Add and edit parcels

You can add parcels to a plan by drawing them manually. You can also merge, split, and retire parcels, and you can define their edge orientation in development mode when editing a plan.

Add a parcel

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

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

    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 your 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. 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 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 button in the vertical toolbar between the view and the side panel.
  3. Click the Freehand selection button Freehand button in 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 button in the vertical toolbar between the view and the side panel.
  3. Click the Rectangle selection button Rectangle button in 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 button in the vertical toolbar between the view and the side panel.
  3. Click the Select by feature button Select by feature button in the blue header bar.
  4. Select a polygon feature in the view that you want 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 Development in the header to switch to development mode.
  3. Select two adjacent parcels.
  4. Point to the Add button Add geometry button on the workflow toolbar at the right of the view, and from the popover, click the Merge button Merge button .
  5. Click the blue merge button on the Merge Selection dialog box to confirm this action.
  6. Note:
    The appearance of the button to access the geometry edit popover on the workflow toolbar changes according to the previously selected geometry editing tool. It now displays the Merge button Merge button.

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

Note:

There is no undo button for this action. Once two parcels have been 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 Development in the header to switch to development mode.
  3. Select a large parcel.
  4. Point to the Add button Add geometry button on the workflow toolbar at the right of the view, and from the popover, click the Split button Split button.
  5. Draw a polyline to split the parcel.
  6. Click the Split button in the header.
  7. Note:
    The appearance of the button to access the geometry edit popover on the workflow toolbar changes according to the previously selected geometry editing tool. It now displays the Split button Split button.

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.

Split a parcel into a grid

  1. Open the Plan editor.
  2. Click Development in the header to switch to development mode.
  3. Select a large parcel.
  4. Point to the Add button Add geometry button on the workflow toolbar at the right of the view, and from the popover, click the Grid button Grid button.
  5. Specify the grid cell size in the blue header bar.

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

  6. Click Ok

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

    Note:
    The appearance of the button to access the geometry edit popover on the workflow toolbar changes according to the previously selected geometry editing tool. It now displays the Grid button Grid button.

Retire parcels

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

  1. Open the Plan editor.
  2. In development mode, click the parcel you want to retire to select it.
  3. Point to the Add button Add geometry button on the workflow toolbar at the right of the view, and from the popover, click the Retire button Delete button.

    A confirmation message appears.

  4. Click Retire to delete the parcel.
  5. Note:
    The appearance of the button to access the geometry edit pop-up on the workflow toolbar changes according to the previously selected geometry editing tool. It now displays the Retire button Delete button.

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. In development mode, select a parcel.
  3. Click the Edge orientation button Orientation button on the workflow toolbar at the right of the view.

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

  4. 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.
  5. Select the orientation (front, side, or rear) and specify whether it is an interior or street edge.
  6. 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 City Engine documentation.
