2. FreeCAD - Wikipedia

   en.wikipedia.org/wiki/FreeCAD

   FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...

3. Engineering drawing - Wikipedia

   en.wikipedia.org/wiki/Engineering_drawing

   The metric drawing sizes correspond to international paper sizes. These developed further refinements in the second half of the twentieth century, when photocopying became cheap. Engineering drawings could be readily doubled (or halved) in size and put on the next larger (or, respectively, smaller) size of paper with no waste of space.

5. 3D modeling - Wikipedia

   en.wikipedia.org/wiki/3D_modeling

   3D models can be the basis for physical devices that are built with 3D printers or CNC machines. In video game development, 3D modeling is one stage in a longer development process. The source of the geometry for the shape of an object can be: A designer, industrial engineer or artist using a 3D-CAD system

   Paid subscription plans provide added functions for DesignSpark Mechanical, such as Mirror tool, full support of popular file formats such as STEP, STL, IGES, DXF, and DWG, and an associative drawing environment, adding many functions such as cosmetic threading, geometric dimensioning and tolerancing, annotations, and more.

7. Solid modeling - Wikipedia

   For a window, the sides might be defined as being parallel, and of the same length. Parametric modeling is obvious and intuitive. But for the first three decades of CAD this was not the case. Modification meant re-draw, or add a new cut or protrusion on top of old ones. Dimensions on engineering drawings were created, instead of shown ...

9. 3D projection - Wikipedia

   en.wikipedia.org/wiki/3D_projection

   A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.
