Develop a parcel

You can develop a parcel with a plausible building, you can leave the parcel as is, or you can remove an existing condition. A plausible building is a low level of detail (LOD1) schematic building. You can generate a plausible building automatically by assigning a building type to a parcel or you can create a plausible building by drawing individual building spaces. You can also edit the individual floors of an automatically generated building. In addition to drawing building spaces, you can also draw and edit surfaces.

Work with building types

When assigning a building type to a parcel, a plausible building is generated. The form of the plausible building is based on the underlying zoning or land-use parameters and the space-use types assigned to the building type. To generate a plausible future building on a parcel, all of the following are required:

  • The parcel must be located in a zoning or land-use boundary with sufficient parameters to define a plausible building (or at least parameters applied as overrides on the parcel).
  • The parcel must have a building type assigned with space-use types and a stacking plan for the floor plates of the building.
  • The parcel must have a valid combination of parcel shape, size, and zoning or land-use parameters; otherwise, a building may not be possible or feasible (for example, if a parcel is too small to support a large building).

Assign a single building type

To assign a single building type to a parcel, complete the following steps:

  1. Open the Plan editor.
  2. Click Development Development in the header to switch to the development mode.
  3. Ensure that the side panel on the right is expanded.
  4. Click a parcel in the view.
  5. Click the Modify drop-down menu in the Development on selected parcels section of the side panel and select Apply building type.

    The side panel lists the available building types. If you select a parcel with an assigned building type, it is highlighted in the list.

  6. From the Select building type side panel, click the building type name to assign to the parcel.

    The building is updated in the view.

Assign a building types mix

To assign a building types mix to multiple parcels, complete the following steps:

  1. Open the Plan editor.
  2. Click Development Development in the header to switch to the development mode.
  3. Ensure that the side panel on the right is expanded.
  4. Select the parcels to which the building types mix will be assigned.

    To select multiple parcels, press the Shift key while selecting parcels or use the Advanced Selection tool Select on the workflow toolbar at the right of the view.

  5. Click the Modify drop-down menu in the Development on selected parcels section of the side panel and select Apply multiple building types.

    The Apply multiple building types side panel appears.

  6. Use the Add Building Type drop-down menu in the side panel to add building types.
  7. Define a percentage for each building type.

    • The percentage represents the probability with which the corresponding building type is assigned to one of the selected parcels.
    • If the sum does not equal 100 percent, the percentage values are redistributed automatically to equal 100 percent when you click the Apply multiple building types button.

  8. Click Apply multiple building types at the bottom of the side panel.

    The view is updated and shows the parcels with the configured building types mix.

Note:

  • The assignment of the building types changes every time you apply the same mix of multiple building types.
  • In the allocation process, only building types that comply with the underlying zoning or land-use regulations are applied to the selected parcels. This may affect the resulting building types mix.

Work with spaces and surfaces

Working with spaces and surfaces allows you to do the following:

  • Edit the building spaces of generated plausible buildings.
  • Draw additional spaces on or next to generated plausible buildings.
  • Design custom buildings by drawing new building spaces.
  • Improve the surroundings of the developments with surfaces.

Like building spaces, surfaces have a space-use type assigned and count toward metrics. Surfaces do not count toward zoning regulations such as coverage or number of dwelling units. They can count toward FAR if this is specified in the surface settings. Surfaces are always draped to the terrain and have no height.

Draw new building spaces

Complete the following steps to draw new building spaces:

  1. Open the Plan editor.
  2. Click Development Development in the header to switch to the development mode.
  3. Make sure the side panel on the right is expanded.
  4. Select the parcel where you want to draw a new building space.
  5. Click the Edit Spaces tab in the side panel.

    The blue header bar with the spaces editing tools appears.

  6. Use the Toggle demolition of existing buildings and trees tool Toggle demolition of existing buildings and trees to mask the existing buildings and trees on the parcel.
    Note:

    If a parcel is demolished, existing metric values on this parcel will be subtracted from the metric values generated by the new development. See Work with metrics to learn more about metrics.

