Generally the tendon profile are shown in the drawings in both plan and elevation views, therefore the tendon profile can be described using two plan curves, one in the projected plan view and the other in the projected elevation view.
In the current RM Bridge, however, user have to input the tendon profile in 3D, which is difficult if the tendon profile have curvature in both plan and elevation.
I suggest RM Bridge allow user to input the tendon profile in both plan and elevation,which is a common practice in other software, like CSIBridge, Midas Civil, Larsa 4D, etc.
Thanks for your feedback. We have planned some enhancements for the Chinese market (where this is a common practice) for autumn this year; we will see if we can do some improvements in that directions as well.
