FAQ

Note: With the v2026.0 release, Topcon returned its office and field software to the MAGNET name. Topcon Office is now MAGNET Office, Topcon Field is now MAGNET Field and version numbers now follow the year (for example, MAGNET Office 2026.0).

Topcon provides four primary field software options designed around distinct job roles and construction phases:

• Topcon Field supports full survey and advanced layout workflows using GNSS and optical instruments.
• Topcon Field Mobile delivers core layout and verification tools in a simplified mobile friendly experience.
• Pocket 3D focuses on grade checking, earthwork verification and machine control support.
• Topcon Digital Layout is purpose built for vertical building layout by concrete, steel and MEP trades.

Side by side selection guide

This overview highlights how each field application aligns with different responsibilities on the jobsite. Many organizations deploy multiple tools across crews rather than relying on a single solution.

How to choose the right field software

• Select Topcon Field when survey grade accuracy and combined GNSS and optical workflows are required
• Select Topcon Field Mobile when crews need layout and verification without full survey functionality
• Select Pocket 3D when earthwork, grade checking and machine control drive the jobsite
• Select Topcon Digital Layout when vertical construction trades need accurate layout without survey training

• Topcon Tools is a lightweight, standalone desktop tool for file conversions, GNSS and total station processing, QA/QC, adjustments, localization, visualization and reporting. It is often used as a preprocessing step before Topcon Office or other CAD workflows.
• Topcon Office Base is the core desktop environment for import/export, data prep, basic QA/QC, reporting, and light drafting. It is the foundation product for adding Survey and or Site Prep modules.
• Topcon Office Base + Survey adds survey-grade computation, adjustments, GNSS processing, richer COGO, drafting, and professional survey delivery workflows. Topcon Survey includes all the functionality of Topcon Tools.
• Topcon Office Base + Site Prep adds modeling and construction takeoff capabilities for surfaces and corridors, volumes, and file prep tools for GPS-guided machine control systems.
• Topcon Office Base + Survey + Site Prep is the complete office suite that unifies survey computation and adjustment, drafting, surface and corridor modeling, quantities and volumes, and machine-control data prep. Topcon Survey includes all the functionality of Topcon Tools.

Side by side selection guide

This overview highlights how each office product aligns with different responsibilities. Many organizations start with Office Base then add Survey and or Site Prep as their needs expand. :contentReference[oaicite:0]{index=0}

How to choose the right office software

• Select Topcon Tools when you need a standalone “Swiss Army knife” for help converting to/from an expansive variety of filetypes, survey processing, QA/QC, least-squares adjustment, localization, and reporting without CAD production, modeling, or takeoff.
• Select Topcon Office Base when you need a core office hub for import/export, coordinate setup, cleanup, reports, and light drafting
• Select Office Base + Survey when your office delivers survey-grade computation including control, traverse, GNSS processing, adjustments, and robust COGO deliverables
• Select Office Base + Site Prep when your focus is surfaces, corridors, volumes, takeoffs, and machine control data prep
• Select Office Base + Survey + Site Prep when your team needs the complete suite for survey delivery plus modeling, takeoff, design, and machine control workflows

Note: With the v2026.0 release, Topcon returned its office and field software to the MAGNET name. Topcon Office is now MAGNET Office, Topcon Field is now MAGNET Field and version numbers now follow the year (for example, MAGNET Office 2026.0).

With the v2026.0 release, Topcon returned its office and field software to the MAGNET name. Topcon Office is now MAGNET Office, Topcon Field is now MAGNET Field and version numbers now follow the year (for example, MAGNET Office 2026.0). The products work together to move survey and construction data between the office, the field and machine control.

MAGNET Office (formerly Topcon Office) is CAD and design software for contractors and surveyors. It combines plans and survey data to build 3D digital terrain models for site survey, layout and machine control. Optional Site Prep and Survey modules add road and site design and finished survey CAD deliverables. Click here to learn more about MAGNET Office

MAGNET Field (formerly Topcon Field) is data collection software that turns a rugged tablet or compatible Android device into a field controller for Topcon GNSS receivers, robotic total stations, scanning robotic total stations and digital levels. It is used for land surveying, stakeout, construction layout, roadwork and utility mapping. Click here to learn more about MAGNET Field

MAGNET Enterprise (also called Topcon Enterprise) is a cloud service for sharing project data between office teams, field crews and machine operators. Files can be shared and converted for use in MAGNET Office, Sitelink3D and Autodesk or Bentley software. Click here for Topcon’s software eBook (PDF), which covers MAGNET Enterprise

CAD Platform

MAGNET Office is a standalone Windows program with its own drafting, design and surface modeling tools. It does not run on top of another CAD program. It imports and exports AutoCAD DWG and DXF files, and MAGNET Office 2026.0 added import of Revit (RVT) models.

If you also work in AutoCAD or Revit, Topcon Exchange for Autodesk adds a ribbon to those programs for creating Topcon machine control and survey files and sending them to the field through MAGNET Enterprise.

Note: With the v2026.0 release, Topcon returned its office and field software to the MAGNET name. Topcon Office is now MAGNET Office, Topcon Field is now MAGNET Field and version numbers now follow the year (for example, MAGNET Office 2026.0).

This is a running list of the minimum system requirements for the current release of Topcon MAGNET Office. We update it as Topcon releases new versions. Last updated October 2026.

Good news: MAGNET Office runs on modest hardware by today’s standards. The one item to check closely is the processor. Topcon calls for a 64-bit quad-core processor with AVX support. Most recent Intel Core and AMD Ryzen processors support AVX, but some older or budget processors do not.

Per Topcon’s system requirements, MAGNET Office needs an internet connection for online activation and for some features.

As of October 9, 2026, these are the requirements for MAGNET Office 2026.0 (formerly Topcon Office, release notes dated July 2026).

• Windows 11 64-bit or Windows 10 64-bit
• Internet connection for online activation and some features

Minimum hardware:

• 64-bit quad-core processor with AVX support
• 2 GB RAM or more recommended
• 2 GB or more of local hard drive space recommended
• 1280 x 1024 display resolution

Notes: Topcon lists one set of requirements for MAGNET Office, including the Site Prep and Survey modules. Topcon lists 2 GB of RAM, but large surfaces, point clouds and background images will likely run better with more memory.
