I use Sweep2 very often because it is the fastest approach I can use in my design process and wish to optimize how I use it. I use Sweep2 most often to extend the side walls of polysurface shells.
I extend the surface edges all at once and then go in with *Sweep2 to complete the job. But I am having an issue with Sweep2 once I switched from designing in Rhino 5 to Rhino 6. It used to be that when I used Sweep2, the surface would sweep along the rails in only one of the two possible directions. But I am noticing now that frequently the surface will sweep in both directions. I wish to prevent this. And I do not wish to trim the rails each time.
I have found that when I check ‘Refit Rails’ in the Sweep2 options dialog, this has limited the sweep to one direction in the cases that I have tried. But by default, the Sweep2 options dialog has this unchecked. Is there a way to alter the default settings of this dialog or to ensure that I can use Sweep2 with the same efficiency and maintain that it will only sweep in one direction?
Attached is an example of these cases. The layers hold the geometry before any commands, after default Sweep2 and after Sweep2 with ‘Refit Rails’ checked. Thanks in advance.Sweep2Question.3dm (241.0 KB)
