How to change geometry into block in 3DEC v5.2?

Hi, I can import the geometry of the model i.e. stl file. But How to convert this geometry into a block model?
I have seen that this can be done in 3DECv7. But would this be possible in v5.2?

To my knowledge this is not possible in 3DEC5.2, at least not with the on-board tools.
You can however write a conversion program in whatever programming language you are familiar with that creates the corresponding poly face-commands for the block.
But note, that this only works if the volume of your stl.-file is convex.
