Surfaces, balconies and railings

Updated 6 min readWorks without an account

A surface is a flat area you draw like a room: a terrace, a path, a plot or a hole in the floor. A balcony is a surface with a railing on its open edges, and a railing can also stand on its own.

Draw a surface or balcony

The More tools menu open in the tool dock
  1. Step 1: Open More tools

    Click More tools in the tool dock, or press U to start a surface straight away.

  2. Step 2: Pick Surface or Balcony

    Click Surface for a terrace, path or cutout, or Balcony for a slab with a railing.

  3. Step 3: Choose what to draw

    While the tool is on, the Draw bar at the bottom centre of the plan switches between Floor, Cutout and Balcony. A touch-only phone or tablet has no bar: draw the shape, then switch it to Cutout or Balcony in its properties.

  4. Step 4: Draw the shape

    Drag for a rectangle, or click its corners. Click the first corner, double-click or press ↵ to close it. Backspace removes the last corner.

Surface types
TypeWhat it is
SurfaceA terrace, patio, path or plot. It has a finish, a thickness and a height above the floor in 3D.
CutoutA hole in the floor under it, for a stairwell or a double-height space. It is hatched on the plan and opens the floor in 3D.
BalconyA slab at this floor’s level, with a railing along every edge that isn’t against a wall.

Surface properties

Select a surface and press ↵ for All properties. A cutout has no Finish or 3D section, since it is a hole. Lengths show in the project’s units; this guide gives them in cm. For how a raised or sunken surface relates to the storey floor, see Heights and levels.

  • Drag a corner to reshape it, and double-click an edge to add a corner. A picked corner can be removed with Remove corner; a surface needs at least three.
  • Area and Perimeter are read only. When rooms cover part of a surface, the properties split the area into Outside rooms and Under rooms.
  • Changing a surface into a balcony adds the default railing and makes the slab at least 15 cm thick.
  • The Plan summary (⌥3) lists the floor’s Surfaces with a colour swatch, the kind and the area, under their total area (cutouts left out). Click one to select it.
  • Right-click a surface for Edit corners, Kind ›, Duplicate, All properties and Delete. With a corner picked, the menu offers Delete corner and Delete surface.

Balconies

A new balcony has a 15 cm slab in Ceramic tile, and a Glass panels railing 100 cm high with posts every 120 cm. The railing runs along every edge that isn’t against a wall.

  • A railing lower than your building code’s guard height gets a warning that it is too low for a balcony guard. With the generic rules that height is 90 cm; a named code cites its own figure.
  • When no door opens onto the balcony, Access says No door opens onto this balcony yet. Click Add a balcony door to put a sliding door in the wall the balcony is against, opposite its middle. The new door is selected.
  • A balcony keeps the surface’s Name, its type switch and Finish above these.

Free-standing railings

  1. Step 5: Pick Railing

    Press E, or choose Railing in More tools.

  2. Step 6: Click its points

    Click each point along the edge. Each new segment turns in steps of the Angle step setting (15° by default) from the last point; hold ⌥ to draw at any angle. Click the last point again, double-click, right-click or press ↵ to finish. A railing needs at least two points.

  3. Step 7: Set its style

    In its properties pick the style, the height and Post spacing. Stands above floor raises it onto a raised terrace.

  4. Step 8: Reshape it

    Drag a point to move it, or double-click a segment to add one.

Questions

How do I make a double-height living room?

Go to the floor above and draw a Cutout over the living room. It opens that floor in 3D.

Does a balcony count in the floor area?

No. The plan summary lists open balconies and terraces apart from the rooms.

How do I raise a deck above the ground?

Select the surface and set Raise from floor in its 3D section. Level adds to the raise, for a sunken or raised split level.

How do I make a balcony railing taller?

Select the balcony and type a new Height under Railing. It can be 20 to 300 cm.
