None

For less complex designs, and when none of the other types is necessary, this provides a good default solution. Select None when:

●       There is no need for the hardscape to have a thickness for 3D views or sections.

●       There is no need for components, for either rendering or reporting purposes.

●       A particular style of hardscape or manufacturer is not required.

●       The hardscape does not need to serve as a modifier for a site model.

●       Slab drainage functionality is not needed.

●       The slab can remain completely planar.

●       The slab does not need to automatically match the elevations of any other objects.

Slab

Select Slab when:

●       The hardscape needs a thickness or components for 3D views or sections.

●       Components are required for rendering or reporting purposes.

●       The hardscape needs to slope in one planar direction.

Slab Modifier (Top/Bottom)

Select Slab Modifier when:

A Slab type is needed, and in addition, the hardscape will serve as a site modifier, with the site model’s surface aligning with the top or the bottom of the slab

Texture Bed Modifier

Select Texture Bed Modifier when:

The hardscape is used a site model texture bed modifier, changing the texture on part of the site model; see Creating a texture bed

Slab Drainage

Select Slab Drainage when:

The hardscape needs to support a drainage system or you need to create simple non-planar geometry for the hardscape

Aligned Slab

Select Aligned Slab when:

The hardscape needs to vertically match the horizontal edges of certain geometry, including adjacent roadways, hardscapes, massing models, 3D polygons, landscape areas, walls, and pad or pad with retaining edge site modifiers (with site model modification when the modifier aligned slab is selected). Aligned slabs are complex, non-planar hardscape types that can also be modified with vertical profiles, stake objects, and grade objects.

Aligned Slab Modifier (Top/Bottom)

Select Aligned Slab Modifier when:

An Aligned Slab type is needed, and in addition, the hardscape will serve as a site modifier, with the site model’s surface aligning with the top or the bottom of the slab
