https://youtu.be/TcfdVmU30Hk This a model of hepatic lobule depicting the structure of the blood vessels and bile duct along with the flow of fluid within a lobule. The structure has been labelled with texts on the view port itself. The materials are based on cycles render. I have used the array modifier, curve modifier along with empties to design the structures. In the .blend file most of the modifiers have not been applied to leave space for further modification by the designers downloading the model. Rest of the extensions (OBJ,FBX,3DS, DAE) have been exported from blender after applying modifiers The blend file has 2 layers First layer :- a complete lobule Second layer :- 1/6 part of a lobule The short forms in outliner stand for:- BC :- Bezeir curve Cyto :- mesh/ material of cytoplasm Nuc:- mesh/ material of nucleus The formats 3mf, obj, fbx, USDZ,GLTZ & GLB with applied uv mapped textures have also been included in the downloads along with stl.
