Once the Upload All button is clicked, the selected file is put into a multipart form data object, following a specific method. The application validates the file as a supported CAD file and prepares the file to be imported in the Area by creating the set of temporary objects (Layer, Line and Block objects) needed for the following steps.
If these operations finish without an error the Next button is enabled, allowing the user to move to the second wizard step.
