2. You are prompted to select the entity for which you want information. Select the model on the workbench, and in the Access window select the orphan node of the part.
   Note

   Before importing the new Alias model, the Orphan Node of the original model is selected (active) for the replace routine to be used.

   Next, you will import the Alias wire file model which represents the changes that are required to be incorporated.

1. Choose File > Import. From the File Import list, choose Freeform Surfacing.
   
2. A popup window displays.

3. Choose OK.

   The I-DEAS List window displays the import progress and the new model is imported on top of the original geometry.

4. Once the model has been imported, if necessary, position the stitched geometry where you want it in relation to the existing part in I-DEAS Master Series.
5. Ensure that the orphan node of the original model is still active, and then choose Modify Entity.
   
   Note

   You must be able to stitch together this surface geometry once it is in I-DEAS Master Series to ensure its status as either a closed or open solid.

   Note

   For information on creating and confirming stitched geometry, see the Creating a Solid section.

6. A popup menu is displayed. Choose Replace Feature.

   You are prompted to select the geometry that will be used to replace the original feature.

7. Once you select the feature, you are prompted whether or not you want to control the associativity of mapping the old and new geometry.

   If you choose Yes, the screen splits into two areas. You are prompted to map the original geometry to the geometry of the newly imported model.

8. When the mapping has been completed, click the Update icon from the second section of the icon panel.
   

   The original feature is replaced by the imported geometry and a new feature exists with all the nodes acting upon the new Orphan Node.
