Re: How can you smoothly connect two circles on different planes with a tube?
Thanks @eric_pesty. I've taken a look at that. At first, I thought it wouldn't work, as it seemed more like free-hand 3D line drawing rather than calculated, but by playing with it, I figured out the "anchor" variables. I've managed to get it to do very nearly what I need by having a line coming out from the face of the… -
Re: How can you smoothly connect two circles on different planes with a tube?
Keep in mind one of the OP's initial requirement was for the tube to be as short as possible...and I assume that is the total length. To accomplish this the bend radius would need to match the tube radius, wouldn't it....or very close? I see this as the top edge and bottom edge of the bend sections being near tangental to… -
How can you smoothly connect two circles on different planes with a tube?
How can you smoothly connect two circles on different planes with a tube? The tube must have constant diameter along its length. The tube must be the shortest possible (i.e. a straight tube with curved connections on either end). I'm aware of "3D fit spline", which you could use to join the centres of the two circles and… -
Re: How can you smoothly connect two circles on different planes with a tube?
Thanks @john_lopez363. That's almost perfect. I managed to get to that solution a few attempts back, however I discarded it because the lengths of the reference lines are manually set, through trial and error. And you end up with something not quite perfect - screenshot taken from your doc: The straight section before the… -
Re: How can you smoothly connect two circles on different planes with a tube?
@christopher_brett Using the 3D Lines FS plus a couple of reference lines to help the FS define the vertices...you get this. The length of the reference lines are not equal because the angles between the 3D Line and the Front plane and Top plane are not equal. You can make the reference lines longer, but make those lines… -
Re: How can you smoothly connect two circles on different planes with a tube?
Thanks @martin_kopplow, that is awesome! I was trying to find a way of getting Onshape to do the work via constraints, but got tripped up by only being able to constrain in 2 dimensions at a time, and not being able to constrain across sketches. I hadn't thought of using an assembly to constrain in 3 dimensions and then… -
Re: How can you smoothly connect two circles on different planes with a tube?
I've put a clean example (without all the random experiments) in the https://cad.onshape.com/documents/bca273998578cc2603c134a3/w/4c4563f13cf1b97e498478d4/e/5c7a16b4af3fc5de975969f6?renderMode=0&uiState=6615102754861d1b1623fee9 in the "Plain Geometry Example" part studio. I think the issue is that I've got the wrong arc on…
