I got a creek bed and bank that need rip rap. I have the finish grade designed but I need to create a SG for the surface and it needs to be a thickness not a vertical offset. I tried using MSI manager and I edited the site improvement to create a thickness but it is still creating a vertical offset surface when I use the create subgrade command. Any idea on what I am doing wrong!?
In the MSI Manager, do you have the Subgrade Adjustment Basis for your rip rap set to “By perpendicular offset”, not “By vertical offset”?
Yes, I did set the offset to thickness. Thats what is bugging me.
Changing that setting typically works for me. I just created a 3:1 slope to test this out, and put a line down the middle to allow 2 separate site improvements to be side by side. The left side had the perpendicular setting, and the right had the vertical setting in the MSI manager. My cut-fill map is different with the 2 separate areas and seems to be correctly adjusted to the thickness on the perpendicular site improvement.
You know what, I think I was expecting a different result… I was hoping it would created the SG surface offset perpendicular to the linestrings creating the top surface. I see know what it is doing. I guess I will have to comp what the bottom stringlines to create what I want.
Thank you,
Can you just the - Cloud Services - Create Perpendicular Surface Offset?
Edit:
That is what I was looking for! I will give it a try!
