There are multiple methods for aligning models to the grid. The following will show a simple method followed by a more complicated one.

1) Simple Alignment

Often, an object out of alignment can be corrected by opening the „item“ tab on the right-side panel, and looking for the rotation values. We can see here that the values on all three axis are rotated, these can be „zeroed out“. Simply select the value to be changed and type 0.

2) Complex Alignment

If we look at the rotation values of this cube, we can see that it shows 0 for all axis. This means we need a way finding those values, in order to return it back to the original rotation.
