How can i get the 3d_model file of my model?

I want the 3d_model data and import it to unreal engine.But if i save my project, i only have a .rcproj file not a model file.anyone know what should i do for my project?

Hi giraffe_zhou,
you need to export your model from the project.
To do so, go to Scene 3D tab/Tools/Export/Mesh and PointCloud


There you set your wanted format and settings to export your model.
