How to check A surface quality in nx9
(OP)
I have received A surfaces and now I have to check it . how do I check tangency, curvature and draft analysis in nx9. And what does value of particular comb represent in units.





RE: How to check A surface quality in nx9
Usage of all the different commands is a tall order for a quick forum post; I suggest you have a look at the different commands available and spend some time in the NX help files to see how to use them. Post back with any specific questions you may have.

The definition of Class A is something similar to :
"I the creator guarantee that this xxx fulfills the requirements, both in quality and shape" *
To do this one needs to have control over things like degree and number of patches/ segments.
The pole structure is to some artists "the thing" since it displays the "true shape". - You cannot cheat.
To see this you can use tools like
Information- object - face,
Information - B-surface
Analysis - shape - show poles and show Knots
There are a number of other tools that can be used to evaluate the shape but I don't think that shape was the initial question.
* Note that Class A is not the same as "curvature continuous", things can be curvature continuous and still be invalid for production.
