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 ...
In 2009 a license update of LibDWG/LibreDWG to the version 3 of the GNU GPL, [6] made it impossible for the free software projects LibreCAD and FreeCAD to use LibreDWG legally. [ 5 ] Many projects voiced their unhappiness about the GPLv3 license selection for LibreDWG, such as FreeCAD , LibreCAD , Assimp , and Blender . [ 7 ]
LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix/Linux, macOS, and Windows operating systems.. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application.
Image registration algorithms can also be classified according to the transformation models they use to relate the target image space to the reference image space. The first broad category of transformation models includes linear transformations , which include rotation, scaling, translation, and other affine transforms. [ 5 ]
The basis for STEP was the Product Data Exchange Specification (PDES), which was initiated during the mid-1980's and was submitted to ISO in 1988. [4] [5] The Product Data Exchange Specification (PDES) was a data definition effort intended to improve interoperability between manufacturing companies, and thereby improve productivity.

Georeferencing or georegistration is a type of coordinate transformation that binds a digital raster image or vector database that represents a geographic space (usually a scanned map or aerial photograph) to a spatial reference system, thus locating the digital data in the real world.
IFC-SPF is a text format defined by ISO 10303-21 ("STEP-File"), where each line typically consists of a single object record, and having file extension ".ifc". This is the most widely used IFC format, having the advantage of compact size yet readable text. IFC-XML is an XML format defined by ISO 10303-28 ("STEP-XML"), having file extension ...
