Description:
|
Returns as
tm-check:tm-bad-topology would if coedge's edge is not a
TEDGE. Otherwise, checks the coedge parameter space curve to see if it strays outside the boundaries of the coedge's face's surface. The resolution used is
resabs in parameter and will pick up most significant problems. If any problems are identified, a
tm-chk-info of derived type
tcoedge-bs2-outside-sf is returned which lists (via
tm-chk-info:coedge-param) the coedge parameter where there is a problem. The coedge parameter is negated if the coedge is reversed so as to have the same sense as the edge itself. If the parameter curve is fine in this respect, an empty list is returned.
|
|
|
coedge is an argument of type
tcoedge whose parametric curve is tested for the above mentioned condition.
