To Define Calculation Settings and Calculation Standard

Note: This topic is for Roombook users only.
Roombook includes country-specific calculation standards:
  1. Click Vision Tools tab Roombook panel Calculation Settings.
  2. Click Change to modify the standard.
  3. Define the settings.
  4. Click OK.

Now, the defined calculation standard is set current and will be used for the next room quantity calculation.

Calculation Standard

In this field is shown the current calculation standard. In order to change it, click Change.

The settings are stored in the current drawing. In new drawings, the default setting is applied until changed.

International
The International Standard calculates the real quantities.
Sub areas
Optionally, some objects can be considered or not as sub areas (Yes/No toggle):
  • Consider interferences as sub areas
  • Consider body modifiers as sub areas
Those objects can optionally be listed and calculated as sub areas.
VOB Standard
The German VOB standard defines a specified set of rules for the calculation of room quantities.
Sub areas
Optionally, some objects can be considered or not as sub areas (Yes/No toggle):
  • Consider interferences as sub areas
  • Consider body modifiers as sub areas
Those objects can optionally be listed and calculated as sub areas.
VOB
Depending on which trade the quantities are calculated for, there are different rules for subtracting sub areas.

For example: Sub areas like openings, windows, doors up to a size of 2.5 m² shall be ignored for calculating wall surfaces. For sub areas in floor and ceiling surfaces shall be applied a size limit of 0.10 m².

Wall Opening
By default, the option is activated with a value of 2.5 m². In this way, openings in walls up to this size are ignored. All openings which are larger, are calculated.
Floor and Ceiling Openings
By default, the option is activated with a value of 0.10 m². In this way, openings in floors and ceilings up to this size are ignored. All openings which are larger, are calculated.
Change Values
You can at any time change the calculation settings, by simply entering another value in the edit field. The following room quantity calculation is performed with the current calculation setting. In this way, you can calculate the room quantities according to VOB by trades.
Exceptions to the Rules
Of course, you can define exceptions to the rule, that means to calculate individual openings regardless of their size. Those individual changes can be done in calculated Room Quantity Sub Areas dialog box, by clicking VOB Calc. If you don't want to perform a VOB-conform quantity calculation, but instead want to calculate the real quantities, you can simply set the two options to "Ignore Openings: No". In this way, all openings regardless of their size are calculated.
Set as Default for New Drawings
When you changed the values, and want to use those further in new drawings, activate this checkmark. In this case, the settings, as delivered by the program, are changed and your values are taken as default.
Restore Defaults
With this button you can quickly restore the default settings.
