Guess i will have to change it myself to metric. I checked this out with our Vendor who told me it is an oversite. A spreadsheet will appear but all the values will be in imperial. Now if you go to Insert, Bend Tables, New a pop up will appear asking you for units and type. Therefore 100mm minus 92 is 8mm bend Deduction. If I bend this to 90 degrees and measure the outside to outside dimensions they could be both 50mm. For Example I could have a piece of 4mm material, 92mm long. Bend Deduction is the difference between the flat unbent pieces length and the sum of the outside to outside dimension of the bent piece. Toolbars for add-in products are available if you have installed the products and added them in to the SOLIDWORKS software. On the Toolbars tab, select the toolbars to display. This means that this part uses a fckin old template that causes numerous of issues (namely: greyed out newer features, issues with the bounding box, issues with multiple flat patterns, issues with multi body parts, faces losing references. To display SOLIDWORKS toolbars: Right-click in the window border, click Toolbars, and select or clear a toolbar name. If you are using equations or design sheets that allow material to change it is absolutley critical that your model is built in a way that allows the material thickness to be increased in the correct direction. If you look at the feature tree you probably do not have a sheet metal folder but only a feature. Yjeepster - You are right about the material thickness.
