C3D 2015
The first time i make a surface I have no problems with contours or their labels. They are visible and they print fine.
But when I have to add additional topo info and edit the surface to include the new info.
The contours and labels sometimes won't display at all even with everything thawed & turned on. Sometimes they display but won't print. Sometime they wont display but will print (yeah thats a weird one) Even after a REGENALL
The weird thing is they do show up & print fine in the site plan dwg. as normal.
Any suggestions on where to look for solutions.
Thanks
