After using the flow command, the flange is at an angle to the beam web (non 90 deg.) for oblique beams at an angle to the x-axis. However, the other beams have a good flange (90 deg.) because the beams are located along the x-axis and y-axis. How can be flange position at 90 deg. to web made for oblique beams? Thanks.
This only seems to work when the curves are parallel to a normal plane.
The command is basically missing a direction input.
So either you run the operation parallel to XZ or use sporph which flows from one surface to another. For the brep to flow nicely, you need to reparametrize the input curves
