Parasolid XT
Parasolid is a 3D solid modeling kernel by Siemens. The XT format is its text-based exchange format, used by NX, Solid Edge, SolidWorks, and other Parasolid-based CAD systems. LinkCAD exports 2D layout data as extruded 3D Parasolid XT geometry.

How It Works
LinkCAD takes each 2D polygon in the layout and extrudes it along the Z-axis by the specified height, producing 3D Parasolid bodies that can be opened in Parasolid-based mechanical CAD tools.
Common Workflows
GDSII → Parasolid XT
Export IC mask layout to 3D Parasolid XT for use in NX, Solid Edge, or SolidWorks.
DXF → Parasolid XT
Convert 2D mechanical or packaging drawings into 3D Parasolid geometry.
Technical Notes
- Parasolid XT is export-only in public LinkCAD editions
- The 3D Modeler license bundle is required
- XT is the text-based variant; XB (binary) is not supported
