How to draw a berm in a site

[Anonymous]

Greeting people,

If anybody say how to draw berm in cut/fill slope. for example the cut slope is 5m and 1.5:1 ratio. 

fill slope is 5m and 2:1 ratio. But i need to draw a berm between the cut/fill slope (5m slope 2m berm and 5m slope).

one important think is this is only a site not a road. 

Thanking you.

regards.

Guna.

Guna,

Welcome to the Autodesk Forums!

Looking at it in Object Viewer, things are wierd indeed. I'm not sure it's possible to do what you want to do with the berms. On the south end your existing surface is almost 30 meters above your berm feature line:

Hi sir,

I'm new to civil 3D field. Now only i learn the basics of civil 3d. The drawing which is attached previous  is wrong. I mistakenly sent it. I ask sorry about that. In this drawing i plan to draw a site in 39.17m X 33.85m. And the elevation of the site placed on 1195 point in the EG surface. So i place the pad in exact 1195 point, also cut and fill slope are mention here.

The cut slope is 1.5:1 ratio with 5m slope

The fill slope is 2:1 ratio with 5m slope.

But in this i need cut slope with berm. also i need to fill the slope with the berm. The berm size is 2m wide in 0%.

Each And every 5m slope I need horizontal berm.

I don't know how to insert berm in the cut and fill slope. So sir please help me to show how to cut/fill the slope with berm.

This is'nt perfect but can be refined to be dynamic

In a new site draw a feature line representing the top elevation of the berm then a projection grading to the cut fill slope surface. Then Paste the two surfaces together

Alternately, you can grade the berm directly from the pad with differ criteria and daylight from the berm.

I'd use the first method an walk away.

From the description and the picture in the first post I'm assuming that what you want are benches, not berms.  This sort of complex grading to an existing surface can be done using featurelines and grading but it's generally more suited to a corridor design.

I've attached a copy of your drawing with a corridor built using a subassembly that is specifically designed for benched cut and fill slopes.

Hi Spoon,

Thank you for the drawing creation. And i want to know about how to draw the benches and corridor to the drawing. Can you please explain those steps. I can use in the method from creating the bench to other drawing.

Thanking you,

Hi sboon,

The drawing you draw the slope with bench is it. Where you use assembly. how you use corridor in this drawing. in the plat form where draw the subassembly can you please give the step by step detail. its make me lot of doubt. once you give the step by step method, i will do the drawing by my self. If you Don't mind please give the step by step method. I can easily understand. please help me boss.

Thanking you,

Guna,

Here's a good Screencast from @autoMick that shows steps for grading with benches:

Hi Sboon,

Sorry for interrupt you again. What is the matter is i want to know the step to draw a bench, Which is you had already don the work. But i tries once again it make failure. I hope show, you send the tips, which you are already don the drawing. I waiting for you respond once again. Please do the needful for me. Here i attache the drawing, which your draw two days before. i need the exact drawing steps involving in this drawing.

Thanking you,

Regards,

Guna.

Hello again,

The design I created uses a corridor.  To create a corridor you need an alignment, a profile and an assembly.  It would take too long for me to explain all of the steps for creating each of those here.  The best way for you to learn those is to work through the tutorials.

I can share some tips related to this drawing:

• Notice that the alignment in my drawing has curves at the corners.  Corridors don't deal with tangent intersections very well, so you're better off with small curves.  The alignment also has a small gap between the start and end points.  This makes editing the alignment and corridor easier.
• Make sure that the assembly you build has the DaylightBench subassembly on the correct side.  My alignment runs counter-clockwise around the pad, so the sub has to be on the right side.
• The corridor will allow you to build a surface for the daylight slopes and benches, but that doesn't include the pad.  You already had a featureline and an infilll grading object for that.  I added a Combined surface, and then pasted the two pieces of the design into it.

Awwhhh... I was looking forward to the screencast 😞

Hi Steve Greeting.

Thanks for the tips for the drawing creation. I use the tips its more useful to finish 90% of the drawing. And once again i say thank to you. Hopefully i reply you again for the further doubts. Please clear all my doubts in future.

Please tell how to join to platform in a single surface.

Thanking you

thanking you,

First - your corridor will look better if you increase the frequency.

You also need a corridor surface if you want to join it with the platform.  Don't forget to add an outer boundary to it using the shrinkwrap option.  It looks like you have deleted the grading infill surface within the pad so you'll have to recreate that.

Create a new combined surface.  Paste in the corridor surface, then the pad surface.
