Added:  On startup, L3DD now remembers its previous window size, location and configuration. 

Improved:  L3DD now looks for LIG, BMP, STL and DXF files in the appropriate folders beneath the program folder.  If not found, L3DD remembers the last folders manually navigated in the program. 

Changed:  The folders beneath the L3DD folder are now called 'BMP Files', 'CAD Files' and 'LIG Files'.

Improved:  The Weld Vertices command now removes any duplicate vertices within a face.

Improved:  Now clone or extrude a group of faces by using Ctrl-left click (clone), or Alt-left click (extrude), on a completed group selection.

Updated:  User manual updated.

Improved:  In most special cursor modes you can now left-click on completed group selections to simultaneously move/extrude/rotate the selection. 

Fixed:  In previous version, at least, the 'Precise Move' command did not work on a group selection.

Refined:  User manual edited and expanded.  A 'Special Cursors' section has been added.

Fixed:  Esc & Tab keys work again as intended to move faces normally, while vertices move radially.

Fixed:  Multiply & Divide move vertices radially.

Refined:  User manual edited and expanded a bit.

Enhanced:  The program's anticracking measures.

Added:  Create Frame command to make a convex polygon into a rectangular-sectioned framework.

Fixed:  Adding a component name after selecting the whole object would crash the program.

Changed:  Precision of the millimetre scale reported in the Plan View increased to two decimal places.

Fixed:  Field for entering no. of steps in 'Revolution Steps' dialog was too short -- lengthened.

Added:  Named components for grouping faces - e.g. columns in GreekTemple.lig.  Double-click on a member face to select the whole component.

Added:  Textures and colors that now stay with faces during editing and .LIG file saving or loading.

Added:  Enter or edit project title and description via a dialog that also shows project statistics.

Added:  Matrix Replication command that replicates selections according to a 1D, 2D or 3D matrix.

Added:  Edit Menu command to enter, edit or delete a named component.

Added:  Edit Menu command to select component.

Enhanced:  The Undo command now works with all decor changes.

Enhanced:  Data View now has a Component List and a column for component no. in the Face List.

Enhanced:  Texture file path names now stored in .LIG files, so that textures automatically reload.

Enhanced:  Add-Face command can now be used to edit existing faces, as well as add new faces.

Changed: Ctrl-Left Button now used to select hidden edges in Wireframe mode (was Shift-LB).

Fixed: A number of minor bugs in the program.

Updated: User manual/help system fully updated.

Enhanced:  Undo and Redo commands now act consistently following all Tools Menu commands.

Fixed:  Bug in Center on Origin/Y/GP commands.  No Selection now acts the same as 'Select All'.

Fixed:  A freeze bug that appeared immediately after loading .LIG files generated by version 3.23.  

Enhanced:  The Undo command is now multi-level.  >100 consecutive undos commonly available.  

Added:  A 'Redo' command in the Standard Toolbar that reverses all previous undos, one by one.

Added:  A 'Weld Vertices' command now in 3D edit toolbar -- unifies two or more selected vertices. 

Fixed:  A bug in the centring and 'Precise Move' commands when one vertex or edge is selected.

Fixed:  A bug preventing more than two faces or vertices being manually selected in rotate mode.

 User manual brought up to date.

Fixed:  A bug affecting the movement increment per keystroke, as specified in the 'Scale' dialog box.

Fixed:  A bug preventing full Plan View display if two or more vertices selected in 3D View. 

Fixed:  Bug in 'Rotate to Top & Bottom' commands. 

Added:  The ability to draw lines ('guy ropes') between two vertices -- just click on vertex 1, vertex 2, and then vertex 1 again.  Stored as 'faces' with only 2 vertices.

Added:  A Chamfer Command to the Tools Menu.  Can chamfer both vertices and edges, resulting in surprising transformations to some objects.

Added:  The ability to select multiple edges (with Shift-Left Mouse Button) so that they can be chamfered simultaneously.

Changed:  The selection of hidden edges in Wireframe Display Mode now uses Control-Left Mouse Button, rather than Shift-LMB.
