These instructions will help you create clear and accurate floor plans from complicated construction documents. In today’s world the simpler and more concise a drawing or map is, the better and faster a person can use it for its intended purpose. These instructions can help you achieve this given you have a basic understanding of Autodesk Software/vector based computer aided drafting and, specifically, the commands and procedures within AutoCAD.

If unfamiliar with AutoCAD software please refer to  FlowJet Series parts 1 to 6  found on the Instructables website. 

Creating understandable floor plans from an architectural drawing will help you complete a Utah State University standard working single floor plan of a of approximately 10,000 square feet in 1.5 to 3.5 hours depending on your AutoCAD proficiency. The floor plans created may be used to calculate space and direction data for any and all who rely on them. These plans may even be able to provide hours of enjoyment when printed on paper that can be folded into a paper airplane!

Step 1: Preparation

Ensure that the following things are at your disposal:
    AutoCAD software installed
    Architectural CAD file of building you wish to clean up/convert
    Existing standardized floor plan CAD file

Step 2: Open architectural construction drawing

Open CAD file of floor to be standardized. Note how busy the drawing is with all of the included construction details. This process will show you how to cut out the excess that isn't needed in a basic floor plan both efficiently and effectively.

Step 3: Using the FREEZE command

Freeze the layers that are not necessary. This cleans up most unwanted aspects of a floor plan and readies it for transfer. The necessary layers will usually include only the walls, windows, doors, stairs, and room information tag layers.

Step 4: Create a copy

Select and copy all components of drawing to be moved into an existing floor plan file.This should be done one floor of a building at a time to ensure thoroughness in the transfer.
