Hi Tamsin, I created light positions using this technique, but when I add lights to the position, they snap to the 0 level pipe, not to the one in the air.... Any suggestions? It's a bummer to have to move all the lights from the ground to the pipe.
"It sounds like you may have 3D only elements in your truss. Objects within VW are usually hybrid, meaning they have a 2D and a 3D representation sandwiched into the same object. You need to draw a 2D representation as well as the 3D version, select both and create a symbol (Modify > Create Symbol). You can then nominate the insertion point as you wish, snap together the number of lengths you want, select them all and use Modify > Group. When they are grouped, you can convert them to a Light Position. in Top/Plan, the 2D part of the symbol will be displayed. In 3D, the 3D element will be displayed.
Hope that helps "
