Bringing tcpMDT® to progeCAD: An Aplitop Case Study
Three Months, One Familiar API, and a New Market: Aplitop's Journey Bringing tcpMDT to progeCAD
How a 20-year-old geospatial software company added another CAD platform to its lineup using the IcARX API, what the migration actually looked like, and what they wish had been easier.
This is part of a series sharing how development companies are using IcARX to bring their products to IntelliCAD-based CAD platforms. IcARX is the IntelliCAD Technology Consortium's ObjectARX®-compatible C++ API. For developers with existing ObjectARX projects, it offers a familiar API surface and a practical path to a new host CAD without a rewrite.
The Story
For more than two decades, Aplitop has built software for surveyors, civil engineers, and construction professionals. Their flagship CAD-based product, tcpMDT®, is in daily use in over 80 countries and runs on a handful of major CAD platforms. In late 2024 and through 2025, Aplitop added one more: progeCAD, the IntelliCAD-based CAD platform from progeSOFT.
