Version 1.0.0

How many m² of cladding are in this area?

AreaPilot finds the closed areas in your AutoCAD drawing, reads their codes from the text next to them, totals the m² and exports it to Excel.

No more measuring the area of every work item in a building one by one and adding it up on a calculator.

What it does

Selects closed areas

Pick a few areas yourself, or take every area on a layer at once. Areas inside xrefs and blocks are found too.

Reads the code from nearby text

Text inside or next to an area (TEXT, MTEXT, block attributes) becomes that area's code, and areas with the same code are grouped. If an area holds several texts, the Code source setting decides which one is used.

Totals area and perimeter together

For every code the list shows area, perimeter, count and totals. Click a row and those areas light up in the drawing; Click Inside shows area and perimeter under the cursor. Search the list by code, or untick a row to leave it out of the total.

Handles openings and duplicates

In nested areas the inner opening (column, shaft) is subtracted; the same area drawn twice is counted once.

Builds boundaries from open lines

Click inside an area, take every area in a region, or turn the regions closed by the lines you select into boundaries in the drawing. Outline closes small gaps at the corners by extending the lines (arcs along their own direction) and produces one closed boundary.

Writes results to the drawing and to Excel

Area labels and a table go into the drawing; the list and totals are saved as an .xlsx file, or copied as CSV, text or to the clipboard. On the Fabrication tab you can group panels by fabrication date, color them in the drawing and export a separate fabrication list.

The interface is available in 10 languages: English, Türkçe, Deutsch, Français, Español, Italiano, Português, Русский, 日本語, 简体中文.

How it works

1
Install. Run the installer. No administrator rights needed; AutoCAD must be closed.
2
Open. Type AREAPILOT at the AutoCAD command line. The window opens next to your drawing.
3
Select and export. Select the areas; you get the list, the codes and the total m². Write them to the drawing or export to Excel.

Requirements

Windows 10 or 11, 64-bit
AutoCAD 2013-2027, 64-bit
AutoCAD 2013-2020 needs .NET Framework 4.8 (already included in Windows 10 and 11)
Does not work with AutoCAD LT.
Excel does not need to be installed; AreaPilot creates the file itself.

Before you try it, plainly

AreaPilot is used every day on real facade drawings, but that use is in AutoCAD 2021. The add-in is built for AutoCAD 2013-2027; versions other than 2021 have not been tested yet. If you use another version, try it first with the 7-day full trial; telling us whether it works is also very useful.

Trial: 7 days from first launch, all features unlocked. The days left are shown in the top band of the window. When the trial ends the commands stay available and AreaPilot switches to free mode: up to 15 areas are processed per run. Entering a license code removes that limit.
Work on a copy of your drawing. "Delete duplicates (OVERKILL)" and "Purge unused (PURGE)" change the drawing. Both can be undone with _U, but use a copy anyway.
If something goes wrong, AutoCAD keeps running and an error report is saved on your computer. Nothing reaches us unless you send it.

Two warnings you will see during setup

The installer is not digitally signed yet, so Windows and AutoCAD each ask once. Both warnings are expected.

1. Windows: "Windows protected your PC"

Windows stops the installer because it does not recognize the publisher. Click More info → Run anyway. Only download the file from the link we give you on this page; do not run a copy from anywhere else.

2. AutoCAD: "Security – Unsigned Executable File"

The first time you type AREAPILOT, AutoCAD shows this window. Choose Always Load. AutoCAD will not ask again.

Verify your download

The hash of the installer you downloaded must match the one below. In PowerShell: Get-FileHash "AreaPilot-Kurulum.exe" -Algorithm SHA256

Version	Release date	SHA-256
1.0.0	2026-11-07	3719B18C0D7E8B91D8B0029B0C4BD75C41FA93396B286E2861BFCA98A2AE3602

AreaPilot is provided "as is". Check the calculated areas and quantities against your own drawing before you use them; errors may occur. Liability that cannot be limited by law is unaffected.

FAQ

Is AreaPilot paid?

