Hi Will,
Currently, there is a basic tutorial on detailing. It can be found here:
http://www2.spaceclaim.com/stream/video.aspx?v=drawing_intro.flv
Also,to drop trailing zeros in dimensions, this can be done by selecting the dimension and in properties>precision, you will be able to set the number of decimal places you desire. All the other options such as units and annotations can be set under SpaceClaim Options > Detailing.
Hope this helps
Best,
Sasi
