BTW...the dimensions on the survey drawing you attached to your other post (i.e. - plot plan) are in decimal feet and inches.  So, for example, the distance shown as 12.7' (twelve point seven feet) is equivalent to 12 feet 9 inches.  

Thanks

We need to know the scope of the project.  You need to be more forthcoming about your "project".

The engineer (civil, structural, electrical, mechanical, etc.) or architect is responsible for coming up with the general notes where applicable to their field of expertise.

Who are you doing the drawings for?  Personal use?  A client?  The company you work?

where to get that General Notes text? and how we I know that is the correct notes?

An architectural floor plan doesn't normally have general notes as most features are labeled.  Depending on how thorough you want to be you might include both a window and door schedule if it was new construction or a renovation.  Once again the owner's name and address, the date, scale, and the initials of the person who drew the floor plan should appear on the drawing.  General notes usually appear on foundation plans, roof plans, electrical layouts, plumbing layouts and building cross-sections. 

Visit you local library and find a book about architectural drafting and design.  There will be plenty of examples to follow in the book.

Thanks

Where in the United States are you located?

BTW...floor plans are not shown on plot plans.  A plot plan is supposed to show features like a house, garage, shed, swimming pool, trees, fence, driveway, etc. relative to the boundary of a property.  Plot plans are considered civil drawings.  Floor plans on the other hand are architectural drawings showing the physical layout of a house including walls, stairs, room layouts, closets, utility rooms, bedrooms, bathrooms, kitchens, dining spaces, etc.  Do you get the distinction between the two types of drawings?
