Figure lb. Positioning of building elements with TachyCAD
and tacheometer
The different modifiers defined in ADT and usable with
Palladio X5 can also be used with the tacheometer. The ability
to adapt standardised building elements (e.g. walls) to their
actual object geometry is essential in order to able to model
existing buildings with all irregularities within an object-
oriented system (fig 2).

Figure 3a. Sketch model
Palladio can also be used as a first stage for sketching out a
rough building model (fig. 3a) which can then be ‘intensified’
using surveying methods to develop as precise and detailed a
3D-model (fig. 3b). This combination means that it can be used
as surveying tool at both a simple and highly detailed level. A
high density of information can be employed selectively
throughout the entire process.
Figure. 3b. Extended and intensified detail model
The retrieval and allocation of further information to or from
building elements can be undertaken using the resulting CAAD-
model. Standard information retrieval methods in Palladio
include room stamps and lists of building element (Fig. 4).
Additional modules allow surface and volume quantities to be
calculated for later use in specification of conservation works.

measurements - screenshot
Measurements provided by the tacheometer adapt the standard
CAAD wall element to the actual surface form with the help of
so-called modifiers (fig.2b).

This approach allows the typical 2D-geometric building survey
to be expanded into a quantifiable building-element related 3D-
