It adds many 3D CAD file formats for storing and transmitting data. CAD file formats are classified in terms of two distinct forms. It offers bitmap or raster format and the vector format. The distinction clarifies the two formats by pointing out the critical difference between them.

The  raster  format adds images in terms of pixels. On a display monitor, the pixels work as dots that carry colour attributes and levels of intensity in RGB. Raster graphics are suitable for photographic images adding resolution-dependent. One does not need to scale higher resolutions without loss of quality. It uses an image that is grainier by adding image details. The  vector  format represents images as lines, points, curves and polygons on an algebraic grid. The primitives are utilised to create vector-based images. It scales up to any resolution without loss in quality.

The essential difference between raster and vector-based images covers raster images when scaled higher than the resolution we create. On the other hand, vector images are scaled up or down without any loss in image quality:

  • Popular raster-based formats include JPEG, PNG, BMP, and TIFF.
  • Popular vector-based formats add EPS,  PDF or AI, SVG (Scalable Vector Graphics), WMF (Windows Metafile Format), DXF (Drawing Exchange Format), DRW, and OB体育ob体育官网 formats.
  • Compound formats come with EPS, PDF, SWF, and PICT and contain pixel and vector-based data.

It determines whether the raster image format disappears from CAD file systems. This article answers all specific questions:

  • How popular is vector format based on leading CAD vendors?
  • Which CAD file formats come with 3D printing technology?
  • Is any particular CAD file format suited for CAD data exchange?
  • Why raster format remains an essential part of CAD file systems?

HOW POPULAR IS VECTOR FORMAT AMONG LEADING CAD VENDORS?

It offers modern CAD software packages storing  design  and drawing information in vector format. To confirm this observation, it’s worthwhile to look at CAD formats that lead to CAD vendors, such like:

  • AutoDesk is used as its native file format, supporting OB体育ob体育官网, DXF and more.
  • AutoCAD uses the OB体育ob体育官网 and DXF vector formats.

SolidWorks mainly uses a structured format in which different file formats are embedded. The design data are stored in the DXF vector-based formats covering AI, GCR, and STL. It keeps in a structured layout. The structured format also holds raster formatted images.

Many software applications can convert images between the raster and vector formats. It adds significant images that convert CorelDRAW, Easy Trace, WiseImage, Freehand, VP Software, and others. It leads to CAD vendors that convert between raster and vector file formats.  

WHICH CAD FILE FORMATS ARE MOST FAMOUS FOR 3D PRINTING TECHNOLOGY?

The format used for 3D printing comes with STL (STereoLithography) format. We aren’t sure whether any CAD file format is most suitable for 3D printing. It leads to 3D companies, including Stratasys and 3D Systems, that convert automatically into recognisable CAD files. Further, CAD vendors export their files into STL, including Catia, Autodesk Inventor, SolidWorks, SolidEdge and ProEngineer.

IS THERE ANY PARTICULAR CAD FILE FORMAT BEST SUITED FOR CAD DATA EXCHANGE?

There is no answer to this question. The  CAD  file exchange software will have the ability to convert between raster and vector formats. The reason requirement comes with a modern CAD file system. It moves towards a structured file format that works better in which both raster and vector file formats are embedded. The contemporary CAD files contain more drawings and design information. It makes sense to come with different file formats stored within a structure adding minimal information lost during file transmissions.

An excellent example is integrating different data types into a CAD file offered by BIM (Building Information  Modelling ). BIM helps incorporate activities for parties and disciplines involved in a building project. It comes with a synergistic body that exchanges different information types. With other teams working together on a project, it needs to use different file formats that add information exchange.

Also, the Raster formats need visual displays, virtualisation and animation. It’s vector formats that use design drawings which is scalable. BIM offers a valuable extension on the CAD file format that’s not recognised as a CAD file format. The complexities integrate CAD file formats adding necessary coin a different acronym for a unified file format that does not primarily contain CAD information.

The answer to the question “Is any CAD file format best suited for CAD data exchange?” is no, with qualifications. If the CAD data is exchanged strictly in design drawings, the vector format is best suited for the data exchange. It comes with scalability and without loss of data information. The CAD data is exchanged strictly in pictorial views or animation. Then the raster format, created with a high enough resolution, works best suited for the data exchange.  

WHY WOULD THE RASTER FORMAT REMAIN AN ESSENTIAL PART OF CAD FILE SYSTEMS?

Although raster images not scale up without losing data, they are indispensable for conveying pictorial information and producing animations. The current trend helps store CAD data that leans toward structured file format in which different file formats embed. As each primary CAD format has its right, the raster format undoubtedly remains an essential part of CAD file systems.
