This is the only functionality of the two keywords BlockBegin..BlockEnd, they are ignored by ODEON when a .par file is loaded. The keywords are automatically generated when a room is generated by ODEONExtrusionModeller or when a room is imported in the .dxf format. BeginBlock NumbOffSet 100 Pt 1 0 -1 0 Pt 2 0 1 0 Pt 3 1 1 0 Pt 4 1 -1 0 Surf 1 A surface 1 2 3 4 EndBlock Any code between a matching set of BlockBegin and BlockEnd's can be collopsed by clicking a small + in the left side of the editor, making it easier to handle large files, in particular with many layers. All blocks can be collapsed from the view menu in the ODEONEditor. And Blocks can be nested, that is, contain Blocks within Blocks. Defining constants Constants must follow the syntax: Const where value is a mathematical expression, which may be based on numbers or constants and variables that has already been defined. App-20
Example 1: Const CeilingHeight 3.4 Example 2: Const FloorLevel 1 Const CeilingHeight FloorLevel+3 Example 3: Const FloorHeight 1 Const Length 6 Const CeilingHeight FloorLevel+Length*TanD(30) Defining and reassigning variables The definition of variables must follow the syntax: Var Example 1; defining the variable FloorLevel: Var FloorLevel Example 2; defining the variable FloorLevel and assigning the initial value 0: Var FloorLevel 0 Example 3; reassigning a variable /adding 1 metre to the FloorLevel: FloorLevel FloorLevel+1 Remark: The predefined variable NumbOffSet may be used like any other variable, but has a special meaning because it offsets point and surface numbering. This variable is useful if copying a part of a geometry from another geometry file, it is also useful in connection with the for..end statements. Auto can also be assigned to NumbOffSet, in doing so ODEON will automatically increment the value of NumbOffSet to be greater than any point and surface number previously defined. This has the advantage that repeated point and surface numbers can easily be avoided without having to keep track on the numbers used - the drawback is that slight changes in the geometry file may change numbers on many subsequent surfaces, ruining the relationship between surface numbers and the material assigned to that surface inside the ODEON program. The Auto option is very useful in combination with loop constructions (see description of the for..end constructs later on). Typing PtAbsRef after the value assigned to NumbOffSet forces absolute number references for points while using the specified offset on the numbers of surfaces – this is explained later. Example on the use of NumbOffSet; creating surface 101 containing the points 101 to 104 and surface 201 containing the points 201 to 204: NumbOffSet.Par ### NumbOffSet 100 Pt 1 0 -1 0 Pt 2 0 1 0 Pt 3 1 1 0 Pt 4 1 -1 0 Surf 1 A surface 1 2 3 4 Z O NumbOffSet NumbOffSet+100 Pt 1 0 -1 1 Pt 2 0 1 1 X Y App-21
