Yup - to create a construction line through a point, when you are in a drawing command move your mouse to that point and then click and hold down on the point and drag away - that "hold and drag" type method will pull out a construction line from any spot.

Construction lines are covered in part of the tutorials here: http://moi3d.com/1.0/docs/tutorials.htm

and there is also a lot of information here: http://moi3d.com/1.0/docs/moi_command_reference10.htm#constructionlines

Hope this helps!
