The "2D market" most likely refers to the 2D CAD (Computer-Aided Design) market. This sector remains structurally strong and distinct from 3D, valued at about USD 5.4 billion in 2025. It serves as the primary tool for creating documents like construction drawings and fabrication details. The market features a tiered structure with high-margin leaders like Autodesk and a long tail of smaller vendors.https://www.wiseguyreports.com/reports/2d-market
