I have what I think is a strange problem creating polygons with extended types (I am compiling .mp files). Through much debugging I discovered that if I set my custom polygon type code to 0x10100…0x10105 they display correctly but any type > 0x10105 does not display in basecamp or the device. I have seen example TYP files that have many polygons with types > 10105 so presumably, these are value codes. Can anyone suggest what might be wrong and, ideally, point me to some documentation that would explain this behavior.
Thanks.
