Trouble Consistantly Daylighting from SubAssembly to Alignment Target

232 Views, 16 Replies

This is my first corridor and I've been slowly working my way through it, but just seem to be running into problems left and right. My latest problem is the following;

 

I have my Corridor's Subassembly Daylighting set to target my Left side 33' R/W offset alignment. For 90% of my alignment everything is working fine or at least appears to, but I have 3 different areas where the Corridor refuses to daylight from the bottom of the 1' ditch out to said left alignment target even though the ditch is well below existing grade. I've attached 2 screen grabs.

 

Any help will be much appreciated.

 

Thanks.

Are there any maximum or minimum grades on the daylight assembly that might keep it from tying out to that point?

Mike,

 

I've attached screen grabs for Subassembly and its Properties.

Just for grins, what happens when you change the cut slope from 4:1 to 3:1?

Mike,

 

When I change the slope to 3:1 per your suggestion it daylights properly. Problem is that 3:1 slope doesn't reach out to the 33' R/W further down the corridor. Does that mean I'll have to create a separate SA and split my region (never done that before) and use the 2 different SAs?

 

Attached images. 12+50 wasn't working with 4:1, but is for 3:1. 16+00 was working for 4:1, but now isn't for 3:1.

in your corridor properties, is that subassembly endpoint linked to your offset?

Mike, If you mean is my Target set, then yes, I have the 33' left side alignment set as my Target. Unless I'm not fully understanding what you are referring to.

 

See attachment for Corridor Target for SA.

Bryan,

Based on how you've got your corridor set up, try the DaylightInsideROW assembly instead (see attached).

Mike,

 

Will this target the 33' R./W? The client needs the entire R/W used up. They would like a 4:1 slope on the backslope of the ditch, but if at 4:1 it goes beyond the R/W then it needs to target whatever the existing elevation is at the R/W no matter the slope and if at 4:1 it falls short of the R/W then it still needs to Target the R/W so that all 33' is used up by the Ditch.  That is why I felt if I just Targeted the R/W Alignment then it should have Daylighted directly to the existing surface elevation at 33' no matter what. I thought a Target was  supposed to Override other set Parameters. Will the DaylightInsideROW SA do everything I need? Really didn't think this part of the Corridor design would be so difficult. To me seemed pretty cut & dry.

That subassembly should do what you need it to do.  

I've found the first couple of corridors are learning experiences.  After you get a couple of them under your belt, you start developing a couple of "pet" subassemblies that you learn to opperate really well.  After that you start adding more into your skill set.
