V5 curvature analysis
V5 curvature analysis
(OP)
When analyzing a curve or surface in V5 with the curve or surface connect checker, curvature is expressed as a percentage. Does anyone know what the percentage is? Why is it a maximum of 200%? The documentation on this is not very clear.





RE: V5 curvature analysis
According to the online documentation the maximum error if you can't achieve G2 continuity is 2 and if expressed in percentage 200 %.
RE: V5 curvature analysis
curvature is normally designated as a radius length, so I don't understand the maximum error of 2 or 200%
my guess is it's a ratio between the two curvatures. If one curvature is more than twice as large (small?) as the other, than CATIA indicates a maximum (worst case) situation. But, if the curvatures are the same, then there is a ratio of 1:1 (100%).
Can any mathmaticians or surfacing experts explain how CATIA is calculating this?
RE: V5 curvature analysis
|C1-C2| / ( |C1+C2| / 2 ) no unit a ratio
When curvature have same orientation it works well, but when inverted then result is 200% no matter what. (Which i think is not good.)
