Isolate mechanical, HVAC, and duct line groups from vector architectural PDFs. Inspect by CAD layer, color, or line weight — you decide what to export as SVG or DXF. No upload, no AI auto-detection.
Step-by-step guide to get the most from this tool
Use a CAD/BIM export (not a scan). The tool checks for vector paths before processing.
Toggle groups on the dimmed plan preview. “Possible HVAC” badges are naming hints only.
Download SVG or DXF with original scale preserved for overlay in other software.
What makes this tool stand out
OCG layers, stroke colors, and line weights — you choose what is HVAC.
Dimmed plan with highlighted groups before you export.
Preserve scale for overlay in Illustrator, Figma, or CAD tools.
No upload — floor plans stay on your device.

Quick answers to common questions
No. This tool only works on vector PDFs exported from CAD/BIM software. Scanned or rasterized floor plans have no separable path data, and the tool will detect that and stop rather than producing garbage output.
No. It surfaces the PDF’s existing layers (OCG), stroke colors, and line weights so you can inspect and select groups yourself. “Possible HVAC” badges are name-pattern hints only — not automatic identification.
SVG (primary) and DXF (CAD interchange). You can export the current page, a ZIP of per-page files, or a single stacked multi-page file.
Only if the source file has vector content with distinguishable layers, colors, or line weights separating systems. If everything is drawn in one style with no layers, meaningful isolation is not possible.
No. Parsing, grouping, and export all happen in your browser. The file is not sent to our servers.
Processing runs in your browser. Your inputs are not sent to our servers.
This tool helps you isolate specific line groups — such as mechanical/HVAC layers — from vector-based architectural PDFs. It surfaces the PDF's existing layers, colors, and line styles for you to inspect and select. It does not use AI to identify what ductwork is; you make that determination based on the groupings shown. Works only with vector PDFs exported from CAD/BIM software — not scanned drawings.
Your floor plan is processed entirely in your browser. It is never uploaded anywhere.
