Symbol component levels

The Level of the Symbol's original items determines the drawing order of the components.

To get an overlapping effect with two or more symbols, take some time to think about the Level of the Polygon items you create.

TIP: Using Polygon items (or Bitmap items) is especially useful for symbols that stand out (eg for Command and Control type applications).

When symbols are drawn on Points, the levels are added together. Cadcorp SIS Desktop will only draw levels between 0 and 255. If the total of the levels is greater than 255, the symbol will not be drawn.

Note: When tallying the total level number, each individual layer of the Symbol is taken into account.

Look at these examples:

TIP: We recommend setting a low level to items making a symbol. This avoids the possibility of all or part of the symbol not being displayed as shown above.
