Most of times, models created in inventor, needs to be material quoted, so you need maximum part dimensions (similarly to sheet metal length and width), it would be great inventor to create a bounding box or cylinder to define an minimum stock material needed. (a work bounding box not included as a model Feature).
By getting this, resulting dimensions for cylinder Stock (Diameter and Length) and Box Stock (x,y and z) can be shown in Parameters Table.
By the moment im getting this done by manualy, and means a great time saving for Drafting and quoting departments, because there is no need of creating a Quoting Drawing Just enough processing stock parameter with ilogic and placing it down in BOM for Excel Export.
