Basic shapes of the LayoutEditor are path, box, polygon and text. There are several tools to convert between these shapes. These tool are located in the properties dialog of the shape. To convert a set of shapes in one step there are convert feature located under mainmenu/utilities/convert utilities. These tools will convert all selected shapes in one step.
Selected polygons with a rectangular shape are converted to a box. Are other shapes are untouched.
Pathes, boxes and text element are converted a polygons. A conversion of pathes and text elements is only possible in the case a width is set to these elements. The appearance will not change. This feature is very useful to make text visible in mask design, as text is often ignored in the photo mask fabrication.
Selected box and polygon elements are converted to a circle. The circle is fitted best possible in the existing points. The circle angle resolution from the setup dialog is used for the resulting circle.
Selected boxes, polygons and pathes are converted to pathes with its outline. Holes in polygons will get separate path.
Selected paths will be spitted into a single paths for each path segment. So it is an inverse function of a path merge.
All selected path elements having identical start and end point are converted to a polygon. All other pathes are not changed. If you have separate path elements for the edge use the draw/merge feature before the convertion to polygon.
