Bolts2DM: Metric Bolts/Nuts/Washers for Steel Detailing
Bolts2D Metric parametrically creates bolts/nuts/washers in plan or elevation views for easy placement in steel details. The additional module included in this app is Slotted Holes. Dimensional data for the bolts is stored in external ASCII data files which you may add additional dimensional information on bolts or nuts that are unique to your specific application. Default sizes are included in imperial and metric dimensional data files.
