R:
BodyDiameter is the diagonal distance across the bounds of the part box. See PartDoc::GetPartBox for details.

Use ModelDocExtension::GetUserPreferenceDoubleValueRange with swImageQualityShadedDeviation to get the TessMax and TessMin.

qualityNum is the number set in ModelDoc2::SetTessellationQuality.

qualityIndex can be calculated using the first equation.

Q:
Robin,

Thanks.

How to get TessMin?

tessDeviation result which is calculated by my code is 83 according to your formula. Which unit does tessDeviation used?

If its unit is meter, it looks that tessDeviation value is too large.

My code as follows:

return tessDeviation;



Are you sure the following formula is correct? Pls check it and tell me the correct formula.

R:
The number returned by ModelDoc2.GetTessellationQuality () is the quality index. The “quality number” is the number you pass to SetTessellationQuality. The formulas are correct, but you don’t need the first formula when using ModelDoc2.GetTessellationQuality ().

Q:
Robin,

I don’t think so. I need your strict and patient guidance.

I found that quality number was equal as quality index.

long qualityNumber = 100;

dModelDoc.SetTessellationQuality(qualityNumber);

// qualityIndex is 100 in watch window

long qualityIndex = dModelDoc.GetTessellationQuality();

As view as your given formula, qualityIndex value is between TessMin and TessMax and its unit is meter.

Consider TessMax is 0.001, TessMin is 0 and qualityNum is 100, qualityIndex is 0.001.

But, as view as SW_API help doc, qualityIndex should be number, not value with unit.

R:
Sorry, I made a mistake in my last email. The number returned by GetTessellationQuality is the quality Number.



Use the qualityIndex returned by the formula to find the deviation.
