1. Create the kerbs from contours

First of all, turn the Layer Guidelines > Zone contours on since you will use these curves to generate the kerbs.

  1. Run the Dwarf wall/Hedge command (_laPartition laPartition ) to generate the kerbs of the project. The Dwarf/Hedge insert dialog box will appear (Fig 1.)
  2. Choose the insert options (example values given below).
    • Thickness: 0.3m
    • Height: 0.15m
    • Justification: Right
  3. Click on the Material's tab and click on the Browse button if you want to  change the material assigned by default to this object. (i.e select one of the "stone" materials located in the following directory: C:\ProgramData\AsuniCAD\Lands\Rhinoceros\Textures\AccuRender\Stone). This material will be shown either when you shot a render as well as when choosing the "Rendered" display mode.

  5. Click OK button to close the dialog
  6. Pick the curves that enclose each one of the regions of the park as shown in Fig. 2, to generate the kerbs.

2. Create kerbs from polylines

Rather than selecting an existing curve, kerbs can be created drawing them in the model as if you were drawing polylines.

  1. Run the Dwarf wall/Hedge command (_laPartition laPartition ) again.
  2. Choose the object settings and click OK to close the dialog.
  3. Select the Polyline option in the command line.
  4. Specify the first and end points of the kerbs following the lines highlighted in Fig. 3.
  5. You can change the object alignment and insert parameters as you are inserting them in the model, from the Lands Edit Panel laEditPanel.

3. Edit the kerbs

Once the kerbs have been inserted, you can edit their width, height, alignment or the material.

  1. Select one of the kerbs created.
  2. From the Edit panel laEditPanel, change the justification to Left.
  3. Change the height if you want to see different results.
  4. Play with the Smothness slider in order to get smoother results for those kerbs created from curved segments.
  5. Change the material assigned by default from the Material's tab.
  6. In case the Adjust button laElevateToTerrain Button in the command line was enabled when you created the kerb, it will be inserted automatically projected on the terrain surface. To do not adjust it to the terrain, select the kerb and from the Edit section of the Edit Panel laEditPanel, select Do not adjust to terrains option.

4. Create the kerbs with a different section profile

In case you wish to create the kerbs with a non rectangular profile, then you need to use the Path command instead:

  1. Select one of the kerbs created before (for example the one in the region #1) and delete it.
  2. Draw a polyline Polyline withe shape of the desired kerb section. Draw it on the Top viewport, aligned with the XY axis, as shown in Fig. 3.

  4. Run the Path command (_laPath laPath). The Path insert dialog will appear (Fig. 4).
  5. click on the "Select" button. The insert dialog will momentarily hide until you pick a curve for the path profile. Choose the one you have just drawn. (Alternatively you can select the "Pick by Point" button to draw the path profile in situ).
  6. Set the Justification to Bottom - Right.

5. What to do in case the kerb has been created in the wrong direction

There are two ways to correct this:

  • A. Change the direction of the curve used for the path axis, using the _Flip command Dir. Delete the wrong kerb and create it again using the flipped curve.
  • B. Mirror the profile curve used for the path section with the _Mirror command Mirror. Take the ZY plane as the mirror axis. Then delete the old kerb and created it again using this mirrored curve as the path section profile.
