Each new sheet metal part is created from a template. When you use the default sheet metal template installed with Autodesk Inventor, the default material, sheet metal rule and unfold rules are applied to the sheet metal parts created. You can use this template or another predefined sheet metal template (English or Metric for example), modify one of the predefined templates, or create your own templates by copying and modifying one of the existing templates. If you use a part template and then convert the model to sheet metal, the material defined in the part overrides the material defined in the Sheet Metal Rule of the sheet metal template.
You can define a style in a sheet metal file and save it as a template, and then use it as the basis for new sheet metal parts. Include the following information:
Specify iProperties such as cost center, project name, or manager and save them as part of the template. Use iProperties to find, track, and manage files, and automatically add and maintain information in title blocks, parts lists, and bills of material.
Any sheet metal file can be used as a template when you save it in the Autodesk\Inventor [version]\Templates folder. Set any template to be the default template for creating new sheet metal parts. To make a template the default, save it in the the Templates folder with the file name sheet metal.ipt. To avoid overwriting the existing default template, move or rename it before saving the new template.
Files that reside in the Templates folder appear on the Default tab of the New dialog box when you create new files. Files that reside in a subfolder of the Templates folder appear on other tabs in the New dialog box.