Yes, it is a one-time licensed product. After you download it, all features are free for 7 days from first launch and we do not ask for payment details. When the trial ends AreaPilot does not lock; in free mode it processes up to 15 areas per run. A license removes the limit; prices and terms are in the Pricing section on this page.

Where do my drawings go?

Your drawing never leaves your computer. AreaPilot processes it on your computer; your drawing, your results and your user name are not sent to us, and there is no analytics or usage tracking. To check for a new version it reads the version file on ostlertech.com; no drawing or license information is sent with that request. If you enter a license key it connects to our server: activation sends the license key, a random device number and the application version; and while AreaPilot is running and the computer is online, about once a week it makes a license status check (only the license key and the device number are sent). In the trial and free mode nothing is sent for the license. As with any internet request, our server sees your IP address. If an error occurs, the report is saved on your computer, is never sent automatically and is deleted after 30 days; you decide whether to send it to us. The report does not contain your drawing.

Which AutoCAD versions does it work with?

It is built for AutoCAD 2013-2027 (64-bit). The version it is used and tested in every day is AutoCAD 2021; the others have not been tested yet. Try it on yours with the 7-day full trial before you buy; tell us how it runs and we will update the list.

Does it work in AutoCAD LT?

No. AreaPilot uses AutoCAD's .NET add-in platform, and AutoCAD LT does not load this kind of add-in.

How do I uninstall it?

Windows Settings → Apps → Installed apps → AreaPilot → Uninstall. The add-in files and settings are removed. The trial record stays on the computer (reinstalling does not restart the trial).

Feedback

If something went wrong or did not work as you expected, write to: destek@ostlertech.com

Your AutoCAD version and the AreaPilot version (in the top band of the window, next to "Area Takeoff · Quantities")
What you did, what you expected, what happened
A screenshot if possible. For the error report, type AREAPILOT_HATARAPORU at the command line; the report is copied to the clipboard, paste it into your email.

You do not need to send drawing files. If a problem can only be shown with a drawing, send a small part without client information; we use it only to find the problem and delete it within 30 days.

Privacy

AreaPilot and your data

Your drawings never leave your computer. AreaPilot measures areas inside AutoCAD on your computer. Excel exports are saved only to the folder you choose.
Update check: the first time the AreaPilot window opens in each AutoCAD session, the app reads a version file on ostlertech.com. No drawing, user name or license information is sent; the server hosting our site (Vercel, USA) keeps the requesting IP address in short-lived server logs. Without internet the check is skipped. If a new version exists you are asked; if you choose "Yes", the download page opens in your browser.
License operations: only if you entered a license key, AreaPilot connects to ostlertech.com when you activate it (the license key, a random device number and the application version are sent), when you press "Remove from this computer", when you choose "Reset my devices (email)" and, while AreaPilot is running and the computer is online, about every 7 days for a license status check (only the license key and the device number are sent). Your drawing, user name and computer name are not sent. If the status check cannot be made, your license keeps working. In the trial and free mode nothing is sent for the license.
Error reports stay on your computer: if an unexpected error occurs, details are written to %LOCALAPPDATA%\OstlerTech\AreaPilot\hatalar and reports older than 30 days are deleted. Nothing is sent automatically. The app offers to copy the report to the clipboard; if you want to send it to us, paste it into an email. Drawing content is not written and your user folder path is hidden, but an error message may contain a file or layer name, so please look before sending.
Settings and trial: language, theme and measurement settings are stored in the Windows registry (HKEY_CURRENT_USER\Software\OstlerTech\SpaceCalc) and removed when you uninstall. The trial start date is stored in the HKEY_CURRENT_USER\Software\OstlerTech\AreaPilot\Deneme key and in %LOCALAPPDATA%\OstlerTech\AreaPilot\deneme.txt; it is kept after uninstalling so the trial does not restart. You can delete that file and the HKEY_CURRENT_USER\Software\OstlerTech\AreaPilot key by hand.
No ads, analytics or usage tracking.
