Types of Blocks

Individually, a block is one of three types: Mapped, Swept, or Free. See Blocking types. You may use the Map/Sweep control to convert the block type. See Setting a mesh type.

You may convert from Surface blocks to Volume blocks and vice versa using the Solidify and Detach Faces options in the Blocking context menu (right-click Blocking in the Structure tree). This may be useful for some cleanup of surface mesh before performing the volume fill operation.

• Any single blocking node in the Structure tree can contain either surface mesh or volume mesh but not both. To have both surface and volume meshes in your model requires you to use separate components for each.

• The Solidify conversion from surface to volume blocks updates the tree to show block type and number. Selecting a block in the tree will highlight the appropriate block.

  This option requires that the surface blocking forms a closed volume.

• The Detach Faces conversion from volume to surface updates the tree to show a single block for each face. Individual block faces may be selected in the tree.
