PrefaceThe V5 CATIA - Sheet Metal Production is a product offering an intuitive and flexible userinterface. It provides

Natively integrated, CATIA - Sheet Metal Production offers the same ease of use and userinterface consistency as all CATIA V5 applications.As a scalable product, CATIA Version 5 Sheet Metal Production can be used in cooperationwith other current or future companion products in the next CATIA generation such as CATIAVersion 5 SheetMetal Design and CATIA Version 5 Generative Drafting. The widest applicationportfolio in the industry is also accessible through interoperability with CATIA Solutions Version4 to enable support of the full product development process from initial concept to product inoperation.

Getting StartedBefore getting into the detailed instructions for using Version 5 CATIA - Sheet MetalProduction, the following tutorial provides a step-by-step scenario demonstrating how to usekey functionalities.

The main tasks proposed in this section are:

Entering The WorkbenchRecognizing Walls

Using Bending WizardUnfolding the Part

Checking OverlappingSaving As DXF

All together, these tasks should take about 15 minutes to complete.

Getting Started

Recognizing WallsThis task shows how to automatically create walls from an existing solid.

Click the Walls Recognition icon 1.

Select a surface as the reference wall.We selected the top surface.

2.

Walls and cutouts areautomatically generated.

Recognizing Walls


Sheet Metal parameters are alsocreated.

Double-click Sheet Metal Parameters inthe Specification Tree.The Sheet Metal Parameters dialog boxis displayed.

3.

Select the Bend Extremities tab andchoose Maximum.

4.

Click OK.5.

Recognizing Walls


Using the Bending WizardThis tasks shows how to automatically create bends from the generated walls.

Click the Bending Wizard icon .Bends are previewed.

1.

Bends that can be created are displayedin green, whereas bends where anambiguity arises are displayed in red.

The Auto Bend Definition dialog box isdisplayed indicating how manyambiguities have been detected, as wellas the number of Unconnected walls (i.e.walls not connected by bends), andOrphan walls.

Manually select the top edges as the bends tobe created.

2.

The Auto Bend Definition dialog box isupdated.

When no more ambiguity is identified, clickOK.

3.

Using the Bending Wizard


The bends are created and the specification treeupdated accordingly.



Unfolding the PartThis tasks shows how to unfold the part.

Click the Unfold icon .1.

The part is immediately unfolded.

To return to the 3D view, click the Unfold icon again.

Unfolding the Part


Checking OverlappingThis tasks shows how check the overlapping of different areas of the unfolded part.

Click the Check Overlapping icon .1.

In this case, a message is issuedindicating that no overlapping isdetected.

To find out more on overlaps, refer to Checking Overlapping.

Checking Overlapping


Saving As DXFThis tasks shows how save the generated geometry as a DXF document.

Click the SaveAs DXF icon

.

1.

TheSelect aDxf filedialogbox isdisplayedallowingyou tonavigateto thecorrectlocation.

Indicate the correct path and file name.2.

Click Save.3.

The geometry has been saved as a DXF type file.

Recognizing WallsThis task shows how to create a Sheet Metal part based on an existing solid.

Open the RecognizeWalls01.CATPart document from the samples directory.This document contains a part created in the Part Design workbench and looking like this:

Click the Walls Recognition icon .1.

Recognizing Walls

file:///E|/WWW/FmoCXR5/Sh1English/sh1ug.doc/src/sh1ugbt0100.htm (1 of 3) [10/3/2000 4:04:36 PM]

Click any face of the part as the reference wall.2.

Walls are automatically generated from thePart Design geometry.

Open the RecognizeWalls02.CATPart document fromthe samples directory.This part contains a filleted CATIA V4 solid presentingdifferent orientations.

Click the Walls Recognition icon .1.

Click any face of the part as the reference wall.2.

Walls and bends, due to the presence offillets in the initial part, are automaticallygenerated.

Recognizing Walls


Note that once the part has been transformed into Sheet Metal features, the Sheet MetalParameters are also created in the specification tree. Double-click to edit theseparameters.

Recognizing Walls


Using the Bending WizardThis task shows how to automatically create bends onto existing walls.

Open the BendingWizard01.CATPart document from the samples directory.

Click the Bending Wizard icon 1.

The bends are created.

Open the BendingWizard02.CATPart document from the samples directory.

Click the Bending Wizard icon 1.

The bends cannot be created as there is an ambiguity because too manybends would overlap.

The Auto Bend Definition dialog box isdisplayed indicating how manyinconsistencies have been detected, andthe number of walls not yet connectedby a bend (Unconnected walls).

Orphan are wall that are not connectedto any other wall.



Explicitly select the bends that should becreated. They are immediately previewed andthe dialog box reflects your selection.

2.

Click OK in the dialog box to create the bends. 3.



Checking OverlappingThis tasks shows how check the overlapping of different areas of the part. This is usuallydone when the part has been designed, bends created and the part is unfolded.Overlapping between areas of the part are highlighted.Open the Overlap01.CATPart document from the samples directory.

Click the Check Overlapping icon .1.

The area with the overlapping ishighlighted in red.

Unfold the part and repeat the check, as itoften is more obvious on an unfolded part.

2.

iClick Apply.A curve is generated. This curve can then be used to create a cutout, for example,to solve the overlapping.

3.

Click OK.4. When no overlapping is detected, a message isissued:



UnfoldingThis tasks shows how unfold/fold a part.

Open the Unfold1.CATPart document from the samples directory.

Click the Unfold icon .1.

Click the Unfold icon again to return to the view ofthe folded part.

2.

Unfolding


Saving As DXFThis tasks shows how save the generated geometry as a DXF document.

Click the SaveAs DXF icon

.

1.

TheSelect aDxf filedialogbox isdisplayedallowingyou tonavigateto thecorrectlocation.

Indicate the correct path and file name.2.

Click Save.3.

The geometry has been saved, and can be imported as a DXF file in any systemsupporting this type.Refer also to DXF Import/Export Format.
