Leap Steel 16.02.00.02 appears to be crashing on a regular basis in the Member Definition Stage. An icon appears in the bottom left of the graphic window. See attachment. Is this a known issue? How can I fix it? thanks.

When modelling a curved bridge : -how do I know which one is G1 ? - if I set up G1 and copy to the other girders will it copy concentrically? (i.e. will the crossframes be radial?) thanks.

Certain DOTs do not require impact to be included in the design of elements below the bearings. in this case, is it still necessary to break down the manual LL input into lane and truck if the impact is set to 0% ?
