Hi All.  There is a new public document called Learn Onshape - Model and Movie - IRIS Shutter.  In it is a PDF as well as the models with links to two video.  Use RMB click to open the videos in their own tab or windows.

Let me know if you think it is helpful in learning Onshape and how the experience is.  All feedback welcome.

Thanks

@DarrenHenry I have to say, this demo is absolutely phenomenal.

It's clean, concise, and focuses on one of the core strengths of OS - the ability to manage top-down and bottom-up simultaneously.

I do have one question though - in a production setting, you can't just "boolean" one part from another, because you need to account for manufacturing tolerances. This fact is really what keeps bottom-up design alive. The world is chock full of "ten thou working clearances", so how do you recommend OS users account for that in this type of workflow?

May I recommend an option in Boolean to account for working tolerances? Ideally, the user would be given a choice to either subtract material from one part, the other, or split the difference. Just a thought...

One option for modeled clearances right now, is to do a 'move face' after the boolean operation. That's what I often do in SolidWorks as well.

I see... That would make more sense for molded/cast parts.

For machined parts it seems like a bit more work than just sketching in the actual dims in the first place (The B-U approach). This also allows for easy tol stacks and "shown/driving dimensions" on drawings. However, since neither of these down-stream capabilities are currently available in OS, the point is moot. "For now"...

Hi.  The idea of a boolean with clearance is a topic we have been discussing.  Not a simple problem because you may want different offsets in different directions.  I think top down procedures can still work either with a move face, or by simply offsetting sketch entities.  Top down is still the approach that i would use because it simplifies updates and edits.  Its a great discussion worth having.

Hi, this is a very old thread and onshape has developed a lot since then. I'd recommend looking in the Learning Centre (under the help menu) instead.

Yeah I was just really interested in how it worked so was looking forward to the additional content about it.
