From a blank site to a costed one

Short, in-order lessons on drawing a site plan, grading the terrain, reading contours and pricing the earthworks. Each one is a thing the editor actually does — no theory detours.

Track 02

draw the plan

  1. 01

    Draw with the shape tools

    start here

    Rectangle, ellipse, circle and triangle: how each is drawn, what Shift does, and how to get exact sizes.

    5 min
  2. 02

    Snap to a grid

    start here

    Set a grid step so points land on round numbers, and learn when to switch snapping off.

    4 min
  3. 03

    Draw a polygon point by point

    start here

    Click out any outline one corner at a time, close it, then move, add and remove points with the same tool.

    6 min
  4. 04

    Sketch freehand, then simplify

    start here

    Trace a boundary with the pencil, choose fill or strip, then tidy the stroke into a clean outline with a metre tolerance.

    6 min
  5. 05

    Draw lines and paths

    start here

    Use the polyline for paths, walls and edges — open lines drawn point by point on the paths band.

    5 min
  6. 06

    Trace over a site plan or photo

    start here

    Drop a survey, plan or satellite image behind the plan, set its scale from one known distance, lock it and draw over it.

    7 min
Track 05

shape the terrain

  1. 01

    Raise your first plateau

    start here

    Give drawn areas their levels and watch the ground grade up to meet them. Explains ground zero and how levels fuse.

    6 min
  2. 02

    Dig a pond or a pit

    start here

    Draw an area with a negative altitude, give it a water texture, and read the volume it holds.

    5 min
  3. 03

    Slope a surface

    start here

    Tilt an area by angle and direction, or click two points with known altitudes and let the editor work the slope out.

    7 min
  4. 04

    Smooth banks and terrain detail

    start here

    Rounding, mesh detail and the filler ground: the settings that decide how the surface between your areas looks.

    5 min
  5. 05

    Read a cross-section

    start here

    Draw a section line across the site and read the ground profile beneath it, with the contour map alongside.

    6 min
  6. 06

    Slice and reshape areas

    start here

    Cut an area in two, open its outline, grow or trim it with a brush, offset a parallel copy, and combine shapes with join, subtract and fit.

    8 min
  7. 07

    Calculate cut and fill

    start here

    Compare your design to the ground as it stands and read how much soil is dug, brought in, or balanced on site.
