Hi to all,

I cannot understand very well the meaning of the parameter Material condition (Least, Nominal, Most).
Which is the meaning of it? Which is the difference?



Is there any relation with the Density Level of the footprint created?
I mean, if I am creating a footprint with Most material condition should I choose the 3D Material condition as Most? 

Regards,
david

There are 3 columns of dimensional data in the Footprint Expert component family calculators. 

Nom / Min / Max and when you select a Material Condition, the 3D STEP output will use the column of data that you select. The default setting is "Nominal" material condition.

These refer to the +/- tolerance of the feature:

Least = the minimum dimension 
Nominal = the midpoint between least and most
Most = the maximum dimension

Example 1 (symmetrical tolerance):
3.57 +/-0.10
Least= 3.47
Nominal= 3.57
Most= 3.67

Example 2 (asymmetrical tolerance): 
3.67 +0.000/-0.20
Least= 3.47
Nominal= 3.57
Most= 3.67

Typically the nominal value is the stated dimension where the + and the - tolerances are equal, as in Example 1.

The Nominal density level is the most popular in the commercial industry. 

Military weapons contractors seem to use the Maximum density level for 3D models. 

Least is never used by anyone.
