Thank you all for the answers. After many tries according to the given responses i was able to recreate transition shape in Inventor. Now i have used Loft function instead of Patch. After that Cura had not complained anymore and seems that sliced shape now is OK. I have tried to use Loft function before but previously it did not worked. Then using the trial method i have created two lofts -one for inside and other for the outside, generating surfaces, not one solid block. Somehow inventor filled the space between those to surfaces.

This is strange, because Inventor shows decent thickness of transition shape (in light yellow color).

Hello, i have tried to model plastic bottle like those which are sold in stores for drinking water. Bottle generally is modeled from three shapes: almost square body with vertical rounded corners (1); the top ring of the bottle with threads for the cap (2); transition from the main square body to the top ring (3). I have modeled the bottle with Autodesk Inventor, then converted the model to the STL file and imported it to Cura. Cura threw a warning after slicing that "Your model has missing or extraneous surfaces". Next the problem appeared that Cura sliced the "transition" part (3) and converted it to solid block where i need only the bottle wall to be printed. The other two shapes were sliced properly. Then i have tried to convert model to OBJ file, but sliced Gcode file also had the same problem. I have checked STL file in Windows 3D Viewer, the file was OK - i could clearly see that transition area is not filled. So this is the Cura problem. I am attaching STL and Gcode files, maybe someone will be able to help. Never had similar problem before. When i send an STL file to Cura then bottle is Bottle.gcode Bottle.stl
