Remove Facets from Fixing

Fixing Finished Facets

Sometimes it is necessary to fix facets that are practically finished considering their minor deviations from the initial plan and continue changing the plan for the remaining facets only. The system provides this ability.

Image Added

The "Threshold" parameters define which facets should be fixed. The facets of the SR start model and initial scan are compared. The facets will be fixed during SR (both conditions should be met):

• FixSomeThresholdSlope (°) if an angle (slope) between the facet normals is less than the specified value.
• FixSomeThresholdDistance (µm) if the distance from the plane to "0" difference is less than the specified value.

The other 2 parameters are responsible for enabling-disabling fixing of facets filtered by thresholds:

• FixSomeFlagOnlyNormal the system tries to find solution where only normal is fixed if such solution is also not found, the usual Smart Recut without fixing facets is run.
• FixSomeFlagComplete the system tries to completely fix the facets (all parameters of the facet are tried to be fixed) - if the corresponding solution is found, the facet is fixed. If such solution is not found, the system tries to find solution where only normal is fixed (the FixSomeFlagOnlyNormal should be set to "1") - if such solution is also not found, the usual Smart Recut without fixing facets is run.

"0" is turned off, "1" (or any value different from "0") turned on. You can try FixSomeFlagOnlyNormal without FixSomeFlagComplete to make Smart Recut faster.

Interaction of Different Fixing Options

How different fix options interact with each other and with the Allow Girdle Extra Facets option:

• If you select the Allow Girdle Extra Facets option, the Fix Girdle and its additions (+ Crown or + Pavilion) become unavailable, but you still can use FixSome with its thresholds.
• When you use Fix Girdle and/or its additions (+ Crown or + Pavilion), for the areas remaining unfixed you may use or not use FixSome.
• When you exclude manually some facets from Fix Girdle and its additions, the excluded ones become part of an unfixed area for which you may use or not use FixSome.
• You may use FixSome standalone.
