Assemblage 0 Posted August 18, 2010 I have a hybrid symbol with all components drawn in a single class sitting in a master modelling file. This is referenced as a "whole of model" DLVP in another file, for taking views and generating SLVPs. The symbol (3D part is just a simple extrusion) is visible in wireframe and HL in the viewing file as normal, but with OpenGL and any other 'tone' render it completely disappears. All classes and layers appear to be correct. Other elements are viewing ok in the tone renders. I have no idea why Quote Share this post Link to post
