K Factor Grayed Out

Hello Everyone. Here's a question about the K Factor in a component.

When I open a part, I go to the EDIT menu and select SETUP, from there I'm able to select the bend allowance and select my K/Y factor

but they show grayed out...

If I select PARAMETERS instead

%24121884945F19822.jpg

I can see what the current value is. I get a message that the value has been edited from the default.

I can reset the whole table by right clicking

But still, I'm not able to change the values.

Now, if I select a flange and EDIT DEFINITION, I can control the bend allowance independently...

Am I doing something wrong? Do you think these options are grayed out because the part was modeled in certain way or because my config is set up to gray it?

If I change it in every feature, would it have the same effect?

Thanks in advance.

I'm using the Windows 7 64 bit, creo elements pro 1.0 (WF5) M170.

Re: K Factor Grayed Out

Hello Alan and welcome to the forum.

I am just guessing here but if the Y-factor has a value, the K-Factor may not be available.

Maybe you can chase it with the following information.

This is the relations built into Creo 2.0 sheetmetal, empty part -

/* The following relations make the bend allowance parameters */

/* of part to be dependent on the assigned material, if the value */

/* of the parameter SMT_UPDATE_BEND_ALLOW_INFO is YES. */

/* If you remove or change these relations, the check box */

/* 'Use assigned material to define the value of the bend */

/* allowance parameters' in the Bend Allowance category */

/* in sheet metal Preferences dialog box might stop working. */

if ( SMT_UPDATE_BEND_ALLOW_INFO == YES && exists("PTC_MATERIAL_NAME") )

if ( string_length( material_param("BEND_TABLE") ) > 0 )

SMT_PART_BEND_TABLE_NAME = material_param("BEND_TABLE")

endif

if ( material_param("INITIAL_BEND_Y_FACTOR") > 0.0 )

SMT_PART_BEND_ALLOW_FACTOR_TYPE = "Y FACTOR"

SMT_PART_BEND_ALLOWANCE_FACTOR = material_param("INITIAL_BEND_Y_FACTOR")

endif

endif

SMT_DFLT_BEND_RADIUS = SMT_THICKNESS

SMT_DFLT_CRNR_REL_WIDTH = SMT_THICKNESS

SMT_DFLT_CRNR_REL_DEPTH = SMT_THICKNESS

SMT_DFLT_BEND_REL_WIDTH = SMT_THICKNESS

SMT_DFLT_BEND_REL_DEPTH = SMT_THICKNESS * 2.0

SMT_GAP = SMT_THICKNESS * 0.5

SMT_DFLT_EDGE_TREA_WIDTH = -SMT_GAP

SMT_DFLT_MITER_CUT_WIDTH = SMT_GAP

SMT_DFLT_MITER_CUT_OFFSET = SMT_THICKNESS * 1.1
