I build a building use MOI, and Export 3DS to 3DMAX, but there is someting wrong with my four viewports : I can't see any edges, and can't select them in top front and side viewports---


Then I export OBJ to 3DMAX, and luckily I can see the edges but the faces are all damaged--






then I use Silo open the OBJ file expored from MOI and then save as 3DS then import to MAX and it turns OK,

AND OBJ FILES TO MAYA IS OK
