Manual BMG Layer (DIN4003)

Drawings can be enhanced with BMG layers according to DIN 4003. When exporting 2D DXF/DWG these layers transfer important information for Tooling and BIM, among others.

Precondition: CNS classification with respective data

  1. In PARTdesigner, in the docking window 3D History, click on the context menu command New 2D drawing....

    -> The dialog box 2D drawing is opened.

    Dialog box "New 2D drawing"

    Dialog box "New 2D drawing"

  2. Under View, select the option User.

    Under Name, for example, enter BMG.

    Under Layer group, select the option BMG.

    Confirm with OK.

    -> The Sketcher is opened. (The button group Text is visible for drawings.)

  3. In the Sketcher, create your drawing as usual.

    [Note] Note

    A 2db file can also be saved and loaded as parametric 2D sketch.

  4. In order to classify drawing elements mark a line and click on the icon Classify element .

    In the dialog box Change parameter, select desired Group (here Tool name) and Classification (Layer).

  5. With Hide classified elements. , you can hide or show all layers of a group or single layer and check in the way, if everything has been set correctly.

    Click on the button.

    -> The respective dialog area is opened.

    All layers hidden except for "NC-Geometries"

    All layers hidden except for "NC-Geometries"

    Activate/deactivate the checkbox at desired groups or layers.

    Currently all lines are displayed in black.

    Line thickness can be thick or thin. Options for Line type are solid, dashed, dashed/dotted and double dashed/dotted.

    Depending on layer, the lines are shown thick or thin. Detailed information on the single layers can be found in the specification DIN SPEC 69874-2.

  6. In the Sketcher, finally click Accept changes.

    -> The layer is shown in the 3D History.

  7. Under PARTproject -> Edit project -> tabbed page 2D derivation, determine that the 2D sketch is displayed.

    • Under View, enter the display name.

    • Add 2D model. For this you have two options:

      • Select From 3db file, if you created the drawing in the sketcher.

      • Select a 2db file, which is stored in project directory.

    • In the third column, select option Add.

  8. In PARTdataManager, the additional drawing is shown under Technical details .
