Formerly OhmGrid: same app, new name.
What it does today
- Counts symbols from the drawing itself. Ferrule matches the drawing's own vector linework, not an AI's guess, so the same drawing gives the same count every time. Every count is a mark you can click and check. On a real A1 power plan with 107,000 paths it found 96 outlets, no false positives, in under a second.
- Your decisions stay put. Running detection again never overwrites what you've confirmed. Where it disagrees with you, it flags it and you decide.
- Marked-up check set. Exports a PDF with the marks stamped on the original drawing, a key on each sheet, and the drawing's fingerprint, so the check set shows which revision it belongs to.
- Cable measured per circuit. A factored straight line, snapped to a traced tray or catenary, or a route you draw, with drops and tails added. A check flags Cat6 runs over the 90 m channel limit.
- Priced the way you'd price it. Assemblies keep materials and labour hours separate, and markup, overhead and margin are kept apart too. You get a priced BOM, a CSV export, and a request-for-quote export to send to your wholesaler.
Not built yet
These are planned, and none of them exist today:
- Reading wholesaler quotes back into a job.
- A company price library.
- Revision change lists, showing what changed between drawing issues.
Good to know
- Windows desktop app. Works offline, on your own machine.
- Your data stays yours. Drawings and pricing aren't uploaded anywhere.
