How to split .obj file into separate tiles?

[Anonymous]

I have been looking at several programs to check how to do this, such as Meshlab and Blender. So far I have had no luck figuring out how to cut the object into equal parts Is there a way to cut a huge .obj file into tiles (which can then be exported separately)? I am looking to cut this object into 12 or 20 tiles (3x4 or 4x5). These tiles should overlap somewhat so that we can easily see where they join with other tiles. An example of how this .obj file would look is attached

Basically EDIT/PlaneCut should be the tool you're looking for.

For easier cutting I recommend to have the object perpendicular to the base grid for PlaneCut always starts with a horizontal cutting plane . You may rotate it using EDIT/Transform.

I also recommend to center the object at the origin. You can do this via EDIT/Align (Source = CenterPoint, Destination = WorlOrigin/Y-up). This alignment will allow easier calculation in PlaneCut.

To cut an object through its middle run PlaneCut at its CutType = Slice(KeepBoth). Accepting the tool you will not see any changes for the halves fit perfectly. Run EDIT/SeparateShells to split the two halves to different objects.

To get accurate distances of the different cuts enable snapping. Snapping is enabled if the S circle at 8°clock in the widget is green. If not click it. When activated and you drag an arrow in the widget the cutting plane snaps to certain increments. While visible the increments can be controlled by the up and down arrows on your keyboard. 

I'm not sure what you mean by "overlap somewhat". Something like a registration dowel or a rabbet joint?
