ACIS에서 인식되는 Feature


  • Holes (cylindrical, conical, spherical and toroidal): Holes that are split along or across axis due to interaction with other features are recognized as a single hole only if they are completely overlapping along their axis. Partial overlap holes are not recognized as a single hole feature. Filleted holes are recognized as toroidal holes and not as a hole and a fillet. Partial spherical holes where the angle of wrap is less than 360 are not recognized. If a spherical hole is cut, it is recognized only if the cut is normal to the axis. Partial holes and bosses are not supported.
  • Chamfers
  • Blends (constant radius and variable radius): Constant radius as well as variable radius blends are supported. Blend chains are recognized as single features.

    • The bodies passed into the defeaturing API must be manifold.
    • Although the defeaturing API recognizes blends whose faces have been split, currently these blends cannot be removed. Refer to the following figure for an example of a blend with a split face.
