How-to guide

How to count symbols on a drawing automatically

Counting every socket, light fitting or manhole on a set of drawings by hand is slow, and it's easy to miss one. Takeoff Studio's Find symbol does the counting for you: box one symbol, check what it finds, and accept. It's part of Takeoff Studio Pro, which has a free first month, and your drawings never leave your PC.

What you need

Step by step

1

Open the drawing and set the scale

Open the drawing with Load PDF and Calibrate the page (R) from a dimension you trust. Find symbol works on calibrated pages, so if you want to search a whole set, calibrate every page you need.

Open the drawing and set the scale - Takeoff Studio
2

Box one symbol

Choose Find on the toolbar (or Find symbol in the command palette, Ctrl+K), then drag a box tightly round one example of the symbol - a socket, a light fitting, a door swing or a manhole. Takeoff Studio searches the page and rings every match. Tick All calibrated pages to search the whole set.

Check the matches

Every match has a ring round it - 218 matches on this furniture plan. Move the Sensitivity slider to see fewer, closer matches or more matches straight away. Click a ring to remove a wrong match, and click it again to put it back. Tick Turned 90°/180°/270° or Mirrored to catch symbols drawn the other way round.

4

Name it and accept

Type a name for the count, such as Stacking chairs or Ceiling light points, and choose Accept all. The matches become one ordinary count markup on each page, so you can add, move or delete points afterwards, and one Undo removes the lot. The count goes into the Totals and the schedule like any other.

Tips

Frequently asked questions

Is Find symbol free?

Find symbol is part of Takeoff Studio Pro (£24.99 a month or £199.99 a year, first month free). Measuring, including counting by hand with the Count tool, is free in Takeoff Studio.

Can it count across a whole set of drawings?

Yes. Tick All calibrated pages and it searches every page you have calibrated, with one count markup for each page when you accept.

What if it finds something that isn't the symbol?

Click the ring to remove it before you accept, or lower the Sensitivity slider. After you accept, the result is an ordinary count, so you can still delete or move points.

Are my drawings uploaded anywhere?

No. The search runs on your PC. Takeoff Studio is a Windows app and works offline.
