From PDF to BOM in 15 minutes: a takeoff walkthrough

A narrated walkthrough using a real one-line diagram. Scale calibration, templates, counts, grouping, totals — start to finish.

Placeholder body — to be written. Outline below.

What you’ll need

  • A PDF of a one-line diagram (we’ll use a real one).
  • Five minutes to set up the templates.
  • Ten minutes to do the actual takeoff.

Step 1 — Upload and calibrate scale

Drag a PDF in. Click two points on a known dimension, type the dimension. Done.

Step 2 — Set up your templates

For this walkthrough: a Receptacle template (type, voltage, circuit), a Lighting fixture template (same shape), and a Conduit run template (size, type). Show the property panel as we build each one.

Step 3 — Click and measure

Run through the actual takeoff. Show the totals panel updating in real time. Highlight the property-based grouping kicking in as we annotate fixtures of different types.

Step 4 — Read the BOM

Open the totals view. Group by template, then by property. Copy out the breakdown. Paste it into your estimating spreadsheet.

Replace this placeholder with the real walkthrough — ideally with embedded screenshots or a short video — when the supporting material is ready.
