Symbols are used to define a map object’s graphic appearance (characteristic). For example, a tree is represented by a green point on the map. Every map object drawn using the “tree” symbol will therefore have the same graphic appearance. If the symbol is changed using the symbol editor, all map objects drawn using it are also changed. OCAD provides four basic symbol types that correspond to the properties of the respective objects:
Choose this command to create a new symbol. The New Symbol dialog box is displayed. Check the desired symbol type and click OK. A dialog box is shown where the parameters of the symbol can be defined, varying according to the symbol type.
For basic principles see Create a New Symbol.
- Point symbol: Symbol for point objects.
- Line symbol: Symbol for line objects.
- Area symbol: Symbol for area objects.
- Text symbol: Symbol for text.
- Line text symbol: Line text symbols are used for text along curved lines.
- Rectangle symbols: Symbol for rectangular frames.
Choose this command from the Symbol menu or click with the right mouse button on a symbol in the symbol box to edit the currently selected symbol. According to the symbol type a dialog box is displayed where the symbol properties can be modified:
- Edit Point Symbols
- Edit Line Symbols
- Edit Area Symbols
- Edit Text Symbols
- Edit Line Text Symbols
- Edit Rectangle Symbols
Choose this command from the Symbol menu or click with the right mouse button on a symbol in the symbol box to draw or edit the icon for the selected symbol. The Edit Icon dialog box appears, which contains a simple paint program to draw an icon.
Learn more about the Icon Editor on the Icon Editor page.
Choose this command in the Symbol menu to enlarge or reduce the selected symbol(s) or all symbols. The Enlarge Symbol dialog appears.
Enter here a percentage value to enlarge or reduce the symbol(s). A value of 100 means that the size of the symbol remains the same. A value smaller than 100 means the size of the symbol is reduced, a value greater than 100 means the size of the symbol is enlarged.
If this check box is checked, all symbols are enlarged/reduced. If it is not checked, only the selected symbol(s) are enlarged/reduced.
This function is disabled for course setting projects.
Choose this command from the Symbol menu to copy the selected symbol(s) to the clipboard.
If a symbol has been copied to the clipboard, choose Paste from the Symbol menu to paste it either to the symbol box of the original map or to the symbol box of a different map. Keep in mind that when you copy a symbol to a different map, the colors are not copied. Read how to copy objects and symbols from one map to another here.
This command is activated if the clipboard contains one or more OCAD symbols.
Choose this command to paste a symbol or a group of symbols from the clipboard to the current map. If a symbol number already exists, it is changed to the next free number. Use the Copy function from the Symbol menu to copy symbols to the clipboard.
Choose this command from the Symbol menu to delete the selected symbol(s). A confirmation message appears before the symbols are removed from the symbol box.
If a deleted symbol is used in the map, the respective objects are not deleted, but appear gray as Unsymbolized Objects.
Choose this command from the Symbol menu to duplicate (create a copy of) the selected symbol(s). The duplicated symbols get the next free symbol number.
If one symbol is selected, the duplicated symbol is inserted after the selected symbol; otherwise the duplicated symbols are appended at the end of the symbol box.
You can sort the symbol box by various definition.
- By Symbol Number
- By Color
- By Symbol Type
- By Status (Normal, Protected or Hidden)
- By Usage Frequency
Learn more about sorting the symbol box on the Symbol Box page.
It's possible to select objects without specially clicking on them.
