You can use the Attribute Manager to create a
.aat file which contains the fills (as well as other attributes, which you want to eliminate for clarity). The other user would then open this .aat file with Attribute Manager to import these fills into their ArchiCAD file.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
