Update Drawing Views when Source 3D Models Change
Workflow to make out-of-date drawings current.
While you work on a drawing containing drawing views, the program
periodically checks whether the referenced 3D source model has changed. If
the source has changed, a balloon message displays next to the drawing views
status bar icon in the lower right of the application window. Click the link in
the balloon message to update all out-of-date views.
If you close the balloon without updating the views, a warning badge is
attached to the drawing view status bar icon. Furthermore, AutoCAD highlights
out-of-date drawing views by placing red markers on the corners of the view
border. You update an out-of-date view by right-clicking it and selecting
Update from the menu. Alternatively, you can use the Update View command
(or use the Update All Views command to update all out-of-date views) from
the drawing views ribbon panel.
Unlike Xrefs, drawing views do not update automatically when you open a
drawing. You must explicitly invoke the AMVIEWUPDATE command to update
drawing views.
Depending on the change in the source model, the view may grow or shrink.
There are two ways by which you can anchor a view in the drawing.
You can choose to center justify the view, so that the view grows or shrinks
about its center.
