thanks Karl,in this case i want to create beam and bending it , i usually draw the beam profile first and then draw the arc with spline. why i'm using spline coz with spline can do the smooth 3d beam. i always using profiler to create bending beams...but there is one step again to get the beam, i should save this beams becomes the object. next i can put this object to my roof framing plan.
if you said that the complex profile can do this case please show me the way how to create it.
and thanks for the tips to not should restart the mac after install the add on.
Cheers
