Is it possible to make 3D model

Actually I’m new to Unity… and I’m beginner for game making too… I want to know is’t possible to make a 3D model using Unity?? without importing…
Please help me…

No, it’s not. Unity isn’t a 3d modelling package- it’s a game engine and a level editor for said game engine. Have a look at Blender if you want a free, high-end 3d modelling package to work in.

A better question would be- why do you want to? Unity is perfectly good at what it does, but creating 3d models from scratch is not that. It is possible to write programs which would have that functionality in Unity, but honestly you’d be much better served to just use existing packages which will be much better optimised for that kind of work anyway.

Incorrect or some what. Technically any programming software can 3d model its just code base and not recommended. unity isn’t made for 3d modeling but with code you could add your own editor for 3d modeling.
