Best 15 STEP File Viewer Online/Desktop Free and Easy to Use

The standard for the exchange of product data or STEP file is an ISO standard exchange format to work with three-dimensional data. It is used to design 3D diagrams. To view, rotate, move, and zoom the 3D diagram, we use a step file viewer. Because it can deal with *.stp and *.step file format; moreover, it can convert STP to DWG, OBJ, DXF, and STL formats.

What is a STEP File?


STEP file is a data exchange form of computer-aided design (CAD) and related information. It follows the ASCII structure, so it is straightforward to read. 3D graphics use STP file extension, and it is defined in ISO 10303-21.

A STEP file is also known as p21 file and STEP physical file. It has various extensions like .stp, .step and .p21 whereas .p21 is used for different purposes. It can be recognized by many programs like IMSI TurboCAD, Autodesk Fusion 360, and Dassault System Solidworks.

Why use STEP Viewers?


All the CAD systems are not similar. So, in the CAD industry, it is challenging to share 3D diagrams and models among different users. STEP File Viewer software solves this problem. It can open the files which have .stp and .step extensions. It is used for some reasons which are as follow:

  • STEP is used for the worldwide data exchange program
  • All the popular computer-aided design (CAD) software support this platform.
  • It is mathematically based so it can be imported into CAM software.
  • Any reputed CAD software can read a neutral file format.

Limitations of STEP

  • STEP file is a combination of color, curve, solid, surface, etc. so if the targeted software is unable to read the geometry of STEP, then it may create problems.
  • The designer has to be more conscious to ensure the geometry is correctly generated to support another type of file format.
