Re: Boolean Boss Battle
That… worked… thank you!
Though I'm perplexed, because the INITIAL thing that I tried (before the above approach) was to create the outer surface and then thicken it, but it errored out / didn't want to thicken.
And yet, take the same outer surface, build a flat-bottomed-plug onto it's bottom, and it shells just fine.
I thought thickening and shelling were fundamentally the same thing, in terms of the math being applied to a surface (so if one doesn't work then the other shouldn't either) - is that not so? What's the nuance to appreciate there?
Re: New Custom Feature: Point Overcut
I try so hard (programming is not a normal thing for me) so I'm glad when someone else find my scripts useful.
I made a configurable M4 Nut/Bolt/Washer assembly
FTC robots use M4 fasteners almost exclusively, and besides the fact that Onshape doesn't have Nyloc nuts built-in, I wanted to be able to also include different washers.
Once Inserted into an assembly, it can be copied and reconfigured as-needed.
Washer is Fastened to the head, but the nut is on a Slider

Re: It is possible to change the measurement unit in the drawing from mm to cm
thanks for the reply, but there are no cm, m, etc.

Hi Valentino
Yes, thats possible. On the right side of the screen just like shown in the picture below:
Re: Boolean Boss Battle
Hi Erik,
In general, try and avoid the fillets being there already when thickening. when the thicken becomes self intersecting, it will create errors.
Shell CAN also run into these issues, but a little less likely.
I think your approach of adding/subtracting could also have worked if you'd have applied the fillet afterwards.
In building the positive and negative tools including the fillets to unite later, tolerance errors may creep into the fillets that will create problems in the unite/subract operation.downstream. Onshape is more robust handling these things than legacy CAD, but it's still not the best approach.
Re: Boolean operation results in non-manifold body
to simplify: this error often comes up when parts are just touching (sometime tangentially).
The underlying model will have difficulty deciding what's in and out after uniting. This leads to errors as the models become more complicated and underlying CAD tolerances stack up. so what will work in simple geometry, may not with more complicated models.
so make sure there's a gap or a decent interference before uniting… A small 0.1mm move face feature before a unite is not a pretty way, but it works. .
Re: Best way to place a construction line from offset of circle centre to circumference?
The slot tool is convenient, but you can also just sketch some lines and arcs with the right parallel and tangent constraints and get the same result. There are so many different ways to sketch this.
