Professional drawing analysis
for planning applications

Dimension extraction

Precise millimetre measurements from every drawing sheet. Every annotated dimension is captured and cross-referenced across the set.

GPDO compliance matrix

Condition-by-condition check against GPDO Schedule 2 Part 1. Each limit is tested against extracted dimensions with clear pass/fail/unknown status.

Cross-sheet verification

Flags inconsistencies between drawings — e.g. floor plan depth that doesn't match the rear elevation. Catches errors before submission.
