I am trying to offset a toe of slope line to a certain elevation at top of berm in a fill situation. I feel like there is a way to do it but I am not finding the right command or workflow.

In my situation i have a top of berm elevation and a staked silt fence line at toe of slope. This is a field fit due to a creek avoidance on two sides of the location. I received points from the field where toe of slope needs to be and so I created a line there at planned toe of slope and I need to fill up to the berm elevation at a 2:1. It is a very irregular shaped location and toe of slope is a varying elevation all around the pad so i can't just offset to an elevation.

I tried create surface tie but I can't get it to tie up in a fill. I have tried to use my toe of slope line as a boundary and create a planer surface at a constant elevation at top of berm height to tie  but I am not getting the results needed. I have my honor sign of tie turned to yes.

I hope I explained this well enough for someone to help.

Thanks

Can you provide your project vce?

I have attached the vce to my post.

Any help is appreciated.

Thank you!

Just so I'm following correctly. You need a new 2:1 slope from the toe to an elevation of 1989.5? You can use the sideslope command to to a slope/elevation command. The purple line below is using the sideslope to elevation of 1989.5 @ 2:1.

I tried create surface tie but I can't get it to tie up in a fill.

This is correct. you're trying to tie to a surface that's sitting above your line. It needs to be a cut.

Yes you are following me correctly. That is the result i am looking for. I just couldn't for the life of me get the right command I knew existed. Sideslope to slope/elevation is what is what i was looking for. So theoretically if i ran a cut slope on the surface tie instead of a fill i would achieve what i am wanting too it just would be categorized as a cut but net the same result? Sideslope is definitely a quicker solution though.

Again thanks for your help! I knew it worked but I just couldn't remember how.

If you are running TBC 5.1, I would use the create side slope tool. This will do exactly what you need. 

See the video for a walk through.

The plane surface and the surface tie can work but it is definitely trickier to get working correctly and it requires a lot of exploding. 

Thanks Patrick.

I'm going to try the sideslope like you and Erik have said here. I am going to check out your video too.

Again thank you very much!

Just watched the video. Thank you very much.

This worked for what i was looking for. Great explanation.

No problem!

So theoretically if i ran a cut slope on the surface tie instead of a fill i would achieve what i am wanting too it just would be categorized as a cut but net the same result? 

Yup. It will give you the same results as if doing a slope/elevation.

You'll still need to edit line at the top of the berm because you will have some overlapping because the way your toe is.

I guess you could also do a surface tie to your "offset surface" as well.

Awesome!

Thank you for all your help!! This forum is a great resource!

Thanks Guys!!

Here is a quick screenshot of what i am trying to accomplish. As you can see there is fill all around this knob and basically the engineered plan put every slope in the creeks on both sides. Had my field guys go out with rover and shoot where the best place to put the toe of slope in the real world and then had to get back up to the berm height and back to finish grade for the drilling rig to sit on all while maintaining as much surface area as possible. Also needed straight edges on the pad so i couldn't exactly follow my to offset. We were able to fudge the 2:1 to a 1.75:1 in a few places to gain room. A.C.O.E. is present on this job so anything in the waterway is a big no-no. Now just have to find a place to waste 35,000 yds of material from the design change.

Again thank you for the help!
