<div dir="ltr"><br><div>Hi,</div><div><br></div><div>I'm just learning gmsh from the tutorial, and I have some questions regarding gmsh geometry design, </div><div><br></div><div>I have two Bsplines with common start and end points that are not coplanar to each other. A ruled surface cannot be created with a loop from these two Bsplines because the loop needs to have at least 3 lines.</div>
<div><br></div><div>My initial idea was to define a third line by creating a third Bspline, whose start point and end point where the middle points of the two original Bsplines, thus producing 3 loops of 3 lines each, and I would be able to create a ruled surface from those loops</div>
<div><br></div><div>But how could I create such third Bspline? I don't understand how the "split" line functionality in gmsh works. (It doesn't seem to be mentioned in the tutorial either), basically it seems to ask for a "split point" but when I click somewhere on the line nothing happens. If I add a point that intersects the line somewhere the selection of that point seems to work, but then I click 'e' to finish selection and nothing happens; when I hover on each side of the line both are labeled as the original line, so no split seems to actually happen</div>
<div><br></div><div>I tried to find how to intersect the original Bsplines with a plane, but I couldn't find that functionality anywhere</div><div><br></div><div>Any ideas?</div><div><br></div><div>thanks</div></div>
