To Define Sheetmetal, Surface, and Detailing Properties
1. Click the Miscellaneous tab in the Material Definition dialog box when creating a material. The Miscellaneous tabbed page opens displaying a default value of 0.5 for Initial Bend Y-Factor.
 
* Creo Parametric checks for errors in the material properties that you specify whenever you save a material, add a material from the library to the model, and at run time in both Creo Simulate and FEM modes.
2. Under Sheetmetal Properties, type a new value for Initial Bend Y-Factor and Bend Table, if required. The valid value for Initial Bend Y-Factor is a positive real number (includes 0.0) and for bend table is a string with a maximum length of 31 characters.
3. Under Surface Properties, type values for Hardness, Hardness Type, and Condition, if required. The valid value for hardness is a positive real number (includes 0.0) and for hardness type and condition, a string with a maximum length of 31 characters.
 
* You can choose not to specify values under Surface Properties blank. If you specify a value for one of the surface properties, then you must specify values for all the surface properties.
4. In the Cross Hatching box type the name of a file that has a .xch extension. This file type contains the cross hatching pattern that you want to apply to cross sections. Type the name without the .xch extension and limit it to 31 characters.
 
• Creo Parametric searches for the specified file with .xch extension in the path defined by the pro_crosshatch_dir configuration option, the working directory, paths specified by the search_path configuration options, and the default crosshatch directory, that is, <loadpoint>/text/crosshatch. If the specified file cannot be located, then the default cross hatch pattern is used.
• When creating a new material or during automatic conversion of a material that existed before Pro/ENGINEER Wildfire 3.0, by default, the Cross Hatching box displays a value that corresponds with the name of the material.
• Cross sections that were created before a material is assigned to a model are not updated after you assign a material with a different cross hatching pattern to the model or when you change the material assigned to a model.
