Hi Michael

Thank you Michael for your feedback.I tried to render with Simlab Composer,but some faces are missing when exporting it in to obj file.I tried also to upload it to sketchfab and it shows me the same problem.When exported to fbx it looks better,but also there are some normal errors.Below are some of my attachments with 3dm zip file.I have only problems above my passenger windows.For creating windows I made closed profiles and created cuts with trim tool.Then I pulled my windows inside and connected with blend tool.Doors were created also with trim tool,but then I jointed with fuselage and created insets with inset tool.Maybe I do something wrong,or polygonal exporters can't handle this model.Other parts looks great.Thanx in advance for your advice.

Regards from Nikola
