Parasolid Designer is a comprehensive 3D modeler suitable for demanding applications in solid modeling, facet modeling, generalized cellular modeling, direct modeling, and free-form surface/sheet modeling. More than 900 functions are available to create, manipulate, interrogate and store 3D models. Parasolid is a 3D geometric modeling kernel technology, developed and owned by Siemens Product Lifecycle Management Software Inc. Parasolid was initially developed by Shape Data in Cambridge, UK. McDonnell Douglas Unigraphics acquired Shape Data in 1988 and deployed Parasolid as the kernel for their new ‘UG/Solids’ CAD system.
Parasolid v32.1 delivers initial support for lattice structures and continued expansion of Convergent Modeling™ functionality on mixed models. In addition, there are enhancements across a broad front of established functionality:

Native Lattice Support in Parasolid
Lattices are supported in Parasolid v32.1as a new geometry type to address the need to accurately represent latticematerials in parts intended for additive manufacturing. Initial functionalityincludes:
- support for general lattices consisting of cylindrical or conicalrods connected by spherical balls for regular and semi-regular structures
- operations include create, enquire, edit, delete and validatewith the Parasolid checker
- lattices may be converted easily to meshes for downstreamoperations
- lattices may be rendered as wire frame or as solid primitives(spheres, cylinders, cones)

Convergent Modeling
Convergent Modeling has been extended to operate on models containing a mix of facet B-rep surfaces and all classic B-rep surfaces. Specifically, at v32.1, support has been added for cones, tori, b-surfaces, blend surfaces, swept surfaces, spun surfaces and offset surfaces. Also, more operations now work on mixed models, including:
- transform faces that meet at a mixed edge
- apply non-rigid transforms to general facet or mixed bodies
- blend mixed edges along non-smooth chains and along open chains
- allow smooth overflow on blends along mixed edges
- patch faces with facet geometry and delete loops in faces withfacet geometry

Classic Modeling
Parasolid v32.1 includes a significant numberof enhancements to classic functionality, including:
- create step faces on boundary edges when radiating faces
- offsetting non-smooth (non G1) chains of edges imprinted oncomplex surfaces of all types and choose how to fill gaps between the resultantoffset edges
- create outline curves from general or wire bodies
- ability to supply reflection transforms to outline operations
- produce more rounded lofts when using face, vector or planarclamps and more rounded sweeps when using face clamps

Further information
Parasolid is a geometric modeling kernel originally developed by Shape Data Limited, now owned by Siemens PLM Software (formerly UGS Corp.), that can be licensed by other companies for use in their 3D computer graphics software products.

Parasolid's capabilities include model creation and editing utilities such as Boolean modeling operators, feature modeling support, advanced surfacing, thickening and hollowing, blending and filleting and sheet modeling. Parasolid also includes tools for direct model editing, including tapering, offsetting, geometry replacement and removal of feature details with automated regeneration of surrounding data. Parasolid also provides wide-ranging graphical and rendering support, including hidden-line, wireframe and drafting, tessellation and model data inquiries.
When exported from the parent software package, a Parasolid commonly has the file extension .x_t. Another format is .x_b, which is in binary format so it is more machine independent and not subject to binary-to-text conversion errors. Most Parasolid files can communicate and migrate only 3D solids and/or surface data - Parasolid files currently cannot communicate and migrate 2D data such as lines and arcs.
To use Parasolid effectively, users need to have fundamental knowledge of CAD, computational geometry and topology.
Applications[edit]
It is used in many Computer-aided design (CAD), Computer-aided manufacturing (CAM), Computer-aided engineering (CAE), Product visualization, and CAD data exchange packages. Notable users include:
