You can enter direct mathematical values and operators, variables you have created, and Visual Basic key words, such as Mod, Exp, or Log. For example, if you want to set up a plaster deduction of 3 percent, and you have defined a variable called Plaster_Deduction with a value of 0.97, enter AreaValue * Plaster_Deduction. NOTE It is important to enter the variable names AreaValue and PerimeterValue exactly as they are displayed in the Data field. Alternative spellings such as "Area Value" or "perimetervalue" are not recognized. 7 To test your formula, enter a sample value for Input, press ENTER, and check the result for Output. 8 Click OK. Attaching Notes and Files to a Calculation Modifier Style Use this procedure to enter notes and attach reference files to a calculation modifier style. You can also edit reference files attached to the style. 1 Click Format menu ➤ Style Manager. 2 Expand Documentation Objects, and expand Calculation Modifier Styles. 3 Select the modifier to which you want to attach notes or files. 4 Click the General tab. 5 To add a description to the modifier, enter it for Description. 6 Click Notes. 7 To add a note, click the Notes tab, and enter the note. 8 Click the Reference Docs tab, and attach, edit, or detach a reference file: If you want to... attach a reference file Then... click Add, select a file, and click Open. edit the description of a reference file select the file, and click Edit.

Setting Calculation Cut Planes for 3D Freeform Spaces Use this procedure to set calculation either or both of the cut planes available for 3D freeform spaces. These can be useful for rooms under a roof where the space area can be calculated only for the parts of a space with a specific height. Calculation planes can be automatically scheduled. 1 Select the spaces for which you want to define the 2 calculation cut planes, and double-click one of them. 2 Expand Basic, and expand Advanced Dimensions. 3 For Calculation plane height 1 and Calculation plane height 2, enter the desired values for the calculation cut plane height. TIP You can activate display components for the calculation cut planes and the calculation cut plane hatches in Plan view. For more information, see "Specifying the Display Properties of a Space Style" on page 1690. Space Decomposition In some countries, such as Germany and Japan, an important part of space evaluation is the visual decomposition of spaces into subdivisions for the proof that must be approved by the cognizant administrative authority.
