Modelling:
the default zoom view () and direct point edit () keyboard shortcuts are now () and () respectively to make way for two very important new shortcuts:
· modelling actions like move, scale, or rotate no longer decide what to transform (objects or selected points) based on the point selection; now always objects are transformed, until the user switches explicitly to points using (while can be used to switch back to objects)
· the point transformation state is displayed in the modelling mode icon by a little red dot
· the mark is now reset on double
· direct point editing now uses the point selection instead of an own pointer;
· thus, it now works with multiple selected objects, and one may apply
· coordinate values to multiple (selected) points
· the Revolve tool object now supports arbitrary ThetaMax values in B-Spline mode (Sections != 0)
· o added Arc and Radius parameters to create closed B-Spline curve tool
· added Radius, TMin, and TMax parameters to NCircle object creation dialog
· added modelling action to snap the selected points to the mark new shortcut )
· added modelling action to snap the selected objects to the mark new shortcut )
· added view action to pan the view to the mark (new shortcut )
· to avoid clashes, collapse and explode actions have new default keyboard shortcuts: and
· the find u modelling action now works with provided objects, and is more exact
added find uv modelling action that finds the u and v parameters for a picked point on a NURBS surface; invoke via new view shortcut:
· added preference setting and facility to manage a global mark, if enabled, all views share a single mark; thus, one can set it in one view and use it in another
· improved order changes for periodic NURBS curves via the property GUI
· added "3DPVN" curve offset mode that offsets a curve along normals supplied via a primitive variable tag
· creating ExtrNC/ExtrNP objects via the main menu now automatically adds a remove property tag ("RP Transformations") to the created instance child
· so that the instance always follows the transformations of the surface the curve/sub-surface is extracted from
· NURBS curve clamping now works with half clamped curves and also with
· curves where there are multiple knots in the end region(s)
· NURBS curve clamping can now also clamp only one end of the curve
· NURBS patch clamping now works with half clamped patches and also with
· patches where there are multiple knots in the end region(s)
· NURBS patch clamping can now also clamp only one end of the patch the point insert/delete modelling actions now work with multiple selected objects
· several objects now support read only points, which can be selected and their coordinates inquired (for snapping/aligning or transformation purposes) but they can not be modified; the supporting objects are: Box, Sphere, Cylinder, Disk, Cone, Torus, Hyperboloid, Paraboloid, Extrude, Revolve

· GUI
· AutoFocus is now available (again) for single window GUI mode; here it manages the focus of internal widgets (views, tree, properties, console)
· Tool dialogs now display a more descriptive window name
· tree drag and drop now keeps the object selection intact and opens the target level
· starting modelling actions from the toolbox now also considers the AutoFocus preference setting, if enabled, the action is started in all views

Scripts/Scripting Interface:
· number conversion errors are now correctly detected and reported in all scripting interface commands
· added "-world" option to setPnt/getPnt commands (to transform coordinates from/to world space) renamed "-p" option to "-eval" for getPnt
· getPnt can now work with arbitrary object types (even from plugins) as long as they support single point editing; i.e. it now works with PolyMesh, SDMesh, and SDNPatch objects
· the "hSL" command has been removed from safe interpreters, use "sL" instead
· added a JavaScript interpreter plugin
· Script objects can now use arbitrary languages provided by plugins e.g. JavaScript)
· added a example Script object script (written in JavaScript) that creates a Polyhedron from a Conway notation ("polyhedron.js")

Documentation/Example Files:
· documentation of modelling actions enhanced with tables containing keyboard shortcuts and icons
