I have to admit I had similar confusions when I started using Poser 5. You have two options:-

ONE

• Pose Judy in frame one and in the cloth room set the drape frames to at least 30. Maybe higher if that doesn't produce good results.
• Select the "drape from zero pose" option.
• Calculate the simulation

TWO

• Load Judy and set at the zero pose in frame 1.
• Advance to frame 30 and set the pose.
• Now in the cloth room set your simulation to 30 frames.
• Leave drape frames at zero.
• Calculate the simulation.

Now a couple of notes. I tend to use method two because I have more control over the simulation. Sometimes the best look to the cloth appears at say frame 28 rather than 30. If I had opted to calculate all my cloth movement using "drape" I'd only have the start and end frames to work with. There are times when you'd want to add some frames at the end i.e. 30 frames of Judy getting into position, followed by 30 frames to allow the cloth to settle. Lastly I its not essential to start with Judy in the zero pose because the "drape from zero pose" takes care of it. However it gives me an initial indication that the dress fits correctly before I spend the time on the simulation.
