Can I create UE5 Game that is in fact a CAD editor.

CAD editor

Yes you can! It would however be a lot of work, and the performance would probably be worse than the existing CAD editor as Unreal Engine isn’t built for this type of work.

Hey there @Chris-FMGL! Welcome to the community! The answer is a bit mixed. The short answer is yes, but with caveats. The long answer depends entirely on your skill set. Since the Datasmith SDKs aren’t totally meant to create CAD objects in engine, you’ll need to work on your own implementation. Performance is also going to take a massive hit unless you gut the engine down to it’s bare essentials, which also requires some solid C++ knowledge.

Oh Elias beat me again!
