A quick note on the What's New for Pen Sketch. On page 176 we describe being able to add dimensions by using the pen to hand write the dimension digits in the graphics area with an entity selected. This function is not in Beta 1, but it should be available in Beta 2 for testing.
I will write a blog post on the new stuff you can do in Pen Sketch soon. Stay tuned.
