Bend Radius

Specifies the inner bend radius applied to flange features.

 

K-Factor

The K-Factor (see Notes section below) is a ratio based on the expansion (stretch) and compression properties for a given material.  It indicates the location of the neutral axis within the thickness of the sheet metal.  For example, a K-Factor value of 0.50 places the neutral axis at the center of the thickness of the sheet metal.  The default value is 0.41.  The table below includes K-Factor values of various materials and hardness.

 

Thickness

Specifies the material thickness for sheet metal parts.

 

Flat Tolerance

Refers to the flat tolerance allowed for sheet metal parts in their unfolded state.  The default value is 0.10.

 

 

 

Refers to the width of the reliefs that are created automatically during the Partial Sheet Metal Flange command.  Select the relief width method Ratio or Value and then enter the value in the input field provided.

 

• Ratio - The value refers to a ratio of the sheet metal thickness (i.e., a value of 1.50 = 1.5 times the material thickness).

• Value - The value refers to the absolute width of the relief regardless of the sheet metal thickness.

 

 

 

Folded, Unfolded

The state works both as a control and as an indicator.  You can select Folded or Unfolded to change the state of the part (i.e., the part will fold or unfold accordingly).  You can also use the Fold and Unfold Sheet Metal Part commands to perform the same function.  When this form is displayed, the state flag indicates the current state of the part.

 

 

 

• The Fold and Unfold Sheet Metal Part commands will only update the state flag if during those command you select all bend faces (middle-click) to be folded or unfolded.  Partial folding or unfolding of the part (i.e., not all bend faces were selected) will not update the state flag.
   

• All bend faces must be marked using the Mark Sheet Metal Bend command in order for the state flag to control the state of the sheet metal part.
