Pipe Accessories

Pipe accessories, such as valves must follow the VDI 3805 sheet #2 guideline. The sheet 2 guideline cannot be fully repeated due to copyright, but these are some key facts:

The geometry must have its 0/0/0 (X/Y/Z coordinate) point at the position where the center of the pipe intersects with the position of the valve.
The geometry must follow the rule-based concept (in every case for LOG 200/300)
A placement connection point (Revit) must be available and positioned at 0/0/0 with Z-Axis pointing down (see above (Placement (Revit))
Connection points (for Piping) must follow the rules above:
- placed at accurate position (ideally at center of plane surface)
- local Z-axis (flat side of the "pyramid") pointing into “pipe-direction”
- local Y-axis pointing upwards (relatively to the part)
Pumps with different LOG (see Section 3.5.2.3, “LOG (formerly called "LOD")”)

Doors

Doors with different LOG (see Section 3.5.2.3, “LOG (formerly called "LOD")”)

Doors (and windows) are very special and complex objects in buildings. In general, doors and windows should be modelled as parametric geometries (in all AEC-CADs). As CADENAS does not export parametric CAD objects, the following parameters for doors are mandatory.

Wall thickness – incl. plaster (as the door frame cannot react to the wall-thickness)
Wall opening width and height (must be wider and higher than the door leaf width/height because of mounting spaces) Common values for added spacing are: +35mm width and +17.5mm height. These values must be worked out and finalized with the manufacturer in the project workshop.
