A–A′
Cross-section
Use ✎ Draw A–A′ on the map to drop a transect line, then mark a proposed grade here.

Drag the blue grade handles to mark a proposed grade. Below
existing ground is cut, above it is
fill. Double-click the grade line to add a
point; right-click a point to remove it.
Trench / utility-corridor takeoff
priced along this alignment · planning-grade
Neat-line geometric volumes (no pipe displacement or
trench-box / side-slope allowance), priced resourcing-first with both haul
directions — spoil off-site, bedding (and any imported backfill) in.
Uses the soil & rate set from the left panel; bedding is priced as
granular (sand & gravel).
Topo
Topo box
Use ⛶ Topo box on the map to drag a rectangle. Its shaded relief and contours appear here, with your transect lines overlaid.
Sampling topography…
Scroll or pinch to zoom, drag to pan. Drag a transect endpoint (on the map or here) to move the line — its profile re-samples on release.
Mat
Materials takeoff
Use □ Footprint on the map to draw a footprint polygon, then estimate topsoil strip and stockpile / borrow volumes from the DEM — priced as material line items.
Estimating materials…
Topsoil strip = strip depth × the footprint’s planimetric
(map) area, so it ignores terrain roughness. Stockpile is the volume
above the chosen base (a pile); borrow is the volume
below it (an excavation / void). Planning-grade, not pay-quantity.
Pond
Pond / basin excavation
Use □ Footprint on the map to draw the pond outline, then size a flat-bottom, uniform-depth or dish basin with sloped banks. Add an optional △ Spoil berm to check the cut/fill balance.
Estimating pond…
The freehand sketch style is a 1-D corridor approximation, not a basin surface. Use ✎ Draw A–A′ to drop a transect across the pond and shape the floor on the cross-section — it’s honestly labeled as a corridor estimate, not a 3-D pond.
Spoil berm & balance
optional · shrink/swell aware
Depths and volumes follow the unit selector at the top of the panel. The pond only ever cuts; a berm only ever fills. Planning / habitat-restoration screening grade — not a pay-quantity survey.
Exhibit
Master figure
topo + every section + proposed grade from bench lines · planning-gradeDraw at least one transect (✎ Draw A–A′) to build the composite exhibit. Import your color-coded bench-line KMZ (leading edge / −4′ / −8′ / −12′) so sections that cross a red leading-edge line get a proposed grade.
Roles are auto-detected from each line's name first ("Lead Edge", "-4' Line"…), then its color. Lines named like water features (river, bank, channel, shore…) are never auto-assigned a bench role — blue river-boundary lines would otherwise be mistaken for −12 ft lines and deepen the cut. Check the dropdowns and override anything mis-detected. Sections with no red crossing plot existing ground only.
