About Surfaces

To display your plan realistically, you can apply surfaces to your elements. Surfaces contain color, texture and light effects. Surfaces can be displayed in the 3D Window, Section/Elevation/IE and 3D Document windows, and in PhotoRenderings.

The ARCHICAD Library contains hundreds of preconfigured surfaces for every need. You can also access additional surfaces on BIM Components, using the Surface Settings dialog box.

See Create, Load and Share Surfaces (All Engines).

Surfaces can be created or modified in the Surface Settings Dialog Box (Options > Element Attributes > Surfaces). Surfaces defined here are then assigned to construction elements through Building Materials (which include a Fill and a Surface).

Once you assign a Building Material to an element, the element will use the Surface of the Building Material. You can, however, override the Surface at the element level (use either Surface Painter or the Override Surface controls in the Model panel of element settings).

See Override Surfaces With Surface Painter and Override Surfaces in Element Settings.

Some surfaces have vectorial hatching and/or textures as part of their definition, as indicated by icons. This surface, for example, can display either a vectorial hatching or a texture:

Assign a Vectorial Hatching to a Surface

Vectorial Hatching is a vectorial fill pattern used with a Surface. In the Vectorial Hatching panel of Surface Settings, choose a vectorial hatching from one of the project’s defined vectorial fill types.

See Surface Vectorial Hatching Panel (Basic Engine).

Note: When assigning a 3D Vectorial Hatching in the Surfaces dialog box, you can access only fills defined as Cover Fills.

Assign a Texture to a Surface

Textures are image files that can be assigned to surfaces to give them a more realistic look and feel. They are displayed in PhotoRenderings, and in the 3D window using the OpenGL Engine.

By default, many ARCHICAD surfaces have textures assigned to them (such surfaces will have a texture icon next to their name.) You can load additional textures from the ARCHICAD library, or load other custom images. Textures are assigned and edited in the Texture Panel of Surface Settings.

For information on using textures with CineRender surfaces, see Textures (CineRender Surfaces).

Display of Vectorial Hatching and Textures in 3D Window

To display Vectorial Hatching:

use the Vectorial Engine (View > 3D View Options)

the Vectorial Hatching checkbox in 3D Styles must be On

To display Textures:

use the OpenGL engine (View > 3D View Options)

make sure the Textures box is checked in OpenGL options (click Advanced Options from 3D Styles).

Note: You can customize the orientation and origin of textures in 3D views.

See Align 3D Texture.

Note on the GENERAL Surface

The GENERAL Surface is only available for Building Materials, Element Surfaces and GDL. When a Surface is defined as “GENERAL”, it will display a solid color based on an Elements’ Uncut Line Pen.

By default, this General Surface will be assigned to new Building Materials and to new Surface parameters added within GDL. It is used to avoid assigning to an incorrect Surface or creating a missing attribute. It is hard coded into ARCHICAD and is not available in the Surface Settings dialogue or Attribute Manager.
