People who regular to draw graphics will have such an experience, the painted circle is not round, into a polygon.

Computer screen do not know the round, CAD-round polygon, said polygon shown in the number of edges depends on the size of the circle in the current figure, as well as circle and arc smoothing degree: viewres, parameter settings. CAD will automatically calculate the circle displayed in the most appropriate number of edges. Viewres variable is set too low, or round a sudden is magnified many times, the circle will appear as obvious polygons. If the graphic is the Debu round amplified directly enter the RE command to re-draw a circle on the view will be rounded, if the size of the circle shows the right, still shows the polygon, the viewres parameters can be set a little larger, and then RE .

The Viewres variables can also be set in the Options dialog box: OP (option)----- Show ------ circles and arcs smoothness

You can also clean up the drawing process, this can increase the display and operating speed, but need to pay attention to the contents of the cleanup, such as some linear layers, text styles, dimension styles may be used later, do not clean up these Cleanup dialog box can be selected.

Solution 2: WBLOCK command.

Need to send graphics WBLOCK command to block the way to generate new graphics files to the new generation of graphics files to send or archive. The effect is the same as clean up, because the redundant data in the write block file will not be written to the block file.
