CAD software packages can be costly, which can cause issues when you want to view/open CAD files supplied by a designer. A free CAD viewer may be a good option if you wish to view a 3D model without making design edits.
In some cases, you’ll need to choose a CAD viewer that’s compatible with proprietary files. Unfortunately, you may need to download a different viewer software to open different types of CAD software files.
Autodesk Viewer
The Autodesk Viewer is a good option on the market for viewing various types of CAD files. The viewer is free and runs on your web browser (no installation required).

📡 Note: To make viewing files more accessible, you can ask clients to send a neutral and proprietary CAD file format. Neutral CAD file formats may exclude some data, but you’ll be able to open and view the CAD files with a basic viewer. Examples of neutral file formats include STEP, IGES, Parasolid, STL, VRML, X3D, COLLADA, and DXF.
