Hi Mikhail, the hidden line drawing generation was a new feature added in to MoI v3. Above you write that you got the drawing on the left using MoI v1 or MoI v2, but that is not possible. Before MoI v3 the AI export only had a basic wireframe only export, the extended option and hidden line/shaded drawing generation is new for v3.

The V3 beta period is long since over, and V3 betas are incomplete versions of v3 without all the final features. Also the official v3 beta versions have long since expired and the only way to run them is by running a cracked pirated version. If you are running a pirated version please do not post support questions on the official forum.
