Hi Booleano, is it that you want those styles to be the default ones when you first launch MOI or do a File > New ?

If so then set up the styles how you want them and then save that to a .3dm file and then put in that file as the template file in Options > General > "Template file:"

When a template file is set, the default styles will come from that file when you start up MOI or do a File > New.
