Importing objects from 3D Studio Max

[Phil_C]

Hello All
I have been using Chief since version X2 and now I have decided to make some of my own objects. I am very experienced with 3d Studio Max and much prefer to use it over Sketchup. The problem is I cannot get an object from Max into Chief correctly. I tried exporting from Max in DXF and 3DS but when the item is imported into Chief they end up without any textures and 1mm cubed in size. Obviously I must have a setting wrong somewhere but I don't know what. I also tried importing some Sketchup models and while the textures showed up the model was tiny. Chief is set up for Metric measurement as is Max.
Max version is 2011 and I am using the X5 Beta in both 32bit and 64bit.

Any help would be greatly appreciated.

Regards

Phil
