Adjusting sketch

Hi there! I just designed a chair in shapr. My first time and it works smooth!
I´d like to export parts of the sketch to create an SVG file for shaper origin. I made adjustments so the sketch isn´t correct anymore.

What´s the best way to go to adjust that sketch to the model?

Thanks in advance!

Best regards
