Hi all . I am new to all that is excell and have been doing very basic things up till now . I would like to create a calculator for determining bend allowances for sheet metal for folding . I would like to have maybe drop down lists of materials ie aluminium , mild steel and stainless steel . Then perhaps a drop down list of thicknesses and also the tooling . so I was wondering if there was any way that if for example the material is aluminium - 1mm thick- 12/90 vee then the bend allowance would be ? I have looked on the internet including countless youtube videos but cant seem to find what I want to achieve . was wondering for any input - ideas . or if im simply wanting it to do something that it is not designed for . you feedback would be gratefully received many thanks.
