Shoulder Subassembly cut vs. fill

[BrianHailey]

Here's my situation, when I'm in a cut situation, I would like the end of my shoulder to be vertical but, when I'm in a fill situation, I would like my shoulder to extend all the way out to the daylight line (if possible). Is there a method to do this?

See the attached image. The top subassembly is the ShoulderExtendAll sub and it looks like what I want in a fill situation but, I don't think it would work in a cut situation. The lower subassembly is the basic shoulder, which looks like what I want in a cut situation.

Thanks for any insight,

Brian

Brian,

I can't think of anyway to do this without either using a different
subassembly in cut/fill, or making a custom shoulder subassembly.

Brian,

Just a thought that I haven't begun to test: You could make the shoulder using the ShoulderVertical subass, then attach to the end of that both: (1) a ShoulderExtend subass of 0.001 width that then has a daylight slope as needed for fill situations, AND; (2) a Daylight subass that is specified to fill flat (almost horizontal) and cut (almost) vertically. Thus, you should get one error message per station when building your corridor, but there shouldn't be any stations that use both subassemblies and thus you'll only get one daylight point for each station.

As an alternative to (2), you could use a generic LinkToSurface subassembly.

Don't know if any of that will work, but I thought I'd throw it out there.

HTH,

Thanks Trevor. I'll look into that.
