To define key points
For Beams, you can specify wet joint key points in addition to overall cross-section boundary key points. Wet joints can apply either only to Flanges or the full depth as diaphragms, they must be specified after checking the option for Wet Joint Key Points. OpenBridge Modeler will connect the keypoints between adjacent beams to form the wet joint. All key points between the top and bottom keypoints on each side are automatically considered for forming the edges of the wet joint. Any non-linear variation between key points is ignored.
