LinkSlopeToSurface Assembly Superelevation not Working Properly

Link slope to surface subassembly wil not reflect info from the Superelevation info properly.  You have to toggle cut and fill to get to show proper rotation.  Leaving set to "cut and fill" should work for all because the slope should be coming from SE info (when left set to 'cut and fill" it shows the opposite of what it should show, ex if slope is supposed to be -6% from SE info it draws at 6%).  I tested the linkwidthandslope subassembly and it reads the SE info fine and rotating as to be expected, although i need an assembly to target a surface and also rotate properly.

What version of Civil 3D are you using?

 

Would you be willing to upload your drawing so I could take a look at it?

If it is too big to post here, please let me know and we can make other arrangements to get me the data.

I am using Acad c3d 2013, drawing is way to large to post.

M,

 

From the Help Section:

 

Superelevation
"If you are adding superelevation to any alignments, do so before creating the corridor. Also, the superelevation data is not dynamic, so it does not update if you grip-edit the alignment. Therefore, add the superelevation after the alignment design is stable, or be prepared to redo the superelevation if the alignment is modified."

 

Are any of these a possibility?

That is why i substituted the LWS (Linkwidthandslope) for the LSS to make sure it was pulling the data properly from SE table and it worked as expected. I just modified the SE info to the opposite of what it is supposed to be to check if this works and it does not fix appears to be leaving everything positive. I left the LWS with the assembly and it rotated to match SE data which leads me to believe it is something wrong with LSS subassembly. I was toying around with Subassembly composer to see if i could make my own LSS with SE capability but have not had any luck. Thanks

When add link in is set to Cut and Fill it will only give result in Positive slope for whatever SE info gives, only way to get a negative slope is to set add link in to fill only which would sorte of be pointless. Would be better off generating a design surface from the linkwidthandslope and generate a polyline between my finished gound and design surface and use it as a target for the LWS. More steps than i'd like to have.
