Table of Contents


HPOxygen HP Carbon is designed to work with multiple models simultaneously in a transparent and intuitive manner. The working models are listed on the Plans & Scans panel.


The models are named automatically in a the following manner:

NameOriginPossible number of instances per project
Shadow scanModel produced by shadow scanning.At most one, since performing a new shadow scan erases the existing models.

Pavilion Reflect scan

Crown Reflect scan

Models produced by reflect scanning.

Any number.
Edited modelModel produced by manual editing.Any number.
Refined scanName used by older versions of HPOxygen instead of modern Reflect scan and Edited model.Any number.
Imported modelModel imported from an a *.oxgz file (to do so, press FileImport → Model in the top menu), or opened from a *.dmc, *.gem, or *.mmd file.Any number.
SampleModel imported as a sample (to do so, press Load Sample on the Scan & Build panel).At most one, since loading a new sample unloads the existing one.
<number>Recut solution.Any number.


The list contains the following data for each model:


-Checkbox A checkbox indicating whether the solution is selected (see Selecting below).
#Model Name/Solution NumberModel name (assigned automatically); in case of recut solutions, just the number.
-Label ColorColor label. Applicable to solutions only.
-Clarity Status

Clarity status marker. Possible values: - not set (default state), - Draft, - Precise.

PricePriceEstimated price according to the price list. Applicable to solutions only.
CuttingCuttingCutting type. Applicable to solutions only.
MassMassMass of the stone.
YieldYieldYield (percentage of mass of the original stone retained in the recut). Applicable to solutions only.
ClarityClarityEstimated clarity grade. Applicable to solutions only.
ColDiamond color (DZ)Estimated color. See DZ Color Estimate for more details.
Sym-OOptical SymmetryEstimated optical symmetry. When turned on, requires the recalculation of optical symmetry for all models upon opening a file, which is a computationally demanding procedure and may cause perceptible delay. By default, this option is off, and the column is displayed empty.
GrGrade by GIA FacetwareEstimated overall grade.
CutCut Grade by GIA FacetwareEstimated cut grade.
SymSymmetry Grade by GIA FacetwareEstimated symmetry grade.


The Scan & Build panel also contains the list of working models with the same basic functionality.  Note that it contains just the scans, and not the recut solutions. The columns specific to solutions are also hidden.




One of the scans is considered the Main Scan. Its name in the list is emphasized with bold font and (only when selected together with another model) green background.


A sample is a standard model to refine your stone against (see Shadow Scan). It can be loaded from a *.dmc file on the Scan & Build panel. Once loaded, it remains in your list of models under the name Sample.

Selecting models

Any model can be selected for viewing. Moreover, any combination of models may be selected simultaneously and viewed together in different colors (assigned automatically). For more details on the selection interface, see below.


Any model except the Main Scan (see above) can be deleted from the list by pressing Delete on the keyboard or selecting Delete model in the context menu.




Right-clicking on a model in the list causes the context menu to appear.


Note also that the Main Scan can not be deleted even when deleting multiple selections in which it is included.




The top part of the Plans & Scans panel contains two buttons that act on the selected model(s):


Note that the latter button is multi-optional. The dropdown list to the right provides a selection of options: Standard ReportPolish ReportCustom Report, and Print Label. Once selected, the option persists until the program is closed or a new model is opened.

Model Building Info

When a scan is selected, the Model Building Info panel is shown displayed to the right (see Model Building Info (MBI) for more details).



Scanned models prepared in the older versions of HPOxygen may lack the Model Building Info.

Comparing models

Any two models can be selected for comparison (see Comparative Report). If one recut solution is selected, it would be compared against the Main Scan (which is automatically selected as well in this case). If two solutions are selected, they would be compared against each other, even though the Main Scan is selected too.
