 The objective of this example is to demonstrate how to orient beam elements in 3D space. 
 The model we'll build is a simple 3-element portal frame with wide-flange sections.

 Only certain relevant pieces of code will be shown in detail, but the full example script can
 be downloaded from the link above.
 In order to cover a wide range of cases, we'll orient the first column, element `1`, such that the strong axis of it's section bends *outside* the plane of the portal, the strong axis of the second column, element `3`, will resist bending *inside* the portal plane (See the image above).
-We'll build two variations of the model; one where the 2nd coordinate is vertical, and another
-with the 3rd coordinate vertical.
+We'll build two variations of the model; one where the 2nd coordinate \(X_2\) is vertical, and another
+with the 3rd coordinate \(X_3\) vertical.
+In both cases we begin by initializing a `Model` in `ndm=3` dimensions with `ndf=6` degrees of freedom per node:
+```python
+import xara
+model = xara.Model(ndm=3, ndf=6)
+```
+
 For the first case with \(X_2\) vertical we have:
 ```python
 model.node(1, (    0,      0, 0))
