- Join me behind the scenes for another of my single-take rehearsals for demos that I am prepping for, test-driving new concepts, or generally practicing. Usually recorded late after all my normal work is done, you might enjoy some of the tips and tricks I hope to offer.
There is so much to show for Onshape's surfacing capabilities, especially given the huge number of enhancements dropping every 3 weeks. Since mid-2022 up until today (June 2023) we've drastically increased the depth and breadth of surfacing in Onshape.
Here are a few little snippets that demonstrate just a few of the new, old and useful things... emphasis on diagnostics, Bridging curve, Boundary surface and some other goodies.
The completed (clean) model is in the public doc: cad.onshape.com/documents/2ac...
Zebra stripes UI is now located at the bottom right.
Yes we consolidated the analysis toolset to the lower right - including zebras, but also for example curvature color map, dihedral, and more.
I’d love to see a deep dive on Face Blend specifically. There are so many inputs and options to wrap my brain around!
Yes I can definitely look at doing some deep dives down the Face blend rabbit hole... There's a lot to unpack!
Love your content!!
this is pretty awesome. surfaces are still something i never use since im still relatively new to the game, but looks like a great tool to have.
That's great! You know a lot of people don't realize the depth of the surfacing tools we offer. They are so well integrated into the rest of the Part studio that it's easy to skip over them since they are not sticking out in their own. Once you know though...
Can these types of line aberrations occur from projecting a new control line from 2 previous lines?
Yes, projecting two clean sketches can certainly result in something that is quite "busy" in terms of the underlying mathematics. The geometry kernel (in our case Parasolid) will determine the projected spline and place the control points and knots accordingly. It is up to the user and/or application to determine if they want to reapproximate, simplify, rebuild it... Depending on the downstream use this may or may not be necessary. In the initial case I showed it was a truly nasty curve, and I'm not certain how it got to be that way! (I don't know the source of the original data) In my case, rebuilding using clean curves was the easiest route.
I've only been using onshape for a week but am really impressed so far! I've spent about 4 hours trying to recreate your horn but I can't get the loft function to work. Is it possible to see your file so I can see what settings you used? Thanks for sharing your expertise!
Sure, I'll add a link in a moment.... check the description.
