Use the sample bend table, and specify units of measure and tolerances.
- Browse to the sample bend table spreadsheets in the \Autodesk\Inventor [version]\Design Data\Bend Tables folder (in \Documents and Settings\All Users\Application Data) and double-click one of the .xls files to open.
- Scroll to the line that starts with /U, and enter units of measure. The default is cm.
- Scroll to the lines that starts with /T and enter the following:
- /T1 +/- tolerance for sheet thickness.
- /T2 Equal minimum and maximum bending radius.
- /T3 Tolerance for equal minimum and maximum opening angle.
Note: Tolerances 2 and 3 are used only under special conditions, as noted in the table.
- Select FileSave As, give the spreadsheet a new name, and click OK.
