Using the Shape Colours Tab
This tab is used to control the colour and visibility of shapes; text callouts and shapes.
When a technology file is used with a symbol design, the symbol shapes colour is transferred to the shapes row, because this is consistent with their final use in a schematic design. Similarly for Doc. Sym. Shapes colours when editing a documentation symbol. The Sym. Shapes and Doc. Sym. Shapes rows are removed when editing a symbol. The same applies to Sym. Callouts.
