Version	Changes
3.2.0 - SharpCam 3D Pro	New command added: 'Face Milling' to the Machine menu and toolbar. This strategy allows the face milling of the supplied contours. Features include: Machine angle - manual or automatic. Oneway or both machining direction. Direct, arcs or spline between passes. Extension past contours. Support for 3D Connexion Space Navigator.
3.0.0 - SharpCam 3D Pro	New command added: 'Constant Cusp' to the Machine menu and toolbar. This strategy will create an equidistant cut pattern on the machining surfaces. New command added: 'Project Curves' to the Machine menu and toolbar. This strategy will produce Radial, Spiral, Offset and User Defined projected patterns. New command added: 'Flatlands' to the Machine menu and toolbar. This strategy is designed to machine true flat areas of a 3D Model. New command added: 'Pencil' to the Machine menu and toolbar. This strategy automatically detects the inlaying edges. A single tool path will be created along these edges. . New features added to 3D Roughing Rest Rough - Rough remaining material left by a previous larger tool. Adaptive roughing strategy - Ensures that the cutting conditions remain almost constant, which offers great improvements compared to conventional constant offset roughing strategies. The strategy avoids full-width cuts by constantly measuring the engagement volume of the tool with material and gradually removing material off the remaining stock. It guarantees stable load on the tool, which allows an increased material removal rate at higher feed rates and reduces the overall machining time. Ramping - Defines the lead-in motion for the rough tool path segments. Following types of ramps are available: Line, Helical, Zig-zag and Profile. Pilot Drilling - Specify previous drilling operation to be used for entry points. Material Stock Containment - Use the material stock to contain the toolpaths. Allows for efficient roughing by approaching from outside the material where possible. Gouge Check - Specify Models to be avoided. Silhouette Containment - Limits the machining area by the silhouette of the machining surfaces. Intermediate passes - Intermediate passes can be added to reduce the staircase effect. Machine Flatlands - Additional passes will be added to clear flat areas that would otherwise be missed. Rapid Retracts - Allows a rapid retract rather than feeding out. Arc Fit - Convert where possible, linear moves to arcs. Draft angle - This option will draft the cutting layers outwards from bottom up. The aim is to have a conical opening for the roughed pocket. Useful for tapered cutters. Filtering - Filter out very small toolpaths that increase cycle time. Remove Corner Pegs - When Offset strategy is used allows for greater step over values, by picking out internal corner. Adaptive Feedrate - Automatically adapts the feedrate depending on the tool engagement volume in the material. New features added to Z Level 3D Finishing Rest Finishing - Machine remaining material left by a previous larger tool. Lead In-Out - Defines the lead-in/out motion. Following types are available: Tangential, Reverse Tangential Arc, Orthogonal Arc, Reverse Vertical Tangential Arc, Horizontal Tangential Arc, Tangential Line, Reverse Tangential line and Orthogonal line. Material Stock Containment - Use the material stock to contain the toolpaths. Gouge Check - Specify Models to be avoided. Silhouette Containment - Limits the machining area by the silhouette of the machining surfaces. Adaptive Depth of Cut - Additional passes are added to shallow areas in order to keep a more constant surface finish Rapid Retracts - Allows a rapid retract rather than feeding out. Round corners - Enables to filleting of inner corners with the specified radius. New features added to Parallel 3D Finishing Rest Finishing - Machine remaining material left by a previous larger tool. Lead In-Out - Defines the lead-in/out motion. Following types are available: Tangential, Reverse Tangential Arc, Orthogonal Arc, Reverse Vertical Tangential Arc, Horizontal Tangential Arc, Tangential Line, Reverse Tangential line and Orthogonal line. Material Stock Containment - Use the material stock to contain the toolpaths. Gouge Check - Specify Models to be avoided. Silhouette Containment - Limits the machining area by the silhouette of the machining surfaces. Adaptive Stepover - Creates additional parallel cuts on the steep areas. Rapid Retracts - Allows a rapid retract rather than feeding out. Round corners - Enables to filleting of inner corners with the specified radius. Added new option to shown Contours and Models while simulating, before these were hidden during simulation Added new option to shown Contours and Models while simulating, before these were hidden during simulation Removed requirement for there to be Material Stock during simulation, if no Material Stock is present Toolpath animation is still possible 3D Machining Strategies - Containment Contours and be specified to work with Inside or Outside containment with an optional additional offset value. Models can now be exploded such that each face is a Model. New option in Text mode - Text can follow selected Contour, from a basic Circle to any shape. New 'Propagate' option on 'Confirm Tool Selection' message - Gives the ability to change the tool used by all operations that share the same tool.
2.1.0 - SharpCam 3D	New Tool feature: Units. Allows a tools linear data - diameter and length etc, to be defined in one unit and used to machine a part that is set to the opposite units. For example you can define all your tools in Inch and if you machine a Metric part the tool data is internally converted to metric, this saves having to create two sets of tools if you cut Inch and Metric parts. New command added: 'Edit Contour Element' to the Modify menu and toolbar. Allows existing Contour Element's to be edited. German tranalation available.
2.0.1 - SharpCam 3D	Fixed problem opening Inch STEP and IGES files. Files were being converted to metric Fixed problem being unable to save SharpCam Version 1.5 files which contained Material Stock. Improved contour extraction from model edges..
