I'm trying to do a very simple swept blend on Revit 2017. The path is an arc and the profile on both sides is a simple rectangular profile. The only difference on each side is that I'm giving the profile slightly different Y-axis offsets. What's particuarly weird is that it depends on what offsets I give them, the swept blend can or can't be created. If I change the offset by just 1cm, it doesn't create the swept blend, but just for trying I gave one profile a 1000m offset and it created it just fine. I attached a couple of screenshots so you can see my problem better. You'll notice that my Revit is in spanish. In the first image, the first profile has a -2.80m offset and the second one a -2.90m offset, and it can't create the swept blend. In the second one, with a -2.80m offset in the first profile and a -2.91m offset and it can create it without any issues. Anything inbetween a -2.80m and -2.91m offset it can't do, so I can either have it with no slope (in which case I might as well do a simple sweep) or with a 10cm difference, and I need to have a 6cm difference.
