To Edit a Material
If you are editing a model that contains a material created in Creo Simulate before Pro/ENGINEER Wildfire 3.0 and if this material is a non-isotropic material or a material with functions, parameters, fatigue properties, or failure criteria, then you must convert material data in the model to the latest format in Creo Simulate before you begin editing.
1. Right-click a material on the Model Tree, on the shortcut menu, click Edit Definition. The Material Definition dialog box appears. After editing the material, click OK.
2. Alternatively, you can use the following steps to edit a material:
a. Click File > Prepare > Model Properties. The Model Properties dialog box opens.
b. Click change in the Material line. The Materials dialog box opens.
c. In the Materials in Library or Materials in Model list, select the material that you want to edit.
d. Click or click Edit > Properties. The Material Definition dialog box opens.
e. Modify the name, description, and other properties of the material.
f. If you have selected a material in the Materials in Library list, then Save to Library becomes available. To save the material to the library, perform the following steps.
a. Click Save to Library. The Save a Copy dialog box opens.
b. Browse to the material library directory and click OK. If you have added or edited appearances, then the Save dialog box opens.
c. Click OK. By default, the appearances are saved in a file named global.dmt in the same location where the material file is saved or in the location defined by the global_appearance_file configuration option. You are taken back to the Materials dialog box.
3. If you have selected a material in the Materials in Model list, click OK in the Material Definition dialog box. The Materials > Definition dialog box closes and you are taken back to the Materials dialog box.
