This was made with the "Polyline" function under "Polygon Primatives". Lets see what happens if you smooth this, using the "Smooth Polygons" function under "Polygon Constructions". This function may do several of the traditional polygon smoothing methods, the default being a uniform quadratic spline. To use the function just pick the polygon to smooth and hit OK. The smoothing type is a field of the resulting object. To try different smoothing types just right click on the smoothed polygon and choose "type". This gives a dialog for the setting of the "type" field.
Our first try is pretty bad. Lets try to improve it by adjusting the corners of the original polygon and adding some more corers too. Make the original polygon visible by finding it in the database and turning on its visibility. The easiest way to find it is to right click on the smoothed polygon and chose "Show In Tree". Then find the polygon field of the tree node that appears and expand it. The original polygon should be there. Expand that, and you will find the visibility field. Double click on it and a dialog appears that you may use to turn on the visibility. Now to adjust the positions of the corners, right click on the strait polygon and chose "Show Handles". In fact, it is possible to just right click on the smoothed polygon with the same result, and there was no need to show the strait one at all. This was just to show it still existed. There should now be some green squares on the screen that you may use to drag around the corners.
One property of the type of smooth we are using "Uniform quadratic spline" is if the
control polygon has the same vertex repeated (has a segment of zero length) the smoothed
curve will to right through that point. To get nice sharp serifs on the S what you need
to do is put doubled vertices at the corner. To add vertices to the control polygon
(the strait one) use the "Edit Polyline" function, which enables you to add and
remove vertices from a polyline. To add a vertex click the mouse over the segment you
would like to insert the vertex in and then pick the point to insert. You may use the
doubling buttons to a duplicate vertex. Once the vertices you need exist they can
be be moved around by using the handles. Handles are drawn specially for doubled
and tripled vertices. The handles may be used as object snaps: hit the "Point Snap"
tool.
