I am modelling a curved runway beam using an IPE400 GENSEC beam. The beam is complete, but when I attempt to try to add the boltholes to the top flange (NCYLs) the beam dissapears. I have typed Q LIST when standing on the GENSEC to see what the GENSEC can own. The obvious choice was a TMPL, I created the template and typed Q LIST again to see what the TMPL could own, and NCYL is included. However when I create an NCYL (or even a NXTR) the beam vanishes until the NCYL and TMPL are deleted, at which point it returns. Any ideas how to attach the NCYLS to show the boltholes. (Using V12 SP 4.12)
