Hi, Drifter,
yes, the dots at the corners also extrude with the square they are part of, as it is a single shape. You normally only need two opposite corners, rather than four, and when you want these sizing pixels, it is better to have all objects in the image use them, and to make them far enough beyond the actual boundary of the largest object, so that you can crop them from the final image in XaraXtreme without touching the main image.
Sometimes it is possible to use other objects as the outer boundary, when those parts have larger extrusions. A good example was my spinning engine from a few years ago. There are four parts, including the main body. The main body has a deeper extrusion than any of the other parts, so all the other parts can be added to it, and the added body will be invisible, buried inside the deep one.
