    How to close this geometry?

    Hello

    Can you guys please help me closing this geometry?

    I have tried to sweep the horizontal curve with the vertical curve (marked red arrow) but it doesn't close - or makes it smooth.

    What to do? :-) It's really appreciated.

    Place a point at the intersection of the guide curves you are trying to use and use the loft command. Chose the point and the open surface as your sections. Then tweak your ratios as required.

    You can also use the Dupedge (Duplicate Edges) command to create a curve for that open edge if you don't have it.
    Split the resulting curve vertically using that vertical staple-looking line.

    Then, use the CrvNetwork (Network Curve) command and select the three vertical lines, then the cross-section horizontal line, and it'll create a nice open surface that should match the tangency of the one you've got, there.
