Using TD17 Deluxe, I have a 3d model of my building, and I want to add 3 layers: one to show where in the plant earplugs need to be used, and one with all the fire alarms, pull stations, etc., and one highlighting exit routes.
2 separate questions: First, the hearing conservation and exit routes can be 2d, overlaid on the top-down view of the model. Do I do this in paper, or add a layer with a visible workplane (or something like that?)
Second, each time I try to add the layer for the fire alarms & fire extinguishers, as soon as I start adding elements to the layer the model jumps back to layer 0. Is there a setting I've screwed up somewhere?
Thanks in advance for any help,
