As there are not very many X3D Maker tutorials at all most peeps have to learn as they go. But personally although I really do enjoy the prog I just dont find enough time with all the other software I use to progress with it very fast.
I find with most graphics softwares theres tutorials of all levels made by the manufacturer but more importantly by peeps who use it.
Ive seen some great little animations simple or not and can sometimes figure out how theyre done - Mixing X3DM7 with photoshop.
BUT it would be excellent if members shared more of their knowledge with us peeps who unfortunately dont have the time to learn as fast as we want
