Windows installers for both Isometra products. Each starts in a free edition with no account, and unlocks fully with a licence file — ask for a 14-day trial to try either one with no limit.

Isometra Workbench

Review IFC models, build spools and turn them into isometric drawings, PCF files and weight reports.

Installing

1. Run the installer. By default it installs for all users in Program Files and asks for administrator rights; choose Install for me only if you do not have them.
2. Windows may say “Windows protected your PC” and show an unknown publisher, because the installer is not code-signed yet. Check that the SHA-256 above matches your file, then choose More info and Run anyway. To check it, open PowerShell in the folder of the file and run Get-FileHash .\IsometraWorkbench-Setup-0.1.6.exe -Algorithm SHA256.
3. Open the program and choose File > Open example to see it on a small project with comments, saved views and ship references.

Licence

The program starts in the free edition: 3D review, measurements, sections, comments, and opening and saving projects, with no licence and no account. The paid features (piping, spools, isometrics, PCF, weights, BCF, version compare and collision detection) unlock with a licence file. Your projects and files always open and save, whichever edition you are on.

To try the paid features, ask for a 14-day trial licence: it is a licence file with every Pro feature that stops after 14 days, counted from the day we issue it. To buy, see Pricing. A licence file is tied to one computer: Help > Licence shows its Machine ID, which you send with your request.

What you need

• Windows 10 (version 1809 or later) or Windows 11, 64-bit.
• The Microsoft Edge WebView2 Runtime, which Windows 11 and most Windows 10 already have; the installer adds it if it is missing (it then needs an internet connection once).
• No internet connection is needed to use the program, and your models never leave your computer.

Uninstalling

Windows Settings > Apps > Installed apps > Isometra Workbench. The uninstaller asks whether to keep your settings and licence.

Isometra ACAD2IFC

An AutoCAD add-in that exports solids, wireframe geometry, blocks and text of any drawing to IFC2X3.

Installing

1. Close AutoCAD if it is open, then run the installer. It installs for your Windows user only, in %APPDATA%\Autodesk\ApplicationPlugins — the folder AutoCAD 2026 itself scans for add-ins to load automatically, so no administrator rights are needed.
2. Windows may say “Windows protected your PC” and show an unknown publisher, because the installer is not code-signed yet. Check that the SHA-256 above matches your file, then choose More info and Run anyway.
3. Open (or restart) AutoCAD 2026. Isometra ACAD2IFC loads by itself and shows a splash screen; run ACAD2IFCPANEL to open its window, or use its commands directly from the command line.

Licence

The add-in starts in the free edition: it exports straight away, with no account, capped at 25 entities per export and 3 files per batch. A licence file, tied to your computer, removes the cap, at €250 per user per year — see Pricing. Your drawings and exports always work, whichever edition you are on.

To try it with no cap, ask for a 14-day trial licence: a licence file with no cap that stops after 14 days, counted from the day we issue it. A licence file is tied to one computer: the Licence menu shows its Machine ID, which you send with your request.

What you need

• Windows 10 or 11, 64-bit, with AutoCAD 2026 installed.
• No internet connection is needed to use the add-in, and your drawings never leave your computer.

Uninstalling

Windows Settings > Apps > Installed apps > Isometra ACAD2IFC. The uninstaller asks whether to keep your licence file.

Isometra RHINO2IFC

A Rhino plug-in that exports solids, surfaces, NURBS curves, blocks and text of any model to IFC2X3.

Installing

1. Close Rhino if it is open, then run the installer (it asks for administrator rights: Rhino's own plug-in registration is a machine-wide registry key, not a per-user one).
2. Windows may say “Windows protected your PC” and show an unknown publisher, because the installer is not code-signed yet. Check that the SHA-256 above matches your file, then choose More info and Run anyway.
3. Open (or restart) Rhino. Isometra RHINO2IFC loads by itself and shows a splash screen; run RHINO2IFCPANEL to open its window, or use its commands directly from the command line. If it does not appear, drag RHINO2IFC.rhp (in the install folder) onto a running Rhino window once — Rhino registers it itself the same way.

Licence

The plug-in starts in the free edition: it exports straight away, with no account, capped at 25 entities per export and 3 files per batch. A licence file, tied to your computer, removes the cap, at €250 per user per year — see Pricing. Your models and exports always work, whichever edition you are on.

To try it with no cap, ask for a 14-day trial licence: a licence file with no cap that stops after 14 days, counted from the day we issue it. A licence file is tied to one computer: the Licence menu shows its Machine ID, which you send with your request.

What you need

• Windows 10 or 11, 64-bit, with Rhino 7 or Rhino 8 installed.
• No internet connection is needed to use the plug-in, and your models never leave your computer.

Uninstalling

Windows Settings > Apps > Installed apps > Isometra RHINO2IFC. The uninstaller asks whether to keep your licence file.
