Hi telnoi,

>>i'm trying, but I can hardly rotate the model when stuff hasn't even been joined yet :

There can be slowdowns due to graphics card, make sure you have the latest graphic drivers. You can also help with display speed by changing the settings in MoI: Options~ View~ Mesh Angle: increase for better performance (try 15 or 20), you can also disable the "Add detail to inflections".
