I've got a model I've exported from Fusion360 and imported into Cura to slice. When I look at it in Prepare or XRAY it shows it's a solid part (as designed) but when I look at the layer view Layer 186 of 381 is suddenly at Z=0 instead of between 186 and 187. I haven't tried to print it yet, but I'm worried to try as I don't want to shove my nozzle into the print. It feels like a bug, but it could easily be user error as I'm a novice with this software. Haven't found any related topics yet, so if I just can't find the right search terms please point me that way if there's already a thread. Thanks
