3.5.3. Characteristics

In the following the characteristics / modeling rules will be described for each target system:

All systems

  • The parts must be located with the Z-axis to the top and with the Y-axis to the front (left in the isometric view)

  • The parts require the Placement Classification (see Section 5.17.2.4, “ Published element - Choose connection point ”)

  • The parts should be equipped with a changeable Level of Detail (also see below)

  • If possible it should be worked with regular bodies / simple shapes.

[Note] Note

The regular bodies concept has been discarded almost in the meantime – this means it is no longer required to model strictly with such bodies. Anyway, it is recommended to “think simple” while modeling and leave out all kind of cosmetics and complex constructions.

Revit

  • Parts must be classified with CADENAS Revit classification (family template, placement information and other attributes) and „OmniClass 2006“ (on this see separate point Classification below).

  • It is not allowed to use features / radius smaller than 1.4 mm in modeling.

  • Use extrusion features and avoid rotation features - if possible.

  • Cut-rotations (e.g. chamfers) should also consider the 1.4mm tolerance

  • All kind of conductors, pipes, channels, etc. have to be modeled as “filled body” absolutely.

  • A Revit connection point (Revit Family Template Mapping) must be specified (please also see separate point Classification below).

    For the placement in Revit, the axes of the connection point will be used for positioning /orientation. Take care that axes orientation of the point is according to the axes in Revit (Z axis corresponds to orientation).

  • Revit connection points always have to be in the geometric center of gravity of a planar surface. Please also regard the orientation (Z axis) absolutely.

    [Note] Note

    Also check existing examples – please request them by sending a short e-mail to catalogs@cadenas.de.

ARCHICAD

  • The parts must be classified with IFC.

  • Parts must be equipped with the CADENAS - ARCHICAD classification. This classification covers objects / categories such as Door / Window, which can be described more detailed by attributes.

IFC

  • The parts must be classified with IFC.

    (See separate point Classification below.)

  • Use extrusion features – Avoid rotation features - if possible.

  • Absolutely avoid cut of edges (single edges should not touch each other):

  • It is not allowed to subtract volumina more than 1 time (cut features should not touch each other).

  • All parts should be tested with the “IfcCheckingTool”, see Further tests below.
