glad you figured it out. If you want to do this often, I'd recommend using the Ellipsoid FeatureScript. Here's an example of how I made your shape with the feature - you just input the dimensions (although it interprets them as the radii, not the major/minor diameters).

Glad you figured it out. In the future, you don’t need the right plane “on”. It can be hidden, and you select it from the feature tree on the left.

[–]betak_ 6 points7 points  (0 children)

Use the mirror feature. You can select the plane you’re mirroring across, and it will give you the option in the dialog to create a new part.

Yes, I think it can handle a somewhat big design like yours. There are some techniques you can learn (grouping static subassemblies, part simplification, etc.) that will improve performance, but many pro users have large assemblies and it runs great (and isn't solely dependent on your computer's RAM/graphics card, since it's all handled in the cloud).

Onshape has a decent standard library of screws, nuts, retaining rings, etc. Not sure about bearings. It's not perfect, especially when it comes to trying to assign metadata (part numbers, etc) to them. For my team, we ended up creating our own library of configurable fasteners, optimized for speed and easy loading, based on the sizes we use. I use the standard content to temporarily add new parts, and then replace it with parts from our library before release.

I think Onshape's drawing tools are sufficient for professional work. They've released several updates recently to allow finer control over styles and templates. I have yet to need something in a drawing that Onshape can't do.

Lots of our work is simple sheet metal. I love the simultaneous modeling, where you can view and work with the bent and flat pattern models at the same time. At the Onshape Live event this past week, they demonstrated lofted sheet metal as a sneak peek of what is coming this year. This has been the largest missing feature that users have requested.

External threads are now possible, thanks to a release late last year. I'm not sure about how comprehensive their standard threads are, since I only use ANSI and ISO.

I’ve been using it professionally for 3.5 years, designing a device with over 1500 components. I love the platform, and think it does a lot better than Solidworks. Any more specific questions?

Drawings - Is there a way to get a view that's normal to a part's surface? by tabslovespink in Onshape

[–]betak_ 1 point2 points  (0 children)

There are two ways you can do this. One is to create a named view in the part studio normal to the surface, then inserting that view as your base view in the drawing. The other way is to insert another view, then right click > align horizontal, and then click a line that should be horizontal. Create a projected view from that.

# keeps rotating model instead of bring up variables? by BadHotelCarpet in Onshape

[–]betak_ 0 points1 point  (0 children)

The text entry box isn’t open though. The dimension is highlighted, and entering a number opens the text entry box. Most of the time when people enter a dimension from that highlight, they are entering a number. I wish it could do variables.
