Foolproof method to extract component thickness

Hi All,

I want to know if there is any robust/foolproof method to extract the midsurface of components? Currently, I am using following method to extract midsurface:

set maxpoint [hm_entitymaxid points]; set surfthickval [hm_getsurfacethicknessvalues points $maxpoint]; set thicknessbefore [lindex [lindex $surfthickval 0] 1];

I have observed that for some components this code has identified wrong thickness value (I am not sure what was the reason) and for others it was correct.

Can you guys tell me which method/code you use to calculate component thickness?

Any help is much appreciated. Thank you!!
