... of representation is sufficient. Hi Dave, It's sufficient, but having gone to the trouble to create partial templates for the slip crossings, you may as well do the rest of it, like this os_check_rail.png I split the check rail out as a separate partial template, then changed the "size 2 MS check rail working length" to 324 inches full-size (and reduced the blanking to see it). Sizes 1 and 3 check rails are not relevant at this crossing angle, and the other dimensions are unchanged: os_check_rail_length.png That's at real> customize V-crossing> wing and check rails... menu item. Notice that the lower check rail needs extending to match, to ensure that the crossing is properly checked through the knuckle. regards, Martin. posted: 19 Nov 2008 03:25 from: David Martin Wynne wrote: David wrote: I assume the two wing rails get constructed as one continuous rail, but that this kind of representation is sufficient.
