5.11. Specify automatically created dimensionings (notations) for 3D view and 2D derivation

For Part selection in PARTdataManager, dimensionings are automatically created in 3D view and 2D derivation. When exporting the part, the 2D derivation is transferred to the CAD system.

During modelling process respective data is parametrically created in PARTdataManager in the dialog area Dimensions. Certain dimensions can be configured in a way that end users can click them and thus select alternative characteristics.

  • At first set needed dimensioning points - if not available yet

    Since the measuring points reference to dimensioning points/connection points, they must either already be available within the part or specifically set.

    Connection points may be used just the same as Dimensioning points.

    Absolutely, please regard on which face/plane the Dimensioning points are set!

    If dimensioning points are not set correctly, dimensionings are shown like they were pointing to a wrong place in the 3D view, when setting option Perspective projection is selected.

    The dimensioning points should be moved to the nearest position in direction of viewer.

  • File for saving the dimensioning parameters

    If there is no file for saving the dimensioning parameters available yet, in the project, a file same-named to the project *.dim is automatically created and the key CUSTOMDIMENSIONSV9 in the Assembly Configuration project file (*asmcfg.prj), Assembly Template project file (*asmsbl.prj) or Single Part project file (*.prj) points to this *.dim.

    If a file customdimensions.txt still exists from earlier versions, it will be used further on and data is read and saved from there.

    In both cases you don't have to interact manually.

Special notes:

Do not use translations for automatic dimensioning! [40]Use instead a Value range variable with naming with neutral text.

  • Working area is the docking window Dimensions. It is subdivided in two dialog areas:

    In the upper dialog area, all dimensionings are listed with their description (ideally identical to the variable name such as L, R, D, etc.), in the lower area, the particular parameters of the selected dimensioning.

    When selecting a dimensioning, the respective view in the 3D view is marked in green, Start point and End point in red. Vice versa, when selecting a dimensioning in the 3D view, the respective line is marked on the right side.

    • Dark gray background

      The dimensioning currently displayed in the 3D view

    • Red bold font

      The dimensioning has been changed. In this case an icon is displayed in addition.

    • Gray font color

      Gray font color is displayed in the following cases:

      • No view selected

      • Set condition, which the currently loaded part doesn't meet.

      • A dimensioning (e.g. distance, angle, etc.) is smaller than the set Accuracy.

  • As soon as all Mandatory parameters are set, the dimensioning is displayed in the 3D view.

  • As soon as all Mandatory parameters are set, the dimensioning is also displayed in the 2D derivation.

  • When selecting a dimensioning line, in the lower dialog area, all parameters of this dimensioning are listed, namely separated in Mandatory parameters, Optional parameters and 3D Parameter. Here, parameters can be set or changed. Changes become immediately visible in the 3D view (if the mandatory parameters are set).

    You can find detailed information on the mandatory parameters in the single chapters of the dimensioning types. Detailed information on the optional parameters can be found in an own chapter Section 5.11.7, “ Optional parameters Details ”.

  • Value changes are signalized, once at the parameter itself by an undo icon (when clicking on the icon the change is reversed) and once in the list of dimensionings by red bold font.

    The undo icon is displayed, as long as the change has not yet been saved by clicking on Save changes . After this undo is not possible anymore.

  • Above the listing of dimensionings the following buttons are shown:

    • Create new dimension

      -> A new dimensioning is added to the list. At first the Type HORIZONTAL is displayed. If needed, adjust the selection in the list field under "Type". You can adjust the Type anytime.

    • Duplicate dimension

      –> A copy of the dimensioning selected in the list is created.

    • Delete selected dimension

      –> The selected dimensioning is removed from the list. However, not until Save changes has been clicked, the deletion is complete and there is no "Undo" anymore.

    • Save changes

      –> Changes are saved in the file *.dim.

      As long as you do not click on the button Save changes , at the ID line above and at each changed parameter an icon is displayed. Clicking on the icon you can undo the respective action.

      If the changes have been saved no undo is possible anymore.

    • Show all

      All gray (inactive) lines are hidden. Compare ???.
