During the first part of the production process, the steel frame is not important and often obstructs my view, so I like to hide it or put in a different layer. But inevitably by working with the model, scaling, cutting, strechting… the model and the frame lose position relative to eachother after a while and I do not notice it because the frame is hidden.
In a mildly similar scenario, but with bolts etc rather than your frame, I found that by putting the items on their own layer, making the layer colour quite transparent and locking the layer so I didn’t snap to items on it, meant that I could work in Shaded Mode with the ghostly presence of the items as an aide memoire.
