3D Toolpath Files
Files from Vectric's Cut3D, PhotoVCarve and Design and Make Machinist that include 3D toolpaths can be imported into Cut2D Pro using the main menu command: File ► Import ► PhotoVCarve, Machinist or Cut3D Toolpaths.
The 3D file must first be scaled to the required size before toolpaths are calculated, and then the complete file saved ready for importing into Cut2D Pro. These files can only be moved and positioned inside Cut2D Pro but cannot be scaled.
A Grayscale thumbnail of the 3D job is drawn in the 2D View with the X0 Y0 origin at the position it was set in Cut3D, PhotoVCarve or Design and Make Machinist. The associated toolpath(s) are also drawn in the 3D window and the names appear in the Toolpath list.
Positioning
To move the 3D design toolpaths:
Open the 2D Window, Click the Left mouse Twice on grayscale image (turns light Blue to indicate it's selected) Drag to the required position Or use the Move or Alignment tools for accurate positioning.The toolpath(s) are automatically moved in the 3D window to the same XY position as the image.
Origin for the 3D data at X0 Y0
Grayscale image moved to middle of job
Toolpaths for the example above have been calculated with the X0 Y0 in the middle of the 3D design. When imported into Cut2D the data is automatically positioned using the same coordinates, which places three quarters of the design off the job. In the second image the grayscale image has been moved to the middle of the job.
The 2D mirror and rotate drawing tools can also be used to edit the 3D data set.
3D toolpaths can also be copied using the 
Duplicate Toolpath command on the Toolpaths Tab making it very easy to use multiple elements from a single design on a job.
The thumbnail preview is also copied for each toolpath, making it very easy to position additional copies of a 3D toolpath.
For example, a single design can be copied and mirrored to create Left and Right versions of a 3D design or to place multiple copies of a decorative design in the corners of a cabinet door panel as shown below.
The 4 corner roses are all copied from a single file
Toolpaths for the 3D elements can be previewed along with the conventional Profile, Pocketing and Drilling toolpaths, and everything will be saved ready for machining.
A good example of where this functionality might be used in conjunction with PhotoVCarve is for making personalized picture frames that include the PhotoVCarve grooves plus descriptive engraved text and a decorative Profiled or Beveled border. As shown below:

text and decorative border

Options
Imported toolpaths can also be edited to position them inside the material or to change the cutting parameters - speeds and feed rates can be changed.
Click the Edit toolpath icon or Double click on the toolpath name to open the edit form.
For example, after machining a half-inch deep pocket a PhotoVCarve design can then be edited to have a Start Depth = 0.5 inches and this will carve the photograph onto the base of the pocket surface.
