SOLIDWORKS is a modeling CAD and CAE program by Dassault Systemes which runs on Windows. It is built on Parasolid kernel. SOLIDWORKS user base covers a very wide range of manufacturing market segments, such as aerospace, transportation, electronics, machinery, medical, etc.
SOLIDWORKS users are capable of drawing 2D and 3D sketches, creating models and assemblies, adding notes, dimensions and tolerances.
SpaceClaim is a solid modeling CAD application that runs on Microsoft Windows. It is developed by SpaceClaim Corporation, but now owned by ANSYS.
SpaceClaim’s 3D direct modeling technology is expressed by the following tools: pull, move, fill, and combine.
Pull contains most creation features which can be found in traditional CAD systems. For instance, using the Pull tool on a face by default offsets the face, but using the Pull tool on an edge rounds it.
Move relocates components and geometry, and can also be used to create patterns (often called arrays).
Fill primarily removes geometry from a part by extending geometry to fill in the surrounding area. It is commonly used for deleting rounds and holes from a model.
Combine merges parts and subtracts parts from each other.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
