CadCompressCompacts the drawing database in memory (reclaims erased-entity slack).
CadCreateCreates a new, empty drawing and returns its handle.
CadDestroyDestroys the drawing and releases every entity, window and resource belonging to it.
CadExpandPre-allocates database capacity ahead of bulk entity creation.
CadFileNewNew empty drawing in-place (Vecad CadFileNew = CadPurge CAD_CLEAR_ALL): erase every entity, reset dirty + filename.
CadFileOpenLoad a DXF into the document (merges into the current contents).
CadFileOpenMemLoads a drawing from an in-memory, NUL-terminated DXF buffer.
CadFileSaveSave to the stored filename (set on open / save-as / CadPutFileName).
CadFileSaveAsFile save as.
CadFileSaveMemDXF to a memory buffer; returns the byte size (copies up to MaxSize).
CadFireLoadSaveEventHost-driven file load/save progress notification (Vecad CadFireLoadSaveEvent): the host calls this to drive the LoadSave callback (mode 0 = load, 1 = save) — e.g.
CadGetNumEntitiesLast-error reporting (Vecad CadGetError/ErrorStr).
CadGetVersionLibrary version: returns a numeric version + writes a version string.
CadRegenRegenerate = repaint the OpenGL view (yucad renders analytically, so there is no GDI display-list to rebuild — an update() is the equivalent).
CadUpdateRedraws the drawing in all attached windows — call after adding or editing entities.
Window & OpenGL View — 54
CadCWCreateCreates the command window inside a host panel.
CadCWDeleteDisable the command window (Vecad CadCWDelete): hide it and unlink it from every view so input stops routing there.

CadNavCreateNavigator overview panel embedded in the host (Vecad CadNav*).
CadNavGetParamReturns a navigator-panel parameter.
CadNavResizeResizes the navigator panel to its host area.
CadNavReturnFocusWhere the navigator returns keyboard focus to after the user drives it (so typing lands back in the host's CAD window, not the aerial view).

CadPenSelectorCreatePen selector create.
CadPutWindowSets the value of the host window.
CadShowBlockDialogVecad CadShowBlockDialog — modal block manager (BlockListPanel in a QDialog, mirroring CadShowLayerDialog).

CadShowOptionsDialogVecad CadShowOptionsDialog — display / object-snap preferences.
