A Focus on Flexibility and Ease of Use
Mastercam X3 features let you do more faster, minimizing creation and editing time.
Swept Surface Enhancements
You can now easily create swept surfaces with sharp corners in the rails. This will help users who are producing surfaces for door or window frame shapes.
Select by Depth
Focus selection to a specific Z depth or to a zone defined by minimum and maximum Z values.
General Selection – Last
It is not uncommon to perform sequential functions on geometry selected with General Selection. Now you can choose last for any entity type and your previous selection will be used.
Xform Drag – Improved Usability
You can now hold down the [Ctrl] key when placing multiple copies of the geometry without having to press [Enter] after each location to fix the live entities. 
Xform Move to Origin
Now you can move all visible geometry to the current WCS origin quickly and easily. Once the function is started, you are prompted for an AutoCursor position. Once the position is selected, all of the geometry moves to the origin relative to that position.
The Move to Origin function now also respects the 2D/3D switch. In 2D mode, the entities are shifted in XY to line up with the origin without changing the Z value. In 3D mode, the AutoCursor position selected as the new origin is moved to 0,0,0 and all other Z values of the selected entities update respectively.
Line Perpendicular
A Flip button was added to the Line Perpendicular ribbon bar makes construction easier.
Shortcut Key for Editing Text When Placing a Dimension
The new shortcut key (J as found in Adjust Text) makes editing text easier.
Solids Layout
Streamlined layout dialogs make the interface easier to use.
