Filling a large space with identical blocks from accurate CAD model

I've got an accurate model that I've created, i.e. 0.5 cm x 0.5 cm x 0.5 cm. This accurate model is just a sub-component of a much bigger model.

The entire model would be about 500 cm x 500 cm x 500 cm. Furthermore, it's made up of identical blocks (the accurate model I made) filling the entire space.

Is there a way to "fill" the bigger geometry with my much smaller accurate model? I think it would take me a life time to completely fill the entire cube with the smaller module. 


Kind Regards

If you're in SpaceClaim use the Move tool and look in the options (panel lower left side of the screen when Move is active) for Pattern. You may need 3 patterns to create the shape. Depending on how complex the model is this may also mean that you exceed the number of faces available in the Student build.

If you use DesignModeler, here is a recent post with the Pattern example. You will need two patterns to make 3 dimensions.

As rwoolhou says, you can't put 1,000 x 1,000 x 1,000 = 1 Billion copies of something on the Student license. I don't think you can to do that on an unlimited license because it is too much geometry and it will never mesh.

This is where Engineers abstract the small features away and make a single solid to represent the behavior of the tiny cells. I modeled a honeycomb core sandwich panel.  I didn't model all the little walls and hexagonal air spaces, I just used one rectangular solid and applied Orthotropic properties which made that solid behave like a honeycomb core.
