Extra processing flows - Contour extraction

The SOLIDOS modeler can be used to model one or more external contours that will be used to cut out a surface, producing this effect:

Note the waterfalls on the left. They are not hidden by the surface (created with the command SEXTRACTBOUNDARIES ). p>

To use this extra flow, follow the steps:

1. Choose a point in the flowchart to stop and insert an IF
   Tip: choose a point where you already have all the information needed to create the external contour, even if you don't model the device itself
2. Create a flowchart to draw an external contour. The most "difficult" ones are for those longitudinal devices:
   
   
3. An example of a point device:
   
   Note that in this device, the contour will be the external projection of the walls, so I chose a point on the flowchart where I already have the points calculated:
   
   

Important notes:

1. The flowchart that performs the extraction of the external contour is only called by the command SEXTRACTBOUNDARIES
2. Any changes to the device properties while executing the SEXTRACTBOUNDARIES command will be ignored
3. Any solids or blocks exposed during execution of the SEXTRACTBOUNDARIES command will be ignored
4. If you want the contour to be visible in Model Space, you must create a flowchart that exposes this contour, in the same way you do to expose the device's solids:
   
   
   Compare this flowchart with the previous one. It does not check whether the flow is to calculate the contour or to model the solids.
5. The process of modeling external contours can be time-consuming for complex contours, so avoid the situation above, always preferring to separate the device construction flows while creating the external contour
