How do you dimension an Oval?

[spark]

Louis i have turned on the center points for arcs but they only show up when i select the oval so how am i supposed to dimension to them?

There are two tragedies to this tale: arc centers don't display for ovals unless you select them and dimension's don't dimension the center points for ovals. Here's a solution I came up with (I did this in X1.5): copy your oval, paste hold position, convert to a polyline solid, place point markers (CAD >> Point Marker) where the arc centers show up, delete the polyline solid, and dimension the point markers.

Hope that helps.
