What's the best way to calculate volume from a site plan drawing?

[Raspberry Toupee]

Hi there,

 

I'm new here, it's great that there is resources like this on the internet. Thank you for this site.

 

I'm trying to work out a way to calculate the fill volume difference for a proposed landscaping plan (images attached) and was hoping someone could help me find a simple way to model and calculate the amount of fill required to do the job.

 

Hopefully this is enough info, please let me know if I need to clarify anything.

Any ideas would be greatly appreciated.

Cheers.

First of all welcome to the CADTutor forum.

 

What you are wanting to do here is a task for AutoCAD Civil 3D, plain old vanilla AutoCAD cannot do it. If you do not have access to AutoCAD Civil 3D you could use the CadTools surface commands to do it. CadTools is a free program that works inside AutoCAD and can be downloaded rom here: http://www.glamsen.se The author of the software is Lars Karlsson and it has may useful tools that are not available in AutoCAD.

 

You have some very intersting looking contours in your proposed landscaping plan and should ensure check the integrity of all countours before continuing. Contours cannot start or finish in the middle of nowhere.

 

Good luck.

Thank you for your input, I was hoping to avoid Civil 3d, it looks like a massive learning curb from what I have seen. I'll check out the glamsen plugin, hopefully there are some easy to use tools there.

Yeah, some of those contours look a bit suspect. I am guessing they have been hand drawn?

 

If Coffey Engineering designed the 4m battered slope at the font and whatever it is at the back, then I would just ask them for the earthworks details. It won't take into account all your minor landscape changes although would account for the bulk of the earthworks.
