Floors are now all relative to the lowest floor and controlled by the floor to floor height. Floor to floor is obviously the important controlling dimension for all of us.
In AECOsim Building Designer SS6 Update 1 (08.11.09.866) we have enhanced the Floor Manager interface to clarify and simplify it's use. The previous content for SS6 (08.11.09.829) is included lower down the page for reference.
In this version three values can be input into the Floor Manager table:
If Relative Elevation is 0.00 the Relative Elevation column will match the Elevation column and can be ignored.
If a relative elevation is entered the Relative Elevation column will be populated with values calculated relative to the 0.00 Elevation value. In the example below the Ground Floor Elevation is set to 0.00 to clearly demonstrate this (the 0.00 value will be used regardless of whether it is actually displayed as one of the floor elevation values).
The elevation column is populated by values calculated from the lowest floor level and the floor to floor values:
Floor to floor values control the floor heights, their actual and relative elevations are calculated and displayed alongside:
Floor Manager now includes an Insert Floor tool that allows new floors to be inserted in the list updating floors above:
The same inputs were available in the initial SS6 release where it worked as shown in the following section:
Using the GB Dataset - for Building01 (as delivered) 'Use Relative Elevation' is unticked, then enter the level of the lowest floor and floor heights for each floor starting from the lowest floor. Elevations and Relative Heights are identical.
Floor to floor heights for each floor can then be used to control floor heights with the elevations being calculated accordingly.
Building02 turns on ‘Use Relative Elevation’.
Setting up the floors is the same but the relative elevations are calculated using the offset, the offset value needs to be calculated appropriately depending on the height datum being used before entering it into the dialog.
Note that the offset is relative to 0, so in this example setting Floor 00 to 0 and adding the site datum of 40000 to the height of Floor 00 above the datum the Relative Offset value required to show Floor 00 as 0 is 41500:
as shown in this sketch:
Alternatively, use the site datum of 40000 as the Relative Offset then set B2 to -6500 resulting in Floor 00 having an elevation of 1500. The Relative Elevation of 41500 is the same but the floor heights are expressed treating the site datum as zero.
