Hi Pilou, most STEP files don't have any color information in them. There are 2 different varieties of STEP file: AP 203 and AP 214. The AP 203 variation doesn't have any mechanism in it to transfer color information (if I remember correctly), and that's what format your particular STEP file is using.
If there is a way to set SolveSpace to write out AP 214 type STEP files, maybe that will work, but I'm not quite sure if the STEP import library that MOI uses picks up those attributes in AP 214 type files or not. The AP 203 type file (with no color support) tends to be the most often used I think.
I tested your same STEP file going into Rhino and ViaCAD and only default colors are shown in those programs as well.
So I believe that's just a common limitation with STEP format in general.
