Shrinkage Compensation for Profile

During welding or cooling in a real yard scenario, steel would shrink. To compensate for shrinkage, individual manufacturing features, consider shrinkage amounts.

  1. Apply Shrinkage to Profile Outer Contour - For a profile outer contour Shrinkage Compensation (SC), you must create a margin as the shrinkage type. Change the type to Shrinkage after the margin feature creation. The value in the Size column is editable.

  2. Apply Shrinkage to Profile Mfg Features - After applying shrinkage compensation to a profile, you can update specific Mfg (Manufacturing) features for shrinkage compensation. Such as Opening, Attachment Line, and Reference Line.
    1. User Interface Change - to support shrinkage compensation of the features mentioned above, a column Offset is displayed if shrinkage is applied to profile outer contour.
    2. Apply Offset to Profile Mfg Features - When the offset value is defined, the Mfg feature that you selected is updated with the offset value.

      In this scenario, the offset value is 10mm, so the opening feature moves for offset from the origin (1-Start) to the profile start to end (2) direction.

    3. Offset Value Initialization - If the last margin features as the shrinkage type is removed or changed to an Applied type, a warning message window is shown. Selecting OK, the offset value of each Mfg feature is initialized. Otherwise, no changes occur.
  3. Profile XML Extraction - After applying profile shrinkage, the margin element in XML has one more attribute as type if the margin type is Shrinkage. The features update with an offset for shrinkage compensation and they extract with the existing format.
