I have been asking for this *^$%# feature forever.
I've been using Adobe Illustrator for over a year and I still cannot draw the same things which I can draw easily when I use Microsoft Expression Design and the B-Spline.
However I use a Mac, and I don't want to boot parallels every time I need to draw something.
For example... Try to draw a pear using the Adobe method versus the Microsoft method. It's *&$#%* impossible.
You would think a thousands of dollars program would include every *&%^*#$ possible spline tool known to man. Yet they include the most obtuse and impossible way of drawing curves. It's like the central core of what a vector graphics program aught to do, however they don't even support the form of curve supported in FREE software.
Then when you ask for it, they say that their tool is more powerful. Give me a *&#%& break. I have been trying to use it for over a year. You don't know what powerful is if you can't do *&#%& with it.
Bezier Curves were introduced into Windows NT and all windows NT family products after that.
Adobe Illustrator was specifically designed to produce PostScript(TM) output from its very first version; and PostScript exclusively uses Bezier curves.
In addition, Adobe Illustrator v1.0 preceded Windows NT by about 7 years.
