When you import a model, it is opened as a new model. If you import any other file, it is opened in the current model window.
Use one of the following methods to import data:
powershape -file f1 -import f2
where f1 is the name of the model and f2 is the path of the imported file.
You can also use the following commands:
powershape f1 f2
powershape -import f2 -file f1
To import a file into a new model, type one of the following commands:
powershape -import f2
powershape f2
To specify advanced data import settings, select File > Options > Data Exchange > Version 8/Surfaces and use the Import options.
You can also import materials to apply to shaded models.
