If I understand you, RMB on the drawing view, choose Properties, and choose the correct configuration there.
Your drawing view is most likely set to the current configuration. So as Glenn said, right click the drawing views, select properties, and under Configuration Information click the Use named configuration bubble. Then on the drop down menu select which configuration you are wanting to show in the view.
Good morning Mike,
Let me assume that you are showing the welded and machine version on the same page, right?? If you show the different configurations on a separate page they should work where you have one page Welded and the other Machined..
Normally the front view is the main view and all views follow from there.
Right Click like Glenn says and choose the correct configuration, in the property dialog box in the configuration drop down menu there is a place where you can link the different views and that could be your issues. By choosing the different configuration it should automatically break the link, unless there is another setting we are missing.
