2D Scene Items
2D Scene items represent an isolated linked 2D obeject. Currently 2D Scene items
are only line strips. They implement IStrip and
IStripTopol interfaces.
See the overlays topic about creating and
editing 2D scene items at runtime in Direct User Access mode.
To access a 2D item call
IModel_KC.GetItem() to obtain IItem
of the object. Query IStrip and
IStripTopol from the IItem.
Use IStrip.GetElement(i, False) to access i-th
point of the segment strip. Use IElement.GetParam(k)
to obtain k-th coordinate of the point. k is expected to be 0 for x or 1 for y.
Similarily, use IElement.SetParam(k, val)
to modify the coordinate.
Use
IStripTopol.Add() to add new points to
the strip. Use
IStripTopol.Break() to insert a new
point. Use IStripTopol.Add() to delete segment or point
