“I use PlanSnapper every day to measure finished basements for ANSI requirements. It saves me at least 30 minutes a report.”

Common workflows
Both produce accurate, to-scale floor plans but intentionally omit square footage. Upload the export, set one wall length, done.
Trace above-grade area with one polygon, below-grade with a second. PlanSnapper keeps the totals separate and ANSI-compliant.
Run the tool on your CubiCasa or Matterport plan and compare against your sketch. Catch dimension errors before they hit the report.
Run the floor plan yourself before the report. Catches honest mistakes and not-so-honest ones before they become liability issues.
Measure from the office when a field visit is not possible or not billable. Any to-scale floor plan in your inbox is enough.
Add a second polygon to exclude attached garages, covered porches, or any non-GLA area. The math comes out right automatically.
How it works
Export from CubiCasa, Matterport, or iGUIDE as PNG or PDF. Screenshot from the MLS. Photograph a printed plan. Any to-scale image works.
Click two points on any wall you know the length of — a room dimension, a lot line, anything. PlanSnapper calibrates every other measurement from there.
Total GLA, perimeter, and individual wall lengths in feet and inches. Add a second polygon for basement or garage exclusions. Export the result.
