The standard for exchanging product data or STEP files is an ISO standard exchange format to work with three-dimensional data. It is used to design 3D diagrams. We use a step file viewer free to view, rotate, move, and zoom the 3D diagram. Because it can deal with *.stp and *.step file formats; moreover, it can convert STP to DWG, OBJ, DXF, and STL formats.
What is a STEP File?
STEP file is a computer-aided design (CAD) data exchange form and related information. It follows the ASCII structure, so it is straightforward to read. 3D graphics use STP file extension, defined in ISO 10303-21.
A STEP file is a p21 and a STEP physical file. 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, sharing 3D diagrams and models among different users is challenging. STEP File Reader software solves this problem. It can open the files which have .stp and .step extensions. It is used for some reasons, which are as follows:
- STEP is used for the worldwide data exchange program
- All the popular computer-aided design (CAD) software supports this platform.
- It is mathematically based so that it can be imported into CAM software.
- Any reputed CAD software can read a neutral file format.
Difference Between.Step and . Stp file Viewer
The.STEP and . STP files are the same, and there is no significant difference. However, the user downloads/exports the file in different modes. But you can open both .step and .stp files with any STP file viewer.
Which Program Can Open Step File Online?
STP viewer windows is interrelated with CATIA. Any commercial CAD Software can open it. There are a lot of ways to open step files online. Besides online step viewer, some other *.stp file viewer are:
- Autodesk Fusion 360.
- IMSI TurboCAD Deluxe v7.

How to Convert STP to PDF/DWG
All the software does not support converting STEP to PDF. However, you can follow the 30 Best PDF Converter. Here, you will get the guidelines.
STP File Viewer Online VS Windows STEP Viewer
From my experience, I have seen the problem of selecting the best stp viewer. STP file viewer online and offline free .stp viewer has a big difference.
.STP File Viewer
Offline Step File Viewer
|Online step viewers are easy to access from anywhere.||You have to get access only from a particular device.|
|There are a lot of free online STP online file viewers.||Offline step viewer is not free, but you can use the free trial for a limited time.|
|You will get a lot of options, but quality is a significant consideration.||Quality is the first choice of offline mode.|
|The general users usually use the Stp file viewer online.||The professionals and engineers use the offline Step file viewer.|
Standard Features of STP Viewer
Each .stp file viewer is different from another .stp viewer. However, some of the standard features of the .stp file online file viewer and free stp viewer are:
- Users can see 2D views of 3D objects on all four sides.
- Excellent tree view of all 3D object markers.
- Fabulous dynamic zooming.
- Dynamic rotation with the toolbox.
- Users can change the color and shade of a 3D object.
OS: Windows Server 2003 & 2008; Windows XP, Vista, 7,8 and 10
Microsoft .NET Framework 2.0 (included in Windows XP SP2, Vista, Windows 7).
Online: Any Platform that has a good web browser.
Why do you need a STEP Viewer?
STP viewer windows are required for engineering students and professionals. When you open a 3D object, you need a step file reader to see every detail of the object. You can see the 3D object separately by tree view.
STEP file view lets you see the 3D object like the real one. The online STP viewer helps to collect various templates and images to make them more realistic.
Limitations of STEP
- STEP file is a combination of color, curve, solid, surface, etc., so it may create problems if the targeted software cannot read STEP’s geometry, 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.
