3.1.6.4.8.1.  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. Special geometrical arrangements can also be used for the Partial Search.[53]

Process

  1. Load the reference part in the Part view and then call the Partial search.

    Call Partial search

    Call Partial search

    Call Partial search

    Call Partial search

    -> The respective dialog box is opened.

  2. With a single mouse-click, select one or more features.[54]

    [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 the front plane is sufficient, because it is very distinctive so that just with this single feature matching parts can be found.

    -> Selected features are marked with red.

    -> Deselection of a feature is done with repeated single-click.

    Plane selected

    Plane selected

    Just as well you can select such a feature in a more complex part.

    [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.

    Options for partial search:

    • Tolerance: Tolerance controls the maximally allowed difference between found part and search part.

      [Note] Note

      This parameter has considerable influence on the search speed. The smaller the value the quicker the search.

    • 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.

    • 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 hat 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.

Conclusion: Whether selecting the desired feature in a single part or in a more complex part doesn't matter.

[Note] Note

Depiction of search results

In the 3D tooltip, you can see which feature have been found.

If there is more than one group of features, you can switch between the results via buttons below.

When opening the part from the search results in the Part view, the first found group of features is selected.


[53] Before the Partial search can be used, it has to be made sure that under $CADENAS_SETUP/geomsearch.cfg, in the key PartialSearchCatalogs the catalog path to be used for the Partial search is inserted and afterwards the geometrical index is created/updated for the respective catalog (in toto).

Example:

PartialSearchCatalogs=cat/_partial_search

Several catalogs have to be entered separated by comma.

[54] It is not necessary to press Ctrl for multiple selection.
