With D.LOFT using no ruling alignment, the lofting extends the existing curves beyond the drawn ends whilst running the ruling iterations, when it has finished and comes up with a result, the plugin then trims the surface to the ends of the original curves.
Is it possible to keep the extended surface, then trim the surface by projecting another non-linear curve onto the lofted surface?
In other words, I want to make the ruled surface, but I want to maintain a curved end.
To use your example video of the yacht sails https://www.youtube.com/watch?v=C0RAbqinjeg you can see that the resultant develop-able surface is missing the ‘leech’ curve as it has been chopped straight between the two guide curves.
Also, I noticed that if you select align rulings with both extremities, the plugin no longer projects the rulings beyond the curve ends? If the earlier part of my question is possible, is it also possible to force the plugin to project the surface beyond the curve ends in order to be trimmed to another shape later?
This would be ideal for many purposes, as when not aligning the extremities, the resultant trimmed surface often has deformed ends …
