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

Click OK to generate the walls, and bends if any.3.

Walls are automatically generated from thePart Design geometry.

Open the RecognizeWalls02.CATPart document from

the samples directory.This part contains a filleted CATIA V4 solid presentingdifferent orientations.

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.

Note that once the part has been transformed into Sheet Metal features, the Sheet Me

Parameters are also created in the specification tree.Double-click the Sheet Metal Parameters entry from the specification tree to see themThe Thickness parameter cannot be modified because it is based, like the bendextremities and radius, on the initial solid geometry . However you can modify theseparameters (bend radius and bend extremities) to be taken into account for sheet metfeatures other than the "recognized" ones.The bend allowance, being used to unfold the part, and the corner relief affect allfeatures, and therefore can be edited even for "recognized" features.

Uncheck the Generate Bends button, if you do not wish bends to be createdautomatically.

Recognizing Walls



22/39


This task shows how to automatically create bends onto existing walls.

Open the BendingWizard01.CATPartdocument from the samples directory.

Click the Bending Wizard icon1.

The bends are created.

Open the BendingWizard02.CATPartdocument from the samples directory.

Click the Bending Wizard icon1.

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

The Auto Bend Definition dialog box isdisplayed indicating how many

inconsistencies have been detected, andthe number of walls not yet connectedby a bend (Unconnected walls).

Orphan walls are walls that are notconnected to any other wall.

Checking Features

his sectiongives you tools to check the Sheet Metal Part prior to production:

Check overlapping: click the icon to highlight the overlapping areas, then click Apply to

create a curve.

Check bend radius: click the icon to generate the list of bends not using the default ben

radius parameter value.Check feature fold/unfold visibility: click the icon to generate the list of Sheet Metal featu

that are not visible in the unfolded view.

25/39


This tasks shows how check the overlapping of different areas of the part. This is usuadone 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.

i

Click Apply.

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

Click OK.4.

When no overlapping is detected, a message isissued:

This tasks shows how check the bends of a Sheet Metal part, i.e. to detect the bends tdo not use the default bend radius parameter value, thus allowing the production teamchoose the correct tools to process the part.

Open the BendRadius01.CATPart document from the samples directory.

Double-click the Sheet Metal Parameters from the specification tree.1.

From the Sheet Metal Parametersdialog box you can see that thestandard bend radius for thecurrent document is 4mm.

Click the Radius Check icon .2.

The bends whose radius value is

different than the standard valueas defined in the Sheet MetalParameters dialog box,Parameters tab, are highlighted.

Furthermore, a list of these bends

is displayed in a dialog box.

Checking Feature Fold Visibility

This tasks shows how check the fold/unfold visibility of a Sheet Metal Part. Indeed in somcases, you can notice that a few features are no longer visible once the part is unfolded.This capability gives you the list of these elements.

Open the TangentWall1.CATPart document from the samples directory.

Click the Check Feature icon .1.

The list of the features that will notbe visible is you unfold the part,
