Thanks for the reply, I am running VW2019. I am on two Machines at work and at home, both have the same issue. both imacs. my work machine is brand new 4.2 Core i7 with 64GB memory and Radeon Pro 580 8192 MB graphics card. My home machine is a bit older (2 years) but similar specs. You are right about the figures, they are older VW figures, the issues seam to persist even without them in the model.
I am running OS10.13 at work. I've Up[dated my home Machine the Mohave.
Display Planar objects is checked. The objects are shown. the difference is, in the viewport they are shown as white, while in the design layer they are shown with their color fill. (see attached)
I have managed to work around this, but I would love some insights as to what exactly is happening.
