As a fairly new user to MoI, I've been using it exclusively on Packaging Design projects, forcing myself to figure things out. I've come up against an issue that I just can't figure out. I'm working on a clamshell design that an interesting, very curvy shape on the front. I can't get MoI to apply any fillets to a couple of edges, where I need to have some draft applied. I thought that the shape may be too complex for the fillet function, so I tried creating the bevel and sweeping it around the shape, which worked, but now I can't planar the surface to close the cavity. I think it's totally possible that I've gone about creating this in a less than ideal way in MoI, so I'm wondering if anyone has any ideas for me. It doesn't seem like it should be giving me so much grief, but I can't figure it out. The highlighted lines in the images are the areas in question. The model is also attached.

Thanks in advance for any suggestions.
