Scanning

To scan a stone:

1. Mount the stone in the scanner.
2. Start HP Oxygen.
3. Use the  mode. The left panel goes to the Scan & Build mode.

4. On the left panel, under Cutting & Method, do one of the following:

   
   

   1. select the appropriate cutting type from the predefined list

   2. select one of the previously loaded samples or load a new sample by clicking 

      

      Info
      A sample can be loaded from a file ( *.dmc,  *.mme, or  *.gem). Once loaded, it remains in your list of models (see Models management) under the Samples section.

5. Under Precision, select the desired precision.
   HPOxygen stores the most recent precision setting for each particular cutting type separately. The stored precision setting is applied automatically whenever the cutting type selection is changed. In a typical workflow, it is recommended to scan round brilliants with 400 contours and Princess cuts with 800 contours, since the latter cutting contains more facets with a nearly similar orientation which requires higher precision to resolve.

   
   
   

6. Click Shadow scan to start scanning. You may or may not be prompted to enter the Stone ID and Measured weight, depending on the settings (see Entering Stone ID and Measured Weight for more details). The following operations will proceed automatically:
   
   
   1. As the shadow scan progresses, the shadow photos of the model in different orientations are taken and displayed on the screen, together with overlaid contours and a progress bar. 
      
      
      
      
   2. After the shadow scan is completed, the model is built based on the scanned contours.

After Scanning

Alternative Building Results

For some cuttings, there are several applicable methods. If so, they all are applied and the system then automatically selects the primary one and shows its built model. The alternative models are hidden by default. Now you can view the alternative models. To do that, in the context menu of the shadow scan model, select  Show alternative shadow building results. For the displayed secondary models you can set the main one. To do so, for the displayed secondary shadow scan model, from the context menu, select Set model as best shadow result.

Post Scan Operations

Some post-scan operations may be initiated via the Scan & Build section. Switch between Basic and Advanced set of operations using the button at the bottom of the section.
