Uploading Blueprints and Floor Plans

FieldMarkup accepts three file types:

• PDF: the standard. Architectural drawings, GC plan sets, anything exported from CAD.
• JPEG / JPG: phone photos, scanned plans, satellite screenshots.
• PNG: same as JPEG, just a different image format.

Images (JPEG and PNG) are automatically converted to a single-page PDF when you upload. The editor always works with PDFs internally, so everything behaves the same regardless of what you started with.

CAD files (.dwg / .dxf)? FieldMarkup doesn't open CAD files directly. Open the drawing in your CAD tool (AutoCAD, Autodesk TrueView, or the free LibreCAD), go to File → Plot → PDF, then upload the resulting PDF.

On the project page you'll see three buttons for floor plans:

1. Upload Floorplan: opens your device's file picker. On iPad this shows Files, Photo Library, and the camera. On desktop it opens the standard file dialog. Use this for PDFs from email or cloud storage, satellite screenshots, or any file already on your device.
2. Take Picture: opens the camera directly. This is the field workflow: you're standing in front of a paper blueprint on the job site wall and need to snap it. The photo gets converted to PDF automatically.
3. Blank Canvas: skips the upload entirely and creates an empty 11x17 landscape page. Useful for residential sales walkthroughs where you're sketching coverage from scratch.

On desktop, you can also drag and drop a file into the drop zone below the buttons.

The uploader has a toggle at the top: Floor plan and Document.

• Floor plan: opens in the editor for markup. This is where you place devices, draw shapes, and annotate.
• Document: stored as a reference file (download only). Use this for cut sheets, spec sheets, contracts, or any file you want attached to the project but don't need to mark up.

The maximum file size is 25 MB per upload. This covers virtually all architectural PDFs and phone photos. If your file is larger, try reducing the PDF quality in your CAD export settings or using a lower camera resolution.

Phone photos are automatically scaled so the longer side is capped at 2,400 points, which keeps the editor responsive even with high-megapixel camera shots.

Multi-page PDFs are fully supported. When you upload a plan set with multiple pages (floors), the editor shows page navigation at the bottom so you can switch between pages. Each page gets its own set of annotations. Devices placed on Floor 1 don't appear on Floor 2.

The exported PDF preserves all pages with their respective annotations baked in.

• Paper plans: Lay the plan flat, get directly above it, make sure there's good lighting. Avoid shooting at an angle. Perspective distortion makes devices look misplaced.
• GC plan sets: Ask for the electronic PDF, not a scanned copy. Electronic PDFs are crisper and smaller.
• Satellite images: Take a screenshot from Google Maps or Google Earth, save as PNG or JPEG, and upload via the Upload Floorplan button.
