Area Grading

[Anonymous]

Hi everyone,I have created surface from topo and placed tables(12 piles in each table and there 1000 tables,it is solar plant) on that surface after taking spot level of each piles I want to highlight that pile or area which has low and high level automatically and calculate that quantity( 1.Allowable elevation difference within pile -250mm or +250mm, 2.Allowable level difference between consecutive tables are +100 or -100.)I have problem in grading can anyone suggest how to resolve this issue.

Table size-33mx4.25m and table gap 100mm.

Please find the attachment for your reference.

This probably doesn't mean much but I believe that I remember this same question asked in the past.

(months?, years?)

What kinds of problems?

As far as highlighting the cut and fill areas. Once you've created a volume Surface. Apply a Surface Style that has 2 bands. One above 0 and one below 0.

[tcorey]

Get the high and low areas using an Elevation Analysis and by applying a Surface Style that turns on the Elevation components (Display tab of Surface Style Editor).

Calculate volumes between elevations by using _AeccStageStorage command. In the Surface Style, set your contour increment to match the report you want. If you need volumes between every half meter of elevation, set your contour increment to 0.5, then run the stage storage command.

Hi @Anonymous , welcome to Autodesk Community!

Did the response from @tcorey help answer your question? Let us know if you still need help.

yes ,but i did not get any response which is useful in this case.

Prashant,
I zoomed your attached PNG 1000%, but understand eludes me and I have to admit that I completely do not understand what you are trying to do. Please elaborate on what you mean by "piles" and "tables". Do you mean piles of dirt and AutoCAD tables? Attaching your drawing would help immensely.

Here rectangle part is table and  there are 12 dots which is pile you can see attachment.

I want maintain level difference within first pile to last pile is -250mm or +250mm and last pile of a table and first pile of next succeeding table should be -100mm or +100mm.

Civil3d give us the tools to analyze grade differences. It also give the tools to prepare grade differences. However, out of the box it for not give tools to globally automate the prepared differences.

if I understand your task correctly,  you need to determine if the grade differences across a table is greater than x.

the natural slope?

a proposed slope?

difrrence between both?

which direction?

lets assume the differences you are looking for are between the top of piles and ground level.

1. Make a surface of top of piles 

2. Make a surface of ground level

3. Make a volume surface of ground vs top pile

4. Set surface style to display the differences you require.

similar analysis for any other permutations

This sounds like something that Dynamo could be used for but I have no idea how....😉

Dave:

I feel like he is referring to structural piling.  Vertical structure members driven into the ground for support.

Prashant,
"...rectangle part is table and there are 12 dots which is pile you can see attachment."
Sorry to be so dense, but which attachment?
Does "table" = building pad?
Does "pile" = structural pile or solar panel mounting pole? (As @Anonymous says)

Dynamo! 😩 how many apps are we supposed to learn? 😂

Some puzzle 🤔

It is not possible to create more than 1k surface since there are more than 1000s table, yes we can create ground surface but we can not compare since we can not create surface for each required level.As I have mentioned we can allow some elevation difference to reduce the quantity either + 100, or -100 since have to maintain some slope like may horizontal or 5 degree etc and level difference between one table to another not more than 100mm so each table is related to another.

I don't think you need to represent each individual table on a surface to design this.

Create a grid of feature lines. It doesn't have to be at edge of every table. It can be every 3 rows/columns of tables or something. Something like 20 lines total which is completely manageable. You can make a surface out of these feature lines and haves styles made to visualize slopes. You can then make a volume surface and show that in an elevation style to visualize elevation change. If you need to fine tune grade changes at certain areas you can add elevation points as you need them and make adjustments on the feature line elevation editor.

Once you have a rough design that you know will work you can fill in the details (add more feature lines)

Finally, just add a grid of spot elevation on your design surface to get your finished table elevations.
