The Welding tool in our Vision PRO engraving tool is one you should become familiar with. It easily deletes overlapping vectors (lines) giving you a cleaner engraving. For example, when engraving script fonts, the lines of the letters may overlap. By highlighting the text and clicking the WELDING ICON you eliminate the overlapping lines. It is also very useful if you want to combine two shapes. You can select any two overlapping objects, and combine them into one shape just by clicking the WELDING ICON.
