You can lay out a curve like this in Autocad just fine though, in Turbocad,
you can edit the shape in ways Autocad can't.

Sure, most CAD packages can do curve fitting or there not very much
"CAD." I do it in turbocad. However, historically the problem with
Autocad is that its more of a workbench. Its a corporate product and
lots of the nifty features come in add-ons that you also have to pay
for. But this particular feature should be built in. It may not be
tweakable by the parameters you wish to tweak, but it can be done.
