Rules for the creation of Feature Variants for Plant Engineering parts
|
|
|
|
|
Saddle connection (Example) |
|
Elbolet (Example) |
|
D=Outer diameter of the nozzle, DA=Outer diameter of the part to which the connection is made, L=Length, S=Wall thickness |
||
Please note that the variable DA (Outer diameter) will be modified upon insertion. It will be applied to the outer diameter of the pipe to which the connection is made. This allows the calculation of the part geometry to match the respective fitting situation. Please check whether the geometry of the constructed saddle connection correctly adjust itself to a modified DA value.

If the variables names given in the Name column are used, you do not need to assign any attributes to them via the Variant Editor. If different variables are required, you need to assign the attributes given in the Attribute column.
VAA file
Use the Variant Editor to enter the suitable part type into the VAA file.
Then, use the Variant Editor to expand the VAA file in such a way that it contains values for the sizes specified here, and that the predefined attribute assignment is entered:
|
Parameter All dimensions must be specified in millimetres; |
Variable |
Assigned attribute |
|---|---|---|
|
Nominal diameter, Connection “!“and "2" |
N |
NENNWEITE |
|
Length |
L |
LAENGE |
|
|
||
|
Additionally (only if the corresponding standard uses nominal diameters in inches): |
||
|
Nominal diameter (inches), Connection “!“ and "2" |
NI |
N_INCH |
|
As only decimal values are saved to the VAA file as parameter values, nominal diameters in inches need to be entered as decimal values as well (e.g. 1.5 for 1 1/2‘‘). |
||
|
|
||
|
These parameters are to be considered for all connection types except for flange connections. For connecting sockets they refer to the pipe to be inserted: |
||
|
Outer diameter of the part to which the connection is made. This allows a suitable adjustment of the nozzle. |
DA |
D_AUSSEN |
|
Outer diameter, Connection "!" and “2“ |
D |
D2_AUSSEN |
|
Wall diameter, Connection “!“ and "2" |
S |
WANDDICKE |
If required, the attribute LAENGE needs to be assigned to the length variables (see Variables names above).
For variant synchronization you also need to enter the values for the attributes which are to apply to all sub-types of the variant.
Values must be entered for at least the following attributes:
|

ANSCHLUSSART
ANSCHLUSSART2 |
Connection type for Connection “!“(and “2“) If the same connection type is required at both part ends it will suffice to assign a value to the attribute ANSCHLUSSART. If different connection types are required at the part ends you need to assign the value of the connection type for Connection 1 to the attribute ANSCHLUSSART, and the connection type for Connection 2 to the attribute ANSCHLUSSART2. |
|||||||||||||||||||||||
|
Possible values of the attributes ANSCHLUSSART (CONNECTION_TYPE) and ANSCHLUSSART2 (CONNECTION_TYPE2):
The last character (x) provides information about the meaning of the supplement: 0 =No supplement 2 = The supplement consists of connection number, part type, ID, and standard of the part to be connected The prefixed connection number indicates the connection with which the auxiliary part is to be attached to the current connection.

Please also read the information given in the paragraphs
Important:
- When working with the HELiOS database, please pay attention to the correct classification matching the part type.
-
During variant synchronization the Nominal diameters in inches will initially only be taken over into the attribute N_INCH in the form of decimal numbers. The usual character strings for the specification of the nominal diameter in inches (e.g. 1 1/2‘‘ instead of 1.5) can be subsequently generated in the HELiOS database for the attribute NPS_INCH. For this purpose the HiCAD macro ANLDB_ZOLLATTRIGEN.MAC in the \HICAD\MAKROANL folder is used.
