Top soil Stripping

[Anonymous]

How can I create a top soil stripping line in an assembly

[japa40]

dont ask about top soil calculation!

autodesk just won't hear about it.

I did a search, and found lot of posts with no "autodesk replay" about this easy task.

i dont know what to do with a cross section that has no top soil drawn and calculated!

hey autodesk, should i calculate and draw the over 600 sections manually?

I guess the stripping assemblies dont work?

thx for replay
but , I could not do the job using assemblies:(
the documentation is not good enough and the assembly looks not to do the job correct. maybe its for another situation.
for each section, the fill amount must increase, cut must decrease and a separate top soil area must be calculated.
a line for top soil under EG must be drawn too.
ill work more on assemblies, but after I get don't the 600 sections manually 😞

Seems to me if you had a topsoild surface this would be rather simple to get the volume with hand drawing or hand calculating. If it uniform depth tehn that must mean you can paste eg into a topsoil surface lower it then calc the material and add to the cross section data. If its not uniform then you must have knowledge of the data to create a TS surface and do the same

hi Joe
thx again for replay. sorry for my poor English. but ill try to explain it
anyway.
I thint , that there is no special type of surface, called TS surface. I
guess you mean a new surface with "data point" of Eg or totally a new "data
point" series.
but the job wont be done this way. C3D must be able to do the calculation
and draw the graphic in section view. (and I mean its really easy, but too
much for a manual work)
as I said I can use tricks and will use it too. a combination of Excel and
C3D can draw the section view twice. one is the full section view and the
other is a hidden section view with only a topsoil polyline to see. they
will be positioned in same xy-position.
and the calculation will done in excel an imported again in C3D. the
section view's table will be useless then! (good job autodesk)
as you see these all are really tricks. I could do also the stationing this
way.
thx

I generally create a dynamic base of topsoil surface (using the trial pit/borehole depth/thickness data and volume surfaces) and calculate the corridor quantities to this base of topsoil surface.

The total topsoil volume can be derived from these models too

Hi all

If you have a corridor design the stripping subs are the ideal tool for the job but this can also be done fairly easily with manual operations. Model needs to be rebuilt if the FG boundary changes

New file and import EG and FG.

Extract boundary for FG and convert to 2d pline if settings required

Offset boudary .1 units inside

Make new surface named 'EG Step 1 Lower' (or whatever you need)

Paste in EG and lower stripping depth, apply inner pline as outer boundary

Convert outer pline to fline and assign elev's from EG, add to a new surface named 'EG Step 2 Datum' (or what ever again 🙂

Paste Step 1 surface into Step 2 surface.
