DWG is merely descriptive of applicant's goods under Section 2(e)(1) of the Trademark Act for two reasons: (1) DWG is a recognized abbreviation for "drawing," and (2) .dwg is a file format used for computer-aided design (CAD) drawings made both with applicant's CAD software and others' CAD software.
Checkers, software that analyze CAD data formats, are often employed before and after data translation. The checkers can check the organization and quality of the data against internal company standards and international or industry standards.
AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a computer-aided design (CAD) data file format developed by Autodesk [2] to enable CAD data exchange and interoperability between AutoCAD on different computing platforms.
The notes list provides notes to the user of the drawing, conveying any information that the callouts within the field of the drawing did not. It may include general notes, flagnotes, or a mixture of both. Traditional locations for the notes list are anywhere along the edges of the field of the drawing.
Rainscreen cladding is a form of weather cladding designed to protect against the elements, but also offers thermal insulation. The cladding does not need, itself, to be waterproof, merely a control element: it may serve only to direct water or wind safely away in order to control run-off and prevent its infiltration into the building structure.
PMI can be used to generate annotation on a traditional 2D drawing the data. However, generally, PMI is used to visualized product definition within the 3D model, thus removing the need for drawings. Some 3D model formats enable computer-aided manufacturing software to access PMI directly for CNC programming.
DGN (design) is the name used for CAD file formats supported by Bentley Systems, MicroStation and Intergraph's Interactive Graphics Design System (IGDS) CAD programs. [1] The DGN format is used in construction projects, including buildings, highways, bridges, process plants, shipbuilding. DGN is a competing format to Autodesk's DWG. [1]
Dick Newell oversaw the creation of the Plant Design Management System (PDMS) for 3D process plant design. He later co-founded two software companies – Cambridge Interactive Systems (CIS) which was known for its Medusa 2D/3D CAD system, and Smallworld with its eponymous Smallworld GIS (Geographical Information System).
