* the class DS_DATA_ITEM (and DS_DATA_ITEM_TEXT) defines
* a basic shape of a drawing sheet (frame references and title block)
* Basic shapes are line, rect and texts
2021-02-22 23:47:17 +00:00
* the DS_DATA_ITEM coordinates units is the mm, and are relative to
* one of 4 page corners.
*
* These items cannot be drawn or plot "as this". they should be converted
2021-02-22 23:47:17 +00:00
* to a "draw list" (DS_DRAW_ITEM_BASE and derived items)
2021-02-22 23:47:17 +00:00
* The list of these items is stored in a DS_DATA_MODEL instance.
*
* When building the draw list:
2021-02-22 23:47:17 +00:00
* the DS_DATA_MODEL is used to create a DS_DRAW_ITEM_LIST
* coordinates are converted to draw/plot coordinates.
* texts are expanded if they contain format symbols.
* Items with m_RepeatCount > 1 are created m_RepeatCount times
*
2021-02-22 23:47:17 +00:00
* the DS_DATA_MODEL is created only once.
* the DS_DRAW_ITEM_LIST is created each time the drawing sheet is plotted/drawn
*
2021-02-22 23:47:17 +00:00
* the DS_DATA_MODEL instance is created from a S expression which
* describes the drawing sheet (can be the default drawing sheet or a custom file).
