Defining the View Origin
By default, the origin of a drawing view is in the center of its outline. You can reset the origin of a drawing view by parametrically referencing model geometry or defining a location on the drawing sheet. Designating an origin identifies the view location on the drawing and prevents it from shifting whenever the model geometry changes.
You can reset the origin of general, auxiliary, and broken views any time after you create them, but it does not change the current position of the view. The effect of the new origin is noticeable only when the system updates the views to reflect changes in model geometry. However, if you reset the origin of a perspective view, it alters the current position of the view because the view origin is part of the orientation.

You cannot change the view origins of total unfolded cross-sectional views.

To select the point for the origin, you can choose a model edge, datum curve, datum point, coordinate system, or cosmetic feature entity. However, when selecting a point, keep the following in mind:
• For a general view, the selected point becomes fixed.
• For a projection and auxiliary view, the system passes the selected point onto a ray passing through the origin of the parent view in the direction of projection. This projected point becomes the origin of the view.
• To select a coordinate system as the origin of a newly created view, specify its name as the value for drawing_view_origin_csys configuration option . If you do not want the system to use a coordinate system that you set previously, specify the value as no.
