Create two curvilinear arcs, one on each side: that gives you a genuine circle, at least within the projection that you are using. There are examples in the Tracker: Measurements topic. There are many workflows possible, depending on your skill set, muscle memory, preferences, etc, but one simple way is to create a buffer "circle" of the desired radius (copy the center point first, so you can paste it, thus getting both the buffer and retaining the original center point), and then Transform - Convert to Point to make points. The purpose of that is have points that are easy to snap to for exact measurements. Next, with snapping on create a curvilinear line from one side of the buffer to the other, dragging the center handle of the circle arc to where it snaps to the edge of the circle. Create another curvilinear arc going in the other direction to the other side, and now you have a buffer. Curves are rendered onscreen using straight segments, but when you print them to pdf there are more segments used for a smoother look. See the attached pdf for an example. By the way, it's interesting to see the different sizes created by different print to PDF packages. Adobe print to PDF created a 223 KB file while Microsoft print to PDF created a PDF over 20 MB. (!) Also, the "smooth" transform is really more of a "simplify" transform. See the Transform Templates - Drawings topic. Attachments: circle_adobe.pdf
