Multiresolution modifier blender 2.67

Hello,

When i start with a cube and use multiresolution modifier and choose subdivide the cube is becoming a ball? Can it be made back to a cube? Or do i have to use another way?

Thx kind regards,

Rob

Choose simple subdivision instead of catmull clark, and then the cube should retain its original form

Ok thx I found the solution under Meshtools in edit mode
