Can someone help me I recently had to locate an old plan and move to v20. Only problem is the old plan was created with multi drawings and once I moved to v20 I cannot remove the multi drawings. Is there a simple fix to this?
I would just sent to tech support. If it can be done, they should know now or have all the past versions. Hopefully you kept a native V12 copy as they are not back compatible once converted to a later version.
