Troubleshooting

Ordered roughly by how often they come up.

The boundary has a gap and the fill escaped through it.

Lowering Color Tolerance usually will not help, because the cause is a genuine opening rather than a colour difference. Close the gap with Manual Border (B), then fill again. See Manual borders.

If the drawing is a floor plan and the fill ran through doorways, use Door-aware Fill from the canvas controls instead of bordering every opening.

Still escaping after one border? There is a second gap. Follow the edge of the runaway fill and you will find where it got out.

The fill picked up more than I wanted, but stayed contained

Section titled “The fill picked up more than I wanted, but stayed contained”

Lower Color Tolerance in Region Settings and click again. Work in small steps, since a large jump usually trades one problem for the other.

If the two materials are genuinely almost the same colour, switch to Precision Region (P) rather than continuing to fight the tolerance.

Raise Color Tolerance. Hatched and textured areas usually need more than flat filled ones, because the hatch introduces variation the tool would otherwise read as a boundary.

The fill left a thin fringe around the edge

Section titled “The fill left a thin fringe around the edge”

Use the eraser’s Boundary and Cutouts adjustment to tidy the edge rather than erasing and refilling.

The drawing scale is wrong. This is by far the most common cause of wrong numbers, and it is the first thing to check whenever quantities look off.

Recalibrate against a known dimension, then verify against a second one at the other end of the sheet. See Setting the drawing scale.

Something is hidden. A hidden group is excluded from totals as well as from the view, and so is a hidden item inside a group.

Unhide everything and check the total again. This is also the most common reason an export comes out short.

Look for work counted twice:

  • A duplicated region left on top of its original counts twice, which is intended behaviour since a copy is treated as a second real item.
  • A linear run traced twice, usually where a trace was restarted partway. The layer panel shows one row per run, so a group with more rows than you expect is worth opening.
  • In counting, one symbol matched twice by Auto Count. Raise Duplicate Distance and run it again.

Quantities recalculate as you work. If a number looks stale, check you are reading the group you actually changed, and that no filter or hidden state is affecting what you are looking at.

Zone totals do not add up to the sheet total

Section titled “Zone totals do not add up to the sheet total”

Check whether zones overlap. Shared ground is counted once and attributed to the zone drawn first, which is deliberate so that zone totals cannot exceed the sheet. Also check whether some takeoff sits outside every zone.

Large sheets take longest on first open and are quicker afterwards. Lowering drawing quality helps if you do not need fine detail to click accurately.

Hiding groups you are not working on also helps on a dense drawing.

The drawing looks soft or the text is hard to read

Section titled “The drawing looks soft or the text is hard to read”

Turn on Crisp from the canvas controls. If materials are hard to tell apart, try Hueprint.

A control says “Not available for this drawing”

Section titled “A control says “Not available for this drawing””

That feature does not apply to this sheet. It is not an error.

The drawing scale is not set. You will see a message saying so. Set the scale first, since a measurement without one has no meaning.

The engine that performs measurement work stopped unexpectedly. PixelTakeoff tries to restart it automatically, and in most cases a message that it is recovering is followed shortly by one saying it is back. Retry whatever you were doing.

If the message says it is offline and asks you to restart, close and reopen PixelTakeoff. Your saved work is unaffected. If it keeps happening, send a support bundle.

Windows shows “Windows protected your PC” for software from a new publisher. Click More info, then Run anyway. Your IT team can verify the file against the SHA-256 checksum supplied with your download.

Check the key was pasted in full with no trailing space. A license is tied to one machine, so if you have changed computers, contact support to release the seat.

If something is not behaving as documented, go to Settings → Advanced → Export Support Bundle.

That produces a single file of diagnostic logs. It does not contain your drawings or your takeoff. Send it to support with a short note about what you were doing and what you expected, and it usually identifies the cause straight away.

The most useful note is a specific one. “Area stopped changing after I erased twice on the paving group” is far more actionable than “quantities are wrong”.
