Tape shift + z, for zoom extents.

After you use the instruction given by Box, you can try this procedure to make sure that you dont have stray geometry very far from the model:

1 - Select All.

2 - Press the SHIFT Key down and keep it pressed to Add/Subtract from the selection.

3 - While still pressing the Shift Key, do a window select to deselect the model.

4 - Press the Delete Key.

You can also bring the model closer to the axes origin if you don’t need it to be located about 143 meters from the origin.

It worked! thank you for this tip, it helped a lot.
