Transfer subdivision geometry between Alias and Autodesk SpeedForm

Transfer SpeedForm T-Splines from SF3D files to Alias

You can import T-Spine surfaces from SF3D files directly into Alias. When you import T-Splines, the models get converted to Alias subdivision objects. Creases in the T-Spline model are preserved in the resulting subdivision object. Symmetry that has been added to the T-Spline surface in SpeedForm is removed and is not transferred to the Alias subdivision object.

Note:

NURBS surfaces created in SpeedForm using the Detailing workspace are not supported.

  1. In Alias, choose File > Import > Subdiv, and browse to your SF3D file.

    Ensure that All Files (.) is selected in the file Open window so that your SpeedForm SF3D files appear.

  2. Click Open.

    Your T-Spline model is converted to an Alias Subdivision object.

Transfer subdivision objects as OBJ files

When you save an Alias subdivision object or a SpeedForm T-Spline object to an OBJ file, you can easy exchange these objects between the applications.

  4. In SpeedForm, choose File > Import, and browse to your OBJ file.

  5. Click Open.

  6. Use the Convert tool to turn the model into a T-Spline object by choosing Utilities > Convert.

You can now continue editing your Alias subdivision object in SpeedForm.
