Pick the workspace for the task in front of you. Everything you enter flows through the shared design, the sizing, the takeoff and the live PDF.
Upload your section-detail sheets (PDF, DXF or DWG). Crop each bedroom/config variant once and tag it — the app pre-fills tags from the file name and any embedded sheet text (many CAD PDFs are outlined with no text, so just set the tags by hand — it's quick). To put a drawing on your plan: press ⤵ To PDF on any library item below — it jumps to the PDF tab and drops the detail on the sheet (drag to position, corner to resize, ✏️ to edit values). Or on the PDF tab, + CAD Detail suggests the best-matching variant for the job.
