In the Assembly Save a Copy dialog, click [Save Copy and Open] to save the assembly under its new name, and open the newly saved assembly.

Close the 3DCS Model Navigator and Creo window for Lesson_3 Manual Gear shifter Asm.

Click DVTI_dcsUpdateModel Update Model in the new window for Lesson_4 Manual Gear shifter Asm.

Go to [File] arrowDCS [Save As].

In the Save As dialog, enter "Lesson_4 Manual Gear shifter Asm." as the new File name and make sure the type is set to Part Files (*.prt).

Click [OK] in the Save As dialog.

Click DVTI_dcsUpdateModel Update Model.

Go to [File] → [Save As].

In the Save as dialog, enter "Lesson_4 Manual Gear shifter Asm." for the File Name, and make sure the Type is set to Assembly (*.asm).

In the Assembly Save as dialog, click [Save Copy and Open] in the bottom left of the dialog to save the assembly under its new name, and open the newly saved assembly.

Click Update Model in the new window for Lesson_4 Manual Gear shifter Asm.

Click the MC Application Button Icon Application Button then select MC 7500 Save As Icon Save As.

Change the File Name to "Lesson_4 Manual Gear Shifter Asm"and make sure the Type is set to WTX DATA(*.wtx)

Name this measure “Shifter_Knob_Y_dir ". Give it the Description "top surface of Gear Shifter knob deviation in Y direction” (Description is not mandatory).

Select [Nominal-Point] for Measure Type.

Click the [Add All] button and select highlighted Surface on the Stick as shown below in the next image
