Important: The legacy fast zoom setting is ignored, but the prompt has been retained for script compatibility.

VIEWRES controls the appearance of circles, arcs, splines, and arced polylines using short vectors. The greater the number of vectors, the smoother the appearance of the curved object. For example, if you create a very small circle and then zoom in, it might appear to be a polygon. Using VIEWRES, you can increase the tessellation of the circle.

Note: After changing VIEWRES, the drawing is regenerated. Increasing the tessellation value of VIEWRES may result in an increase of the time it takes to regenerate the drawing. The value set is double the maximum number of vectors used to approximate the curve.

Even with WHIPARC enabled, not all objects can be natively drawn by hardware thus those objects will be tessellated and subject to this setting.

When a named (paper space) layout is made current for the first time and a default viewport is created in the layout, the viewing resolution for this initial viewport is the same as the viewing resolution for the Model layout viewport.

The VIEWRES setting is saved in the drawing. To change the default for new drawings, consider specifying the VIEWRES setting in the template files of which you base your new drawings.
