Designing an Anchor Base (Tutorial)

In this Onshape #tutorial, our resident Onshape superstar @tootalltoby will create the geometry shown on the 2D print of the ANCHOR BASE, and calculate the mass of this model. Along the way he uses tools like sketches, arcs, planes, and counterbores to create a perfect model!

Thanks for showing the counterbore workflow! Was doing it the long way with two circles, two extrusions, very time consuming.

[@TooTallToby]

Awesome! Yeah I used to do it the long way around too - Shoutout to AIRWICK for showing me the way!

[@geoffphil]

The high standard continues. Thanks for another excellent video TTT.

[@TooTallToby]

Thanks Geoff!

[@constellations8572]

Great explanation! Thank you very much for these high quality videos!

[@TooTallToby]

Awww yeah! Glad these help!

Another WOW quick tip packed with features showing how OnShape is so much more powerful and intuitive than Fusion 360. I am so glad I began this transition away for F360. Your technique, while timed, is not rushed; even the time to plan is well spent. The Counterbore and preselecting features to add the plane - master these for huge time savings.

[@TooTallToby]

Yes indeed! Thanks for the kind words and glad these tutorials are helpful!

Nice! Mate connectors FTW!
By the way the downside of using the plane for the angle is that you end up with your sketch axes at a weird angle so you can't just use the "standard" rectangle tool and lines won't snap as easily where you want them.
One way around this is to place your sketch directly with a mate connector. Alternatively, you can also create the shape straight and use a move face with rotate to set the angle.
I thought I had a solve of this one on my channel but I don't...
Another tip is that if you use a center point rectangle to locate the holes you can just select your sketch in the feature tree in the hole tool instead of selecting each corner individually (it will ignore the center pt of the rectangle).
Bonus tip: you don't need to put a space when putting in the units (just type 3in) so you could save a whole of three key strokes!

Another golden tip here for holes - thanks airwick :)

[@TooTallToby]

Oh man these excellent time saving tips just keep coming!! Thanks Airwick!

I did this anchor base before you explained it as an exercise as I've been goofing around with onshape for enough time now to think Iwas up for the challenge.
There is a measurement missing on the tombstone, we can't know for sure when it starts arching on the top. By looking at the sketch, it seems that the arc starts at the same height as the middle of the hole so 2 inches from the base.
Based on that I did the part ... took me more than 10 minutes though and I made other building choices than yours ... but we have the same piece at the end and it was a fun exercise to do.
Now that i have seen your tutorial, I learned how to get it a lot faster ... thanks mate connector

[@TooTallToby]

Yup you are correct - I just looked again and there should be a radius dimension originating from the center of the tombstone/counterbore, to clarify that the arch of the tombstone is centered at that same location. Good catch! 😁 Very glad to hear that you're now able to build this thing faster too!! 😀

[@lamb7283]

Thank you.

[@TooTallToby]

My pleasure!

[@stefanwuttig]

if you are making first the fillets you don't have to draw an extra rectangle for the holes. You kann use the midpoint of the filets. Also tthere is no need for an extra plane for the thombstone. you kan draw an aligned rectangle on the upper surface of the bottom part, extrude it and some filets, make your hole and then you can change the angle of the thombstone with the "Fläche verschieben" tool ( Idon't know the english word for this tool ;-) )

[@TooTallToby]

Great suggestions! Thanks!!

[@calzord]

Toby your a G. Thanks for being too tall.

[@TooTallToby]

lol - my pleasure 🙂
