WD -the aftermath

Just like the hitch hikers guide.... the first rule is 'dont panic'.

To those students that received a 'NN' grade most were in the 4.5 to 4.8 range.
Students with NN results lower than that were essentially for incomplete submissions.
The highest mark was a 9 the average mark was a 5.6.
Without getting all techie/ mathematical statistical; the range looked only a little skewed toward the NN side, but this was also due to several non-submissions of the project.

(20% is a hill of...beans)

It is only weighted 20%, so it is not game over by a long shot.
Revit levels the playing field, and homogenises the output a little, so it is less likely to cause data errors (missing elements).

So complete the model in 3D as much as you can, then move into 2D line work. This project is not due in until 2nd semester, so there is oodles of time to learn the program.
(the focus of your time at the moment should be DESIGN!)
