Find the Incorrect Point of the Part Model

General

  • This instruction is suitable for situations where Acis errors are revealed in the modeled part.
  • The part model errors can be revealed by the following functions:
    • In keyboard functions Shift C.
    • In the part model’s context-sensitive function ACIS geometry > Check.
    • In the part model’s context-sensitive function ACIS geometry > Healing.
    • In the function Part | Tools | Analyze.
    • In the function Assembly | Tools | Analyze.
    • When you select the history indicator and the context sensitive function Start and run through the history of the model by selecting the history indicator and the context-sensitive function End.
      • The features that fail are displayed in red in the feature tree.
      • A feature before the red feature has been created differently than before and causes errors in the model.

Find the Feature That Causes Errors in the Part Model's History Tree

  1. Perform an analysis of the part model by using one of the above methods, for example the context-sensitive function ACIS Geometry > Check.
  2. In the feature tree of the part model, drag the history indicator to the middle of the feature list, for example, or
    • Click on a feature in the middle of the list and select the context-sensitive function Roll history.
    • The program modifies the model so that only the features that were created before the history indicator are visible.
  3. Perform the part model analysis again.
  4. Depending on the result of the analysis
    • Errors still exist: Drag the history indicator to the middle of the features that are still visible.
    • No errors found: Drag the history indicator to the middle of the hidden features.
  5. Perform the part model analysis again.
  6. Continue iterating the incorrect feature by repeating steps 4...5.
  7. When you find an incorrect history step
    • View the sketch of the feature and change it slightly if possible.
      • A sketch whose geometry is not fully defined by constraints can, when varying the dimensions of the model or running through the history of the model, change in such a way that a decent geometry is no longer created as a result.
    • View the feature operation and change it slightly if possible.
  8. Perform the part model analysis.
  9. Select the history indicator and the context-sensitive function End or
    • drag the history indicator towards the end of the feature tree if you suspect that there are other Acis errors in the part model
    • And reanalyze the model.
