The Extract the cut line, graded in a new piece function allows you to create a new piece from the piece built on the seam line and seam allowance set in Edit seam allowance.
This function displays the following options:
Extract to cut line – you can create a new main piece, extracting the cut line;
Extract to cut line with seam line attached– you can create a new main piece, extracting the cut line and maintaining the seam line as an attached piece.
The grading rules of the newly-created piece’s points are the same as the ones of the corresponding points from the source piece.
