Add and edit parcels

You can add parcels to a plan by drawing them manually. You can also merge, split, subtract a path, and retire parcels, and you can define their edge orientation in development mode when editing a plan. These actions happen within the Edit Geometry tool

Add a parcel

To add a parcel by drawing its geometry, complete the following steps:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to access development mode.
  3. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Add geometry button Add geometry.

    A drawing interface appears.

  4. Click the map to draw the boundaries of the new parcel. Double-click when you are finished.

    The OK button becomes available and the new parcel turns orange.

  5. Note:
    Parcels cannot overlap. Overlapping parts are automatically trimmed.
  6. Click OK.
Note:

Instead of drawing parcels manually, you can add them as a layer in the data manager or in the plan configuration. This allows you to upload all parcels in a city as a feature layer published to your ArcGIS Online organization. See Add and configure layers and Configure a design plan for details.

Select parcels

Click a single parcel to select it in the view. To select multiple parcels, press the Shift key while clicking the parcels or use one of the Advanced Selection tools.

Use freehand selection

To select parcels using the Freehand selection advanced selection tool, complete the following steps:

  1. Open the Plan editor.
  2. Click the Advanced Selection button Select on the vertical toolbar between the view and the side panel.
  3. Click the Freehand selection button Freehand selection on the blue header bar.
  4. Drag the pointer to draw freehand in the view.
    • Draw a line to select all parcels intersecting that line.
    • Draw a polygon to select all parcels intersecting that polygon.
  5. Click Done to close the Freehand selection tool and continue working with the selected parcels.

Use rectangle selection

To select parcels using the Rectangle selection advanced selection tool, complete the following steps:

  1. Open the Plan editor.
  2. Click the Advanced Selection button Select on the vertical toolbar between the view and the side panel.
  3. Click the Rectangle selection button Rectangle selection on the blue header bar.
  4. Drag the pointer to draw a rectangle.
    • Drag the pointer from right to left to select parcels that intersect the rectangle.
    • Drag the pointer from left to right to select parcels in the rectangle.
  5. Click Done to close the Rectangle selection tool and continue working with the selected parcels.

Use select by feature

To select parcels using the Select by feature advanced selection tool, complete the following steps:

  1. Open the Plan editor.
  2. Click the Advanced Selection button Select on the vertical toolbar between the view and the side panel.
  3. Click the Select by feature button Select by feature on the blue header bar.
  4. Select a polygon feature in the view to use to select the parcels.

    You can only select the top visible polygon layer in the view. Use the options menu to turn off polygon layers that you don't want to use for selecting parcels.

    Parcels that intersect with the selected polygon feature are selected.

  5. Click Done to close the Select by feature tool and continue working with the selected parcels.

Merge parcels

To merge parcels, complete the following steps:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to switch to development mode.
  3. Select two adjacent parcels.
  4. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Merge button Merge.
  5. Click the blue merge button on the Merge Selection dialog box to confirm the merge.

Once two parcels are merged, the assigned building type is generated across the entire parcel area.

Note:

There is no undo button for this action. Once two parcels are merged, you must divide them manually using the Split tool.

Split a parcel

To split a parcel, complete the following steps:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to switch to development mode.
  3. Select a large parcel.
  4. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Split button Split.
  5. Draw a polyline to split the parcel.
  6. Click the Split button in the header.

Note:

Start and end the polyline outside the target parcel while viewing the parcel from above. Click the 2D button at the lower right of the view to do so.

Subtract path

Complete the following steps to divide a parcel using a defined path width. This workflow is useful for parcels that are spilt by a street or other geometries that cause a single parcel to appear in two pieces.

  1. Open the Plan editor
  2. Click the Development button Development in the header to switch to development mode.
  3. Select a parcel.
  4. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Subtract path button Subtract path.
  5. Define the width of the path you will use to split the parcel.

    The width is the amount of space that will be left between each portion of your parcel after splitting.

  6. Draw a path to subtract from the selected parcel.
  7. Double-click to complete and click OK.
  8. Click Done to close the Edit Geometry tools.

Split a parcel into a grid

Complete the following steps to split a parcel into a grid:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to switch to development mode.
  3. Select a large parcel.
  4. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Grid button Grid.
  5. Split the selection.
    • Square Cells—Split into squared cells.
    • Honeycomb Cells—Split into hexagonal cells.
  6. Specify the grid cell size on the blue header bar.

    As you type a cell size, the grid pattern preview changes accordingly in the view.

  7. Specify the grid cell orientation on the blue header bar.

    As you edit the cell orientation, the grid pattern preview changes accordingly in the view.

  8. Click OK.

    The selected parcel is split into smaller parcels according to the specified grid configurations.

Retire parcels

You can delete parcels by retiring them. You cannot undo this action; however, you can add a new parcel over the area where the previous parcel was retired. To retire a parcel, complete the following steps:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to switch to development mode.
  3. Select the parcel you want to retire.
  4. Click the Edit geometry button Edit geometry on the workflow toolbar at the right of the view, and from the Edit geometry tools in the header, click the Retire button Delete.

    A confirmation message appears.

  5. Click Retire to delete the parcel.

Edit parcel edges

You can calculate the orientation and street adjacency attributes of parcel edges in ArcGIS CityEngine or manually define them while editing a plan. These attributes are used when developing a parcel—for example, when adding tiers and setbacks or skyplanes. To edit them while editing a plan, complete the following steps:

  1. Open the Plan editor.
  2. Click the Development button Development in the header to switch to development mode.
  3. Select the parcel you want to retire.
  4. Click the Edge orientation button Orientation on the workflow toolbar at the right of the view.

    The Editing parcel edges options appear at the top of the view.

  5. Click the edge you want to assign an orientation to, or select multiple edges using the Lasso select or Rectangle select tool or press the Shift key while you click the edges.
  6. Select the orientation (front, side, or rear) and specify whether it is an interior or street edge.
  7. Click Done to finish the edge orientation definition.
Note:

To learn more about calculating the orientation and street adjacency attributes in ArcGIS CityEngine, see the corresponding topic in the CityEngine documentation.
