igds_type: igds_solid
Solids correspond to IGDS element types 2, 6, and 14.
Solids correspond to the grouped shapes in MicroStation. Solids consist of polygons or donut polygons. When a donut polygon is written out as a solid, all holes are output with the hole bit turned on, and are grouped together with the enclosing polygon. Groups are created in the Design file by creating an unnamed cell header element, and making each shape in the donut polygon a member of the group.
If the reader parameter Expand Unnamed (Group Hole) Cells checkbox is ticked, then unnamed cell components are output but the cell header itself is not output. In this case, donut polygons will not be formed from member shape elements. All member elements will retain their original colors. If it is not ticked (the default), then the cell is not exploded into its components and only the cell header is output. Donut polygons may be formed if multiple intersecting polygons existed.
If a solid consists of polygons without holes, then it is written out as igds_shape.
Solids are always filled, and accept an additional parameter to define the fill color. Holes within a solid will not be filled with the color.
The IGDS file format imposes a limit on the number of coordinates which can be present in a solid. This limit is around 16,000 for two-dimensional IGDS files, and around 10,000 for three-dimensional IGDS files. If a solid with more than an allowable number of coordinates is encountered, it is rejected and a message to that effect is logged to the FME log file.
Solid elements have the following attributes:

igds_fill_color.red |
Reader only |
The fill’s red color intensity, as determined by looking up the fill color index in the color table. Range: 0..255 |
|
igds_fill_color.green |
Reader only |
The fill’s green color intensity, as determined by looking up the fill color index in the color table. Range: 0..255 |

igds_fill_color.blue |
Reader only |
The fill’s blue color intensity, as determined by looking up the fill color index in the color table. Range: 0..255 |
