What's new

History of the LinceCAD versions, from the most recent to the oldest. The installed version is shown in the window title and in ABOUT.

1.0.0 (coming): bug fixes

Aliases as in AutoCAD 2027; with the English interface the Spanish aliases no longer apply, and _ plus an English alias works in any language. See Command aliases.
LINE: Undo also removes the segment, not only the point.
OPEN, SAVEAS (and its versions), RECOVER and NEW follow FILEDIA and, in scripts, SCRIPT, AutoLISP and the API, ask for the file on the command line. SAVEAS offers DWG, DXF and DWT in the dialog.
ORTHO, OSNAP, SNAP, POLAR, LWDISPLAY and PAN can be typed; SETVAR, scripts and AutoLISP read and change OSMODE, ORTHOMODE, SNAPMODE, AUTOSNAP, POLARANG and GRIDMODE, and getvar/setvar see every SETVAR variable.
In evaluation mode the query palettes can be opened (PROPERTIES, LAYER, XREF…).
MESHREFINE makes the smoothed shape the mesh; ARRAY offers PAth; RECTANG previews in the UCS; texts and help fixed.
