2.1 Zonify

(Download the Bamboo_Park_Tutorial_2.1.3dm file in order to start the tutorial from this chapter.)

The document is ready to start modeling the project. The first thing to do will be defining the areas of intervention.

Zoning insert dialog

Fig. 1. Zoning insert dialog

1. How to insert a zone

  1. Run the Zonify command (_laZonify laZonify) to insert a zone.
  2. Select the "Pick inner point" option in Command line (default) and click inside a closed boundary of 2D curves (i.e. the area inside the big rectangular building footprint (1. Main building zone), fig.2). The zoning dialog will appear. (fig.1)
  3. Select the Zone parameters in the zoning dialog. The Zone tab lets you define the zone label's name, and hatch pattern attributes for its 2D representation. The Material's tab lets you choose a material for the zone surface.
  4. Pick a point in the model to insert the Zone label.

2. Insert a zone from multiple regions

Zones can be created from multiple regions using the Limits option in the Command line. You can use this method for the 2. Bamboo Zone area, which includes 6 regions. (Fig. 2)

  1. Run the Zonify command (_laZonify laZonify) and select the Limits option in the command line.
  2. Select all boundary curves that enclose the regions of this zone. (You can find these curves in the Layer Guidelines > Zone Contours). Click ENTER or right click to finish the selection. The Zone insert dialog will appear.
  3. Define the Zone name and 2D representation settings, and click OK to close the dialog.
  4. Insert the Zone label.

How to create the boundary curve from a region?

In case of the Water Zone area, you can create a boundary curves for each region of this zone.

  1. Activate the Guidelines > Zone Contours as the current layer.
  2. Run the _CurveBoolean command CurveBoolean.
  3. Select all curves in the drawing.
  4. Click inside the regions of the Water Zone area to generate the 3 boundary curves.
  5. Now you can insert the zone for the Water Zone using the Limits option and picking these 3 boundary curves.

Note: Zones with the same name, either if their labels are displayed or not, will sum up their areas together when later on you create the list of zones.

3. Insert all zones

Insert the rest of zones, as indicated in the fig.2.

Choose the most convinient insert option (Pick inner point or Limits) in each case.

  1. Main building
  2. Bamboo zone
  3. Water zone
  4. Green zone
  5. Outside building zone
  6. Path
  7. Path
  8. Tree vegetation
  9. Tree vegetation
  10. Tree vegetation
  11. Focal point
  12. Green wall
  13. Green wall
  14. Lobby building zone

In case the Zone Label indicates the Area is 0, it means the region selected is open and therefore the area can't be calculated. Then you need to create a boundary curve or close the region with some additional line to insert a zone in that region.

4. Edit the zones

The zones inserted in the model can be edited from the Edit area of the Lands Edit Panel laEditPanel, after selecting the Zone object (fig.3). There you can change the Hatch paramaters assigned to the zone area as well as the Label Parameters.

Zone Control Points

The limits of a zone and the position of the zone label can be edited through its control points.

  • Turn the zone points on: select the zone and run the _PointsOn command PointsOn (or hit F10 button).
  • Press ESC or right click on the Control Points icon to turn them off.
