Tinkercad is a free-of-charge, online 3D modeling program that runs in a web browser. [1] Since it became available in 2011 it has become a popular platform for creating models for 3D printing as well as an entry-level introduction to constructive solid geometry in schools.
Basic three-dimensional geometric forms (e.g., prisms, cylinders, spheres, or rectangles) have solid volumes added or subtracted from them as if assembling or cutting real-world objects. Two-dimensional projected views can easily be generated from the models.
FreeCAD's own main file format is FreeCAD Standard file format (.FCStd). [9] It is a standard zip file that holds files in a certain structure. [9] The Document.xml file has all geometric and parametric objects definitions. [9]
On May 18, 2013, Tinkercad announced it had been bought by Autodesk. [63] Tinkercad is a browser-based 3D solid modeling tool for rapid prototyping known for its simple interface and entry-level ease of use. [64] In October 2013, Autodesk signed an agreement to acquire structural fabrication and detailing software- Advance Steel from Graitec. [65]
CATIA (/ k ə ˈ t iː ə /, an acronym of computer-aided three-dimensional interactive application) is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), 3D modeling and product lifecycle management (PLM), developed by the French company Dassault Systèmes.
CADKEY is a 2D/3D mechanical CAD (computer aided design or computer aided drafting) software application released for various DOS, Solaris, and Microsoft Windows operating systems.
IntelliCAD is a CAD editor and development platform with an API published by the IntelliCAD Technology Consortium (ITC) through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of file types (i.e., .dwg, BIM, TIFF, etc.).
HeeksCAD supports cuboids, spheres, cylinders and cones as basic 3D solids. Further geometric objects may be created by sweeping or connecting 2D shapes. [3] [4] HeeksCAD makes extensive use of local coordinate systems. For example, these are used to define the drawing plane and the direction of an extrusion. [5]
