This software will allow you to view CAD models quickly and efficiently. You can open and view .stp or .step file formats.

Here’s what STP Viewer can do for you:

• Even if you’re not a CAD expert, you’ll be able to see 3D objects and rotate them
• Has a very detailed help for newcomers that will explain every tool available in the viewer and how to use it properly
• You can view the model as a tree structure, examining all the markers used to build it (you can easily get rid of it by using the hide command)
• Access to the object in 2D from all 4 sides (top, bottom, right, left)
• Choose to see the object as wireframe or add lightning to see how it will look in reality
• Change the colors as you see fit

Download STP Viewer if you want to see CAD models contained in .stp or .step files.
