CAD · DWG
Native DWG drawings
Review supported CAD geometry, layouts, blocks, text, hatches, and layers without first converting the source drawing.
Review every plan from CAD to PDF
One plan-review workspace
CAD is the domain. DWG and PDF are the plans you receive.
PlanInspect does not flatten every format into the same promise. It keeps the useful structure of supported DWG drawings and gives issued PDF plan sets a calibrated, page-aware review workflow.
Multipage PDF plans
Browse page sets, calibrate a known dimension or effective print scale, measure, annotate, and snap to supported vector paths.
PLAN REVIEW
One field workflow
Keep measurements, notes, photos, markups, annotation layers, and exports with the plan across iPhone, iPad, and Mac.
Now available on Mac
Take DWG and PDF plan review from the field to your Mac
Open local DWG drawings and multipage PDF plans from Finder, measure, annotate, and export without a required cloud upload.

The Problem
Project plans should work wherever the work happens
Construction teams receive both CAD drawings and PDF plan sets. They need one focused tool to review either format on site, without a desktop or required upload.
No internet on site
Cloud-based viewers are useless in basements, remote sites, or areas with poor connectivity.
A split DWG and PDF workflow
Switching apps breaks the review trail. Keep the original DWG structure when available and work directly on issued PDF plan sets when that is what the team receives.
Chained to a laptop
AutoCAD and desktop viewers aren't practical when you're walking a job site with dirty gloves.
The Solution
Your drawings. Your device. Zero dependencies.
PlanInspect reads DWG drawings natively and opens multipage PDF plan sets on iPhone, iPad, and Mac. No required upload, third-party conversion, or account.
100% on-device
All processing happens locally. Manually back up and restore via iCloud when you need to.
Instant rendering
Native Metal rendering for silky smooth pan, zoom, and interaction.
Format-aware plan review
Use DWG layouts and layers when the CAD source is available. For PDF plans, browse pages, calibrate scale, and snap to supported vector geometry.
Privacy first
No third-party accounts, no data collection, no analytics on your files.
