Hi there
Is this pertaining to any c# code or functionality you have written, or this a general Autocad error? if the former please provide more details of what's going on: your code and what you are trying to do. if the latter why not try another forum where folks would better be able to help you? in any case you must specify more than "i have an error" - otherwise nobody will be able to assist you. hope this helps
best rgds
Ben
