Once you have organized the Article View, arranging the parts as needed, you can use the View Parts in Spec button rather than exporting the Article View to Spec.

The View Parts in Spec button is located between the Menu bar Toggle Tools and Calculations, in the top right of your CET window. 

The file that is exported to Spec is a .pmx file, proprietary to Spec. The exported PMX is generated from the active Article View in Calculations. If there is more than one Article View for the project, select the Article View prior to clicking the View Parts in Spec button.

Once exported, the PMX will open in Spec with the User's last saved or Favorite view. The parts will be listed in the same order as they appear in the Article View, with selected options, tagging categories listed, and any applied discounts.

Once in Spec, save the file using Save As to adopt the file name.
