Strata 3D works with original models that you create, and with files made in other applications.
Models are stored as files with all accompanying textures, effects and shapes. When a model is being worked on, it is loaded into RAM and is available for editing. You can create new models or load existing models, and then edit and save these models.
Choose Open from the File menu, or click on the Open icon on the Button bar. In the dialog, locate the folder and open it.
Use the Open As command in the File menu, and choose from the list of supported file types.
