PLASTICITY File Format Explained

The PLASTICITY file format is the proprietary native format for Plasticity, a direct modeling CAD software tailored for artists and designers. It is designed to save precise geometric data for hard-surface modeling workflows.

PLASTICITY File Format Details What It Stores It stores Parasolid-based solid and surface geometry, curves, object organization, and related model data used by Plasticity. It supports direct editing of curves, surfaces, faces, edges, and solid bodies, but does not store parametric construction history, rigging, animation, or texture-based rendering data. Primary Use Cases Saving in-progress hard-surface concept designs. Archiving editable 3D CAD assets. Inter-software workflow preparation prior to mesh conversion. Strengths Retains precise CAD curves, surfaces, and solid body geometry. Smaller file sizes compared to dense polygonal meshes. Supports direct editing of curves, surfaces, faces, edges, and solid bodies. Limitations Not supported natively by standard DCC apps or game engines without export conversion. Lacks animation, rigging, and texturing capabilities. Common Software Support Primarily supported by Plasticity. Plasticity exports to formats such as OBJ, STL, STEP, Parasolid X_T/X_B, 3MF, SVG, and, in Studio workflows, SAT and IGES for external pipeline compatibility.
