Loft Twisting

shai_perednikshai_perednik Member Posts: 56 ✭✭
I'm struggling with lofting from a big rectangle to a smaller one.  Seems no matter which verticies I match, even though they both have 4 segments, I get this twisting effect, like the segments don't line up.  Any ideas what I'm doing wrong here?  Doc is @ https://cad.onshape.com/documents/14f3d01d62b5237f728896c5/w/40e0afc950b8ca0dfecf9ef8/e/48d62775ba30708d4aae1614

    yes, please do submit a ticket. I'm suspecting a problem with the sketch imprint on the red circular face.

    @ shai_perednik .Without matching vertices also it should work but it is not working even if you select the vertices .
    As a work around Try this,




    Extra face can be removed by using Delete face option,

    Trying this loft from the yellow parts bottom face (rectangle) to the face of the gray round part (or to the sketch), and neither generate properly.  I believe this is because of the mentioned above bug.

    Hi again Shai,

    I think the bug here is due to lofting between sketches.  Can you try your loft between faces of geometry rather than sketches? If there isn't a face that perfectly matches your sketch you can first extrude-new your sketch away from the loft, use it as a parameter to the loft, and delete it as I did in my first workaround.

    Let us know if that works, Thanks!

    Congratulations - you just met Dr Tosun (Elif) :)
    Besides being an awesome person, she also wrote our loft. Now, it might not be for me to say Onshape is awesome (I am biased), but someone else might say "it's a pretty cool CAD company when you can ask the developer that wrote the code why your thing doesn't work"!
