Create LANDSurface

Multiple ways to create LANDSurface

There are several ways to go about creating a LANDSurface, but each of them involves selecting:

• three reference points (minimum).
• the area for the LANDSurface.

LANDSurface based on selected objects

1. Go to LAND4 Palette/Category.
2. Set Category for your new LANDSurface.

3. Select a minimum of three existing reference points among existing:
   • Spot Levels,
   • Ridge Lines, or
   • Contour Lines.
4. Go to:
   1. LAND4 Palette/LANDSurfaces, or
   2. LAND4/Group Palettes/Show LANDSurface Palette.
5. Press Create LANDSurface button.
6. Select area for LANDSurface:
   • use the Magic Wand, or
   • draw a closed polygon – LAND4 uses the ARCHICAD Polyline tool.
7. The Create LANDSurface dialog opens and offers the possibility to add objects to/remove objects from a selection set.
   Note! Objects from all LAND4 Categories can be added.
8. To create LANDSurface, press green tick in dialog.

LANDSurface based on selected area

1. Go to LAND4 Palette/Category.
2. Set Category for your new LANDSurface
   In the example below, the Category is set to “LAND4 New”.

3. Press Create LANDSurface.
4. Select area for LANDSurface:
   • use the Magic Wand, or
   • draw a closed polygon – LAND4 uses the ARCHICAD Polyline tool.
5. Now two things happen:
   • objects belonging to the selected LAND4 Category and impacting the triangulation of the selected area will automatically be enhanced, and
   • the Create LANDSurface dialog opens and enables you to add objects to/remove objects from a selection set.
     Note! Objects from all LAND4 Categories can be added.

6. To create LANDSurface, press green tick in dialog.
