9 Best Free STEP File Viewer Software For Windows

Here is a list of best free STEP file viewer software for Windows and STP viewer software for Windows. STEP files and STP files are more or less the same formats. STEP files and STP files are widely used to design 3D diagrams, so they require special software in order to be viewed.

Using these freeware, you can choose to rotate, move, pan, zoom, etc. your STEP files. Different views can be accessed from the options: top view, bottom view, front view, back view, left view, right view, etc. With some of these STEP file viewers, you can also apply various color schemes to STEP files. This lets you view the components of drawings in different colors and shades.

All of the mentioned STEP file viewers mentioned here are free to use. Go through the article to read more about them. You will also get to know how to view STEP files with these software on your PC.
