Hi @esthervt, Welcome to the forum!
What is the message at the bottom left of your Seamly2D window, in the status bar?
If you’ve selected all the points and curves for your pattern piece, you can press ENTER.
You will see a popup like this: Click OK. And don’t forget to save your work! 
To view and refine your pattern piece, go to Detail mode by selecting the Detail icon in the top menu bar
Yes!! That did the trick, just hit the enter button 
Sometimes it’s not obvious!
I was having trouble with my pattern piece selection too, so your answer has helped me. thank you.
