Moving through the grid

There are several ways to change what you can view of the grid. You can use the thumbwheels in the lower left corner to spin around the model. You can also use the thumbwheel in the lower right corner to zoom in and out.

Lastly, you can move the grid vertically and horizontally by using the sets in the lower middle part of the window.

Adding a Lego block type

Check out the existing types in the "blocks" directory. The definitions for the polygons are the same as for OpenGL. The top tag specifies that a top should be put on the top of a part of a block. The rest should be self-explanatory.

Problems

The new grid option does not empty the current grid. This is regarded as a feature. For now there is no other solution than to restart the application or empty the grid by hand
