9.8.1. Create dummy starter part

In assemblies, the selection of certain characteristics does not happen via tables of single parts, but via a superordinated table, which is in the so-called dummy starter part.

As a basis for this superordinated table (the later assembly table) use the table of a significant single part. Here in this example this is the table of a wing. The variables of the bolt will be brought into dependency to the variables of the wing, so that they don't have to be part of the assembly table explicitly.

The table also contains variables only used by the assembly, which do control functional characteristics like angularity or rod position, for example. Here in this example this is the angularity of the hinge. And this table is the actual assembly table.

The dummy starter part is a 3D project (single part) WITHOUT GEOMETRY (without features), it serves as "Starter part", and contains ONE! Connection point for the actual assembly and is not not exported.

  1. Create a dummy starter part as new project "hinge_dummy" with Template for 3D project.

    Call "New project"

    Call "New project"

    Dialog box "New project"

    Dialog box "New project"

  2. Mark the file "wing.tac" in "wing.prj" and under Edit project -> Table file, click on Edit.

    -> PARTdesigner is opened. Save the file as "hinge_dummy.tab or .tac". (Confirm with "Yes" - if the query "Replace?" pops up.)

    In PARTproject, make sure that the file "hinge_dummy.tab" is selected in the list field under Edit project -> General -> General -> Table file.

    [Note] Note

    The table hinge_dummy.tab will be visible in the assembly later.

    Table "hinge_dummy.tab"

    Table "hinge_dummy.tab"

  3. In PARTproject, mark the file "hinge_dummy.tab" and in the docking window Edit project, click on Edit.

    -> PARTdesigner is opened.

    Add a variable ANG to control the angularity of the hinge.

    Add variable "ANG"

    Add variable "ANG"

    Here in this example following settings are made:

    • Save location: Currently just Only in table is available. At the latest when setting the connection point, In geometry and table has to be set.

    • Identification type: Choose Function attribute.

    • Status: Select Value range variable. Under "ANG", the opening angle of the hinge can be inserted.

    • Equation: Choose an opening angle of the hinge (e.g. 0 to 150 degrees).

      [0:150]

    Adjust the standard name.

    NB='Hinge $L.$ANG.'

    Adjust standard name

    Adjust standard name

    [Note] Note

    The table file had been copied from "wing.prj".

    As this table is used for the assembly table project the options "Standard Number", "Standard title", "Standard name" and "BOM name" have to be adjusted accordingly.

    You must be careful with Standard name that the name of the assembly becomes clear! In our example, the name is distinguished by the use of $L. and $ANG.

    The BOM name corresponds to the standard name (in this example).

  4. Open "hinge_dummy.3db" and add the Connection point for the actual assemblies.

    Accept the changes and save the file.

    [Note] Note

    The file only contains the connection point and no geometry.

    Set connection point
