Ability to create helix spring with spring eyes

andreas_scholzandreas_scholz Member Posts: 14 ✭
in Product Feedback
I tried to create a helix spring with spring eyes one each end. Helix creation is no problem. Spring eyes I defined with a sketch and used composite curve to have a single guide curve for the sweep. I miss the functionality to add a 3D-corner with defined radius. Spring does not look fine at the moment.

    I have moved this over to the Product feedback since this is a very specific need.  This could be done as a FeatureScript and features like this are the reason we created the language.  It does not make sense to add this to our helix tool but would make sense for a spring featurescript.

    Hi lougallo,
    the possibility to add 3D-corners is not limited to create helix springs. This was the actual problem I had. It would also be useful to add 3D-corners between any other curves that intersect or are connected. Perhaps FeatureScript would be a solution as well. But I am not familiar to programming.

    while there is not 3d sketching functionality you may try to use briging curve

    Thank You for the hint. It is not exactly what I need (missing defined 3D-radius), but sufficient for the moment.

    One thing to keep in mind is that a "3D corner" cannot always be an arc: if tangent lines to the two curves are not parallel and do not intersect in 3D (e.g., in the case shown), there is no arc that is tangent to both curves.

    It is possible to build this with normal features, though it takes a few:

    Thanks a lot for this solution. It is a little bit round the corner, but helpful!

    @andreas_scholz - Part Studio 2 in the Doc above has a better solution

    Try this one, I think it has the transition your after, it was done a long time again and would be a lot easier now with the projected and composite curve like to mention, I was thinking would be also good to have variables to control this too. Just waiting for configurations to make a really nice version of this. Hope it helps.

    It would be nice to be able to project a helix curve on a sketch curve in Onshape, like what can apparently be done in Solidworks as shown in this video: https://youtu.be/de1J0zSc_Q8?t=205

    @cedric_eveleigh392 that’s just a 2 sketch projection which can be done in Onshape.

    Using the "Projected curve" feature?
