... the normal. And they are not just simply rotated. The jaw casting forms a parallelogram with one axis aligned with the base and the other axis aligned with the rail. Here's one way to produce angled jaws. Starting with the base plate, the solid line represents the gauge face of the rail. 2983_041946_070000000.gif This is it in wire-frame plan view. Green lines are construction lines. 2983_041946_070000001.gif Now we drag the seat on to the base and snap it to the intersection of the center-line and the rail. 2983_041946_070000002.gif The seat is actually a block that can be used repeatedly in any model. If a block is edited any changes will be immediately replicated in all instances of the block. (And blocks can be nested. For example, a chair screw can be a block and if I edit it all the screws in a turnout model will immediately reflect the changes.) 2983_041946_070000003.gif We've now rotated the seat (4 degrees this time.) Obviously it's much too long. That's where those extra construction lines that are inset from the ...
