I'm confused after trying to create a 3D model in 3D modelers like Blender. I created a 3D box that is one unit long, high, and wide. I exported the box to 3DS file. I imported the box into MED. I saved the box to MDL file. I placed the box in WED but the box is too small. I had to scale the box to fit the small grid square which is 16 units long, high, and wide. The grid doesn't show in MED. How do I enable the grid in MED? How to I convert the 3D model to 3D triangle mesh in Blender before exporting the 3D model?

The size of 1 blender unit may not represent 1 quant (the measure used in the engine), so naturally it will not be the same scale
