I am a newbie to this software and am in an evaluation phase before I buy.
Not sure how many people out there are using this software as an artistic aid.
Seems that it would be great to visualise projects in an interactive way before construction.
Problem I am having is that I am trying to join objects. Seems that this is possible with the 'snap objects by verticies' but what if I want to extend the object, a surface of it until it intercepts another object.
I would attach the file to this posting if I knew how to and supply the file I am working on at the moment and it is obvious where I am stuck.

Temporarily frustrated,
