rotation angle of the arrowhead block in leader
rotation angle of the arrowhead block in leader
as for leader,
we can get the arrowhead block by oddbleader::dimldrblk(),
get the scalefactors of the arrowhead block by oddbleader::dimasz(),
get the insertion point of the arrowhead block by oddbleader::vertexat(0),
but how can we get the rotation angle of the arrowhead block?
or, we should calculate the rotation angle by ourselves?
thank you very much!
hello yeyunxiaopan,
try to use next code:
code:

odgevector3d vec = oddbleader::vertexat(0) - oddbleader::vertexat(0);
double arrowheadrot;
odgevector3d vnormal = oddbleader::normal();
if ( vnormal != odgevector3d::kzaxis )
{
arrowheadrot = odgematrix3d:lanetoworld(vnormal).getcsxaxis().angleto(vec, vnormal);
} else
{
arrowheadrot = odgevector3d::kxaxis.angleto(vec, vnormal);
}
best regards,
sergey z.
thanks a lot!
i think that maybe there should be a little modification to the codes as follows
odgevector3d vec = oddbleader::vertexat(0) - oddbleader::vertexat(1);

yes of course. i am sorry. it is my mistake.-(
