- V8 models are placed relative to their global origin (model header). - A V8 model's extent is the union of its elements' stored ranges; a V7 model's text box is one text height tall. - Files without a colour table use the standard DGN default table; colour 255 is read from the table's background entry. - Colours from a file's colour table follow the background: near-white colours swap with it, and over non-black backgrounds some shades drop a step. - DGN contrast pulls towards a pivot taken from the model's own colours, after the fade, which is blended into the background first. - Shared cells are read through their full 3D placement, so tilted instances and 3D definitions are drawn in plan. - Deleted V8 elements are skipped; lines along the model's extent stay in the raster.
