Commercial homerun planning

Turn plan PDFs into pull-ready homerun layouts.

Import the sheet, sketch the route, assign circuits, and catch expensive mistakes before material gets ordered.

That's ZapSketch.
Real plan context, not another disconnected calculator.

Use it when you need fast preliminary numbers, cleaner field handoff, and fewer material surprises.

The real cost of guessing

Small homerun mistakes turn into real material money.

$1,046

The over-ordered wire package

A 200-circuit job only needs a few feet of padding per run before the copper waste becomes a four-figure line item.

$780

The oversized conduit habit

When nobody checks fill until late, crews tend to size up. That extra EMT adds up fast across long commercial corridors.

$2,100

The re-pull nobody planned for

A circuit assigned to the wrong route can mean wasted wire, schedule friction, and overtime nobody priced into the job.

How it works

From floor plan to field-ready output.

1

Import your PDF

Drop in a floor plan and calibrate the scale. ZapSketch overlays a working electrical layer on the real drawing.

2

Sketch homerun routes

Place panels, junction boxes, and endpoints. Draw raceway paths while route lengths stay visible.

3

Check and export

Review preliminary sizing, voltage drop, conduit fill, and EGC notes. Export marked-up plans for the field.

What you get

Built for commercial homerun planning.

Plan PDF markup

Import floor plans and draw panels, junctions, endpoints, and raceways directly over the sheet.

Real route measurement

Calibrated scale means raceway lengths reflect the actual drawing instead of a rough takeoff guess.

Circuit scheduling

Build panel schedules, assign circuits to endpoints, and keep route ownership visible in one view.

Pull schedule output

Export labeled route summaries with lengths, conductors, conduit, and preliminary checks.

Preliminary calculations

Check conductor sizing, AC/DC voltage drop, raceway fill, and EGC requirements as you sketch.

Clean field handoff

Create marked-up plans and schedules the crew can read without hunting through notes and spreadsheets.

Simple pricing

One avoided mistake can pay for a year.

What teams are saying

Built with electricians, for electricians.

"We used to guess at homerun lengths and always over-ordered wire. Last month ZapSketch saved us about $800 on one job alone."
MC Mike C.Estimator, mid-size commercial contractor
"The foreman loved having a marked-up plan instead of my chicken scratches. Handoff was way cleaner."
JR James R.Project manager, electrical subcontractor
"I switched from a spreadsheet and a PDF viewer to ZapSketch. Same data, one view, fraction of the time."
KL Karen L.Lead estimator, design-build firm
