There are a number of Engineering focused software tools that have started to support Extended Reality (XR). Some of these tools are fully immersive (VR) while others allow for blended (AR) experiences. All of the software will have some hardware requirement before the user can experience XR.
While many of these software titles can display their native file formats in XR, nearly all can import other popular 3D formats. Although Unreal Engine is a game development platform, it offers the DataSmith import tool capable of reading a variety of CAD file formats. There's no need to worry if your models were created in another tool but sometimes imported data might need some cleaning up.
