5.12.11.1.3.3. Manipulation of axes orientation (PARTproject) and part orientation (PARTdesigner)

During the modeling process in eCATALOGsolutions there are 2 methods available to manipulate the axis orientation and the position of the component in space:

  • Change the axis orientation: PARTproject -> Edit project -> General tab -> General -> Coordinate axes

  • Change the part orientation: PARTdesigner -> 3D history [3D History] -> Context menu component -> Rotate

    [Note]Note

    Dependencies are created when rotating [Rotate], so there may be no simple "back". When deleting automatically generated plans, the dependencies must be taken into account.

    A correct design of parts from scratch is always preferable!

Example

  1. Initial situation: In eCATALOGsolutions modeled component, "faulty" with Y-axis upwards.

    Request: The part shall retain its lying position within space, but the coordinate system shall get a new orientation with Z axis showing upwards.

  2. The coordinate system is realigned in PARTproject via the Coordinate axes function so that the Z-axis points upwards and the Y-axis points backwards.

    PARTprojectfunction "Coordinate axes [Coordinate axes] "

    PARTprojectfunction "Coordinate axes [Coordinate axes] "

    Result:

    [Note]Note

    Not only the coordinate system has been rotated, but the whole part.

  3. In PARTdesigner the component can be returned to its original position in space by rotating it [Rotate].

    The Rotate context menu command can be found at component level in the 3D history [3D History]. After applying +90 degrees around X, the component appears in its original position again. Compare Fig. „Initial situation“.

    [Note]Note

    The orientation of the coordinate system remains unaffected when using Rotate.

    [Note]Note

    The manipulation can be seen in the automatically generated plane ZX rotated 1.

    Dependencies are created when rotating [Rotate], so there may be no simple "back". When deleting automatically generated plans, the dependencies must be taken into account.

    A correct design of part from scratch is absolutely preferably!

    [Note]Note

    Restriction

    Rotate in PARTdesigner only works with fully modeled parts and not with Q&S parts.

    The alignment of Q&S parts can be manipulated in the project file. There is a string starting with REF1@MATRIX. In general: Calculate the rotation matrix and multiply the two matrices. There are help pages on the Internet for the calculation: http://danceswithcode.net/engineeringnotes/rotations_in_3d/demo3D/rotations_in_3d_tool.htmlor https://matrix.reshish.com/de/multiplication.php.

    The change is not in PARTdesigner but only in the PARTdataManager to see.
