Le opzioni di visualizzazione controllano come gli oggetti sono visualizzati in generale: color and layout of lines, font of numbering, and so on. In the "View" navigator, however, you can decide whether specific objects are shown or not.
Select the relevant object in the "Category" tree. You can then adjust the color, line type, font of numbering, and so on, in the "Parameters" section. The parameters depend on the selected item.
As the settings are managed separately for the "Screen" and "Printer," you can make specific adjustments for the work window and for your documentation.
