calculte cut and fill in civil3d

[Anonymous]

I find it difficult when you have alot of roads to calculte cut and fill volume in civil 2017 it make me do volume surface firstly then calculate cut and fill this take alot of time when you have many roads but in civil 2012 it is easy to calculate it is not need to create volume surface 

if there is command to use civil 2012 calcualte cut and fill stayle in civil 2017 .

You need a base surface (existing) and a comparison surface (proposed) in either version. When you say you have many roads are you creating separate corridors and corridor surfaces for each road? If so you can create a new surface and paste all of the road surfaces into the one surface and use that for comparison in the volume surface. 

[M_c3d]

Cut & fill volumes are generated by comparing two surfaces in civil 3d, normally an existing surface and a proposed surface.

To calculate the volume between two surfaces;

You need to create a surface from your existing topographical survey information and this will become your base surface.

You then need to build your corridor with the vertical profile and assembly you require. A surface can then be generated from the corridor, this can be pasted into a combined surface that can contain multiple roads and will be your your comparison surface. You can add featurelines to your proposed surface to add more features, buildings etc.

You then do a cut and fill analysis between the two surfaces with the base surface being the existing surface and the comparison surface being the proposed surface. This will give you a volume required, either cut or fill needed to get to the proposed surface level

==============================================================

If you want to include a top soil strip and depth of construction to get the volume from the top soil strip level to the formation level of the road;

Typically you would take a top soil strip off the existing surface, say 0.2m (site investigation would give this information). You would create a new surface (top soil strip), pasting in your existing surface and lowering it by -0.2m. This will again be your base surface.

You would then take your proposed surface and create a new surface surface (proposed formation level), say the depth of construction is 0.45m. You would paste the proposed surface into this surface and lower it by -0.45m. This surface would be your comparison surface.

You then do a cut and fill analysis between the two surfaces with the base surface being the top soil strip and the comparison surface being the formation level surface. The volume provided would be the difference between the top soil strip level to the formation level of the road. This is handy to give the volume that is between the top soil strip and the formation level, either cut or fill. The road construction would be an off site import so wouldn't need to be included in the volumes.

i need to claculate volume for roads separately not combine in one surface

[M_c3d]

for each individual road or for all roads?

each individual road;

• Generate a surface from each road and this will be your comparison surface

all roads;

• Generate a surface for all roads and combine them together so that the surface is only made up of roads and this will be your comparison surface

Dear Friend,

Can you explain this bit more. As I see both images show same thing. If you click top left button of 2012 image you will get same window as in 2017.So at 2012 also you will make a volume surface.  The method is almost same.

Thanks

I would approach it in a sequenced modular construction.

Build an overall existing surface.

Paste any design corridors and/or grading to make an overall proposed surface.

Build an overall volume surface from the two.

Copy this surface for each volume area and add a boundary to limit it to just that area.

[neilyj666]

It generally depends on the complexity of the project but I would typically extract the proposed boundary(ies) for the corridors and combine to get an overall boundary and convert to 2D polyline at 0. I would then add polylines at the location where I wanted to get the volume calculated. MAPCLEAN to break apart and remove tail ends and create parcels.

Then use the the Parcel Volume Report to get the volumes from the volume surface

To bring back the old report volumes table like in Civil 2012, just type the command REPORTSURFACEVOLUME

thanks you solution is too right

You can also modify the ribbon to add this command back where it belongs...!!!!
