double curved surface fill

znerol_1znerol_1 Member Posts: 8
Hi everybody,

total onshape beginner, i have had a look at several post regarding the creation of curved survaces but could not find a solution:

I want to create a surface so that the part could be mirrored on each axis without creating any ridges. On each corner the edges meet at 90 degree angles.

Any hint much appreciated.

Cheers,
Loz

    Although I know it is best practice to model with symmetry in mind - this looks like a relatively simple part, and could be a case where it might be easier to model the whole part, then split if you need the smaller segments. I think the split command will do a decent job of keeping the tangent properties and give you a workable part.
    If this workflow doesn't work for you please disregard.

    Here is a sample using a loft. Tangency is maintained at the sketch level and loft(normal to profile). Can be a surface or solid. Won't make any difference. Set to display without edges for a clean look.

    Thanks for helping me with this!

    I managed to solve the issue, I believe my sketches were wrong, as mentioned by by Glen. I created the curves with splines at first that did not actually produce 90 degree angles on the corners. So, after i remade the curves as bezier and ensured that the corners meet at 90 degree the tangency worked

    Here is a couple more options if you're interested. A loft and a fill that are single surfaces with no edge lines.
