3.1.6.4.9.2.  Partial search: The most important at a glance
Description of function

The Partial search is a geometrical search. However, not parts are used as reference, but individual features such as plane, cylinder, etc. And then parts containing these features are found. The geometrical arrangement of features is also taken into account.

Process example using PARTdataManager
  1. Load the reference part in the Part view and then call the Partial search.

    Call Partial search

    Call Partial search

    Alternatively, you can find the command to call the partial search in the index tree at each part in the context menu.

    -> The respective dialog box is opened and the respective part is displayed in the Preview.

  2. With a single mouse-click, select one or more features. For deselection use a single click.

    4 features chosen

    4 features chosen

    The number of selected features is displayed below the preview. With Remove selection, you can remove all selected features at once.

    [Note] Note

    Always features of the same type (plane, cylinder, etc.) are compared. Distinctive and special features should be selected. A simple rectangular plane for example can be found nearly everywhere and expands the search space unnecessarily.

    In the example in hand, 4 features are selected, 2 cylinders and 2 planes.

    -> Selected features are marked with color.

    [Note] Note

    If there is no selection, then all features are taken into account, which may lead to a considerable (exponential) increase of search time.

    Settings Search template:

    • Use all parameters of selected elements: Default

    • Ignore cylinder lengths:When looking for a fitting counterpart for a hole or a pin, it may be advantageous not to include the length attribute for the search. In such a case use the search template Ignore cylinder lengths.

      Also see Section 3.1.6.4.9.4.6, “ Partial search: Ignore cylinder lengths ”.

    Options for partial search:

    • Accuracy: Accuracy controls whether a variance is allowed between found part and search part at all or how large it may be. Accuracy is a mixture between size and shape.

      [Note] Note

      This parameter has considerable influence on the search speed. Using Accurate the search speed is highest, using Rough lowest.

      When using the option Rough, you won't loose any possible results. May be Rough will provide some useful parts in addition.

    • Negative part:

      If activated negative parts are searched. For example, if an inner cylinder is selected, an outer cylinder is searched. In this way a bolt fitting into a hole could be found.

      Example:

      Also see Section 3.1.6.4.9.4.4, “ Partial search : Search for negative parts” or 1.

    • Inner contours:

      The outer contour is always considered at planes. When activating Inner contours these are considered in addition. That means for example, only those parts are found where the same number of holes is given and where the inner contours are similar, that for each contour in the search part an equivalent has to be found.

  3. Click on Commit.

    Commit

    Takes over all changes and closes the dialog box.

    Start Partial search via Start search.

    Commit and Search

    Closes the dialog box and starts Partial search immediately.

    Cancel

    Closes the dialog box without saving any changes.

    -> The view switches to Part view again.

    -> The Partial search is activated and a small preview image is displayed.

  4. Click on Start search.

    -> All parts containing the selected feature are found.

  5. At result parts worth to be considering, open the 3D tooltip.

    Here you can see which features have been found. They are marked in color.

    If there are several feature hits in the same result part, arrow keys are displayed enabling to click through the results.

    When opening the part in the Part view, the first found feature group is selected.
