When using an stb plot table, and when the "Use 3D Model Layers" box is checked, layer properties return to default after cutting an ortho.
When the "Use 3D Model Layers" box is checked, the Linetype, Lineweight, and Plot Style assigned to the model's pipe/equipment should follow when an ortho is cut.
For example in the model I can assign a layer called "M-FUEL-JETF-PIPE-8" a 0.5mm lineweight.
Then after cutting an ortho of said model, the layer should be "Top (Plan) View-M-FUEL-JETF-PIPE-8" with a lineweight of 0.5mm.
Thanks,
