Set Half

Use the Set Half tool to create a symmetrical image of a piece. This is a very powerful tool, which is used on almost every PDS file. When a piece is halved, all actions performed on the original half are applied to the other half. Unlike the Set Mirror Line Tool, you can work only on the 'real' half – and not on the 'reflected' half, which is represented as a grid of lines. Using Set Half is almost always preferable to using Mirror Half, mainly because Optitex 3D recognizes the halved pieces, and saves considerable time by allowing you to stitch only half of the stitches. Although we recommend keeping it in view, you can hide the reflected half through the View & Selection option.

Internal Objects Inside Half Piece

When adding an internal object (an internal contour, button, circle, etc.), it also appears on the reflected half, unless the Reflection field is disabled in the Internal Object Properties.
