Open DWG and DXF sheets on your phone or tablet — fully offline. Mark issues where they are, compare two sheets side by side and send a PDF or Excel report before you leave the site.
Mechanical, electrical and civil site engineers, inspectors, consultants and subcontractors — everything works on the device, even without a signal.
AutoCAD 2000–2018 DWG and DXF open directly on the phone. Layers, zoom, fit to screen, light or dark background.
Compare revisions or disciplines — architecture next to mechanical, Rev. A next to Rev. B.
Every mark with its photo, status, location and a summary table — ready to send.
Status, discipline, category, NCR / CPR / Punch, room, level and photos — on the exact spot of the drawing.
Line, arrow, circle, revision cloud, text and dimension. Save it all back to a DWG copy.
Live distances and a scale bar, in metric or feet-inches — set automatically by your region.
Tap the drawing, draw a box around the problem, add a photo and pick a status. Last choices are remembered, so the next mark takes seconds.
One tap turns your marks into a report with the project details, a summary by discipline and every issue with its photo and location on the sheet.
All markup tools are free: line, polyline, arrow, circle, revision cloud, text and dimension. The new “Add text” button sits right on the toolbar. Save your markup into a DWG copy — the original file is never changed.
The viewer and markup tools are free. Pro adds site marking, reports and two sheets — with no ads.
