Patent ID: 7080462

Claim:
A detailing tool used when fabricating building frameworks or other structural assemblies comprising, in combination: a first blade having a plurality of first blade straight edges used as tracing guides for laying out markings on one or more workpieces and having a substantially planar first blade surface located between said first blade straight edges; a second blade having a plurality of second blade straight edges used as tracing guides for laying out markings on one or more workpieces and having a substantially planar second blade surface located between said second blade straight edges, said second blade being mounted on said first blade and selectively movable relative to said first blade along the first blade substantially planar surface whereby the distance between said second blade and said first blade straight edge is varied, with the substantially planar first and second guide surfaces being disposed orthogonally with respect to one another; lock structure operatively associated with said first and second blade to lock said second blade against movement relative to said first blade at selected positions on said first blade; and a support tray having a calculator support surface and a data card support surface, said support tray being pivotally mounted on said second blade and selectively movable between a generally vertical orientation and a generally horizontal orientation.