  7. Click Draw new building space Draw new building space.
  8. Draw a building space on the map.
  9. Double-click to complete the drawing.
  10. Add underground spaces.

    Click the menu button Menu Button and switch to Underground. Adapt the view of the scene and add spaces by drawing from the underground.

    Note:
    Alternatively, you can create underground spaces by moving the building below the ground level. Use the Edit building elevation tool described in the Edit building spaces section below.
  11. Edit the building space according to your requirements using one of the options listed in the Edit building spaces section below.

Note:
You can also draw building spaces on top of and next to each other. Building spaces that do not share vertexes or edges are considered separate buildings. Use the snapping options to ensure that the spaces of a building are correctly aligned.

Draw new surfaces

Complete the following steps to draw new surfaces:

  1. Open the Plan editor.
  2. Click Development Development in the header to switch to the development mode.
  3. Ensure that the side panel on the right is expanded.
  4. Select the parcel where you want to draw a new surface.
  5. Click the Edit Spaces tab in the side panel.

    The blue header bar with the surface editing tools appears.

  6. Use the Toggle demolition of existing buildings and trees tool Toggle demolition of existing buildings and trees to mask the existing buildings and trees on the parcel.
    Note:

    If a parcel is demolished, existing metric values on this parcel will be subtracted from the metric values generated by the new development. See Work with metrics to learn more about metrics.

  7. Click Draw new surface Draw new surface.
  8. Draw a surface on the map.
  9. Double-click to complete the drawing.
  10. Edit the surface according to your requirements using one of the options listed in the Edit surfaces section below.

    The blue header bar with space editing tools appears.

  6. On the highlighted parcel, click a building space.
  7. Choose from the spaces editing tools according to your requirements:
    • Transform Transform—Scale and rotate the selected building space. The scaling also impacts the congruent building spaces above the selected space. The rotating impacts all building spaces above the selected space.
    • Edit vertices Edit vertices—Add vertices and move and remove existing vertices. The tool impacts the selected building space as well as congruent spaces above it.
    • Move edges Move edges—Push and pull the edges of the selected building space. The tool impacts the selected building space as well as congruent spaces above it.
      Note:

      This tool is not supported on devices with touch input.

    • Edit building elevation Edit building elevation—Vertically align the entire building that the selected building space belongs to.
      Note:

      If you move the building below the ground, the tool automatically updates the floor numbers and the building height. Uncheck the Change ground floor check box to disable the update of the ground floor (for example, to adjust the building in uneven terrain).

    • Duplicate Duplicate—Duplicate the currently selected building space.
    • Remove Remove—Remove the currently selected building space.
  8. Edit the parameters of the selected building space in the Selected spaces section of the Edit spaces tab in the side panel. Choose from the following options:
    • Space Use Type—Change the type of the selected building space.
    • Floor Height—Change the floor height of the selected building space.
    • Net Area Factor—Change the net area factor of the selected building space.
    • Counts towards GFA/FAR—Decide whether the area of the selected building space counts toward the GFA and FAR calculations.
  9. Click Done when you finish your edits.
Note:

If a building floor consists of multiple building spaces, changing the height of one building space automatically changes all other building spaces on this floor.

Generate buildings from footprints

You can generate building spaces by uploading building footprints. See Work with spaces and surfaces to learn how to modify and edit building spaces. Complete the following steps to generate building spaces from footprints:

  1. Open the plan editor.
  2. Expand the drop-down menu named after the plan and select Configure.

    The plan configuration opens to the general plan settings tab by default.

  3. Select Spaces from the Layers drop-down menu.
  4. Select the scenario that will receive the building spaces from the scenario drop-down menu.
  5. Click Upload footprints.

    The portal item picker appears.

  6. Click the building footprints layer you want to use and click OK.

    The import settings appear.

  7. Select the building type to be applied to the imported footprints.

    The buildings being generated ignore the underlying zoning or land-use parameters. For every space-use type that is part of a building type, the maximum number of floors is built as configured on the building type.

  8. Click OK.

    Building spaces are only being generated for building footprints that are completely within the study area and whose centroid intersects with a parcel.
