What’s New in V5R19?
Student Notes:
The list of enhanced functions in CATIA Generative Sheetmetal Design V5R19 is given below: Enhancements in Extrusion: You can now avoid the degeneration of a curve. An error message will be displayed while creating an extrusion with the Automatic Bend option. Also you will see the enhancements to Explode Mode for the following cases: When the extrusion connects with the sheetmetal part When the extrusion does not connect with the sheet metal part Creation of constraints Generation of Sketches Enhancements in Recognize: You can now recognize stamps created on bends and forcibly recognize features other than stiffening ribs and curve stamps. Integration of Unfolded Curve in Drawing: Using the Unfolded View function from the Drafting workbench you can now generate the characteristic axis of a stamp in a drawing.

Generative Sheet Metal Design Student Notes:
Automatic Bend Enhancement (1/2) The following enhancement has been done in the Automatic Bend option of the Extrusion function: If there is a degeneration of curve element for extrusion profile, an error is displayed. (1/2) Extrusion sketch at extreme position: Degeneration of the curve element occurs if the radius of the curve element is less than or equal to the sheetmetal thickness and the Extrusion direction is towards center of the curve element.
The highlighted corner in the sketch has the radius equal to the thickness which is defined in the Sheet Metal Parameter.

Explode Mode Enhancements
Student Notes:
There are four enhancements in the Explode mode option of the Extrusion function which are as follows: Connected Extrusion’s Explode: The result will depend upon the type of sketch element which is connected to the part. If the connected part is: A line – the result will be a Tangent Wall on Edge. A curve – the result will be a Sub-Extrusion. A line followed by sharp vertex (or circular curve and line) – the result will be a Wall on Edge with Bend. A circular curve followed by line and the extrusion is created with limit types as dimension – the result will be a Wall on Edge with Bend. A circular curve followed by line and extrusion and is created with limit types as ‘up to plane’ / ‘up to surface’ – the result will be a Sub-Extrusion. Disconnected Extrusion’s Explode: The result will depend upon the fixed geometry. If it is located at the profile extremity and on the:

Generative Sheet Metal Design Student Notes:
Recognition of Stamps on Bends The following enhancement has been done in the Recognize function: Stamps on Bends: The aim of this enhancement is to suppress the limitation that forces the recognized stamps to have a single and planar support. The only multi-support stamps which will be recognized are those which are impacting one or several cylindrical bends.
Copyright DASSAULT SYSTEMES
Forced faces: All stamps are not automatically recognized because of the confusion they can create with a combination of walls and bends. Hence you have to force the faces to be recognized as stamps. Stiffening ribs and curve stamps which are perpendicular to the bend’s axis are natively recognized. If there is a planar face in the stamp which is not a stiffening rib then it must be forcibly recognized. The preview enables you to visualize which faces are recognized.

Unfolded Curve Enhancement
Student Notes:
The following enhancement has been done in the ‘Point or curve mapping’ function: A combo-box is added in the ‘Point or curve mapping’ dialog box. When creating an Unfolded Curve you can specify if the feature is a construction element or forms part of the sheet metal process. The default is a construction element. The four possibilities are as follows: Construction Element: The unfolded curve is used for intermediary construction and not needed for the laser process or for the drawing. This curve will never appear in the unfolded view of the drawing. Characteristic Element: This curve needs to be dimensioned in the drawing but is not required for the laser process. The curve will appear in the drawing if defined as visible in the Standards. Marking: This curve will appear in the drawing if defined as visible in the Standards. Engraving: This curve will appear in the drawing if defined as visible in the Standards.
