How do you mean?
SW will give you a basic pattern.
You have your types : Drop Shoulder, Modified Drop (T), Set-In, Raglan, Vest, Shell, Tuxedo Vest.
Then you choose your style: Pullover or Cardigan
Neckline: Crew, Round (scoop), V, Placket, Boat, Square, Funnel.
And then your shape- Standard or A-Line
Some options disappear as you choose things, like you can't have a tuxedo vest pullover, it has to be a cardigan....etc...
Then you choose US or Metric, if it is for a Child, Woman, Man, Bear, Large Doll or Fashion Doll.
Choose the Chest size, Fabric weight (Light, Medium or Heavy) , Fit (Very Close, Close, Standard or Oversized) and Length (Crop, Top Hip or Tunic)
Next you drop in your gauge and then you are brought to the schematic where you can fiddle with the little things. You can change pretty much any of the measurements, and there are drop down menus to allow for things like collars, or additional neck lines like Turtle necks and cowls. Button Bands and such are there too, and I have never used it myself, but you can even put in your stitch repeats somewhere too...
It is handy. But again, my main problem with it, is because your sweaters are bigger projects, I find my swatch is never good enough and after knitting the first 4 inches or so of the sweater, I find out my true gauge and have to re plug in my gauge.
