+```python
+from Pynite import FEModel3D
+import pynite_tools.visualize as pv
+
+model = FEModel3D(...) # Build your model
+
+# pv.plot_model is the "express" function
+pv.plot_model(model, combo_name="LC1")

+# pv.Renderer is a class that gives you detailed control of the plot
+model_renderer = pv.Renderer(model, combo_name="LC1")

+## For example...
+model_renderer.annotation_size = 5
+model_renderer.window_width = 1200
+model_renderer.window_height = 1000
+
+## Now render the model
