AutoCAD Plant 3D 2018 - Metric Bolts in a Mixed-Metric Plant 3D Project

By Andy Davis

The standard bolt lengths used for ANSI fittings in AutoCAD Plant 3D are defined using an Imperial Bolt Mapping Standard. When using the default isometric styles in mixed-metric projects the bolt sizes and lengths contained within the ASME catalogues and specs produce a BOM showing imperial bolt diameters with metric lengths, often rounded to inappropriate values.
