Floor plan digitization<\/strong> converts a physical drawing \u2014 paper, scan, or photograph \u2014 into a professional digital file that engineers and architects can work with directly. For older properties with paper-only documentation, this conversion is often the fastest and most affordable way to start a construction or renovation project.<\/p>\n This case study describes a real project where an old paper floor plan was converted into a DWG file for a heating system design.<\/p>\n Key Facts<\/strong> The client was a property owner planning a complete heating system upgrade for a mid-century apartment. A proper heating system design requires an accurate floor plan. The engineer needs room sizes, wall positions, and door and window locations to calculate heat loads, pipe routes, and radiator placements.<\/p>\n The property had an original floor plan from the 1970s. It was a pencil drawing on large-format paper, partially faded, with some dimensions worn away. It had never been digitized.<\/p>\n The heating engineer could not use it directly. He needed a DWG file \u2014 a format he could open in AutoCAD, overlay his pipe routing design on, and submit as part of the project documentation.<\/p>\n The client photographed the original drawing under good lighting. A phone camera was sufficient. He uploaded it to Replanera along with a few confirmed measurements for the sections where the original was unclear.<\/p>\n We reviewed the uploaded photo and identified two areas where dimensions had worn away. A short email exchange with the client confirmed those measurements. No site visit was needed. The client measured those two walls with a tape measure during a normal visit to the property.<\/p>\n We rebuilt the floor plan from scratch in CAD software. The original paper plan served as the structural reference. The confirmed dimensions served as the source of all measurements. This is not a tracing process \u2014 it is a professional redraw that produces a clean, accurate, editable file.<\/p>\n The finished floor plan was delivered in three formats:<\/p>\n Turnaround: 2 business days from the time confirmed measurements arrived.<\/p>\n The heating engineer received a DWG file he could work with immediately. He overlaid the pipe routing design on the floor plan, adjusted for the actual room dimensions, and submitted the complete documentation to the building authority.<\/p>\n Without the digital floor plan, the project would have needed either:<\/p>\n Neither happened. The digitization cost a fraction of either alternative and took less time than survey scheduling alone.<\/p>\n

– A DWG file<\/strong> is a vector-based CAD format used by AutoCAD and similar engineering software \u2014 it can be edited, scaled, and layered with technical designs
– 80% of architects now use design software for their projects (OpenAsset, 2024<\/a>)
– Hiring an architect to survey and redraw a floor plan costs $2,000\u2013$20,000 in the US, or EUR 80\u2013100\/hour in Western Europe (HomeGuide, 2026<\/a>)
– Over 80% of top municipalities require digital permit submissions (ScienceDirect, 2022<\/a>)
– Replanera delivered this project in 2 business days \u2014 DWG, PDF, and PNG included in one fixed price<\/p>\n<\/blockquote>\n
