  6. Assign a colour to each parcel.

  7. Press OK to accept.

8. In the Block Model panel on the right, toggle eye icon to show blocks and from the Shading dropdown select the blocks shading you have created - Materials (Note that custom shadings are shown in bold orange, while standard shadings are shown in normal black).

Select bench(es) from the tree on the left to display the viewport and review the result.

Colors assigned for block shading can be seen in the Legend (bottom right, below the viewport).

Creating a complex custom shading

  1. Select the gear icon next to the Shading dropdown. This opens the configuration dialog.

  2. Press the blue plus icon to add a new shading set.

  3. Rename the shading to "Ranges".

  4. Select the Complex tab to open the code editor.

  5. Paste in one of the sample code snippets located below.

  6. Press the Test button to make sure your code is correct. Any errors found will be shown in the Errors panel and won’t let you to proceed.

  7. Fix any errors detected, run test again and press OK to accept.
