Rail Not Smooth Lofting Error, and Face Not Creating

[et_cetera]

Hi!

I'm trying to loft between 2 points and many sketches in between (see screenshot below). However, when I try to use one of my rails, it tells me that my rail is not smooth. The sketch clearly shows that the rail is tangent at that point. Is there a way I can fix this?

Additionally, one of my sketches (called "front rails") won't become a closed shape for some reason. I had to use the patch function to create a face, but can I change something in my sketch to make it closed so I don't have to use the workaround?

All help is very appreciated. Thanks! 🙂

strange.  That will take some investigation.  Thanks for sharing the model.

If I try to loft the profiles separately, the points are all lofting to the wrong things. Does this have anything to do with the problems above? Screenshot attached below

I think that is a separate thing, looks like a point mapping issue.  Still looking at the other problem...

@et_cetera - I was able to get this to go in 2 lofts (avoiding the strange "not smooth" error).  The problem is:  there is an undesirable lump at one end that I don't understand:

The keys are:

1. make the second loft tangent to the results of the first
2. turn off chaining, to make sure that you can select the side rails as two rails, not one
3. don't panic when it fails mid-loft - it seems to correct when you add the rails

I was able to get rid of that lump by changing that first profile from a point profile to a sketch profile:

which resulted in a much better answer.  I suspect the same could be done at the other end, too, but I'll leave you to experiment with that

thanks jeff, your help was amazing
