I would like to rotate a specific drawing view 180° around the part's axis. Meaning I would like to look at the part from the opposite side while keeping the dimensions that are already added if possible. I do not want to create a new model view, or project view and add the dimensions again. I would like to modify the existing one. Attached is a picture of what I DO NOT want, if there is any confusion. Appreciate your help.
If I understand this correctly, you're looking for a method to rotate the view about the X axis. Am I correct?
If so, try this: Select the view, then select the standard view that is opposite from what you are currently using (if it is a front view, select the back view). This will show the opposite side of the part, but will put the thread on the right side of the view. Use the rotate view button to reorient the view 180 degrees so the thread is shown on the left side of the view.
Does this give you what you're after?
