No, the ArchiCAD+ forum wasn't the right place to ask about Artlantis... I've moved this to the Rendering forum.
Parallel views are easily set up in Artlantis if you follow the steps in the help file to use the 2D window to set up the bounding 'box' ... you need to shrink the box to crop just the part of the building you want... make sure that the viewpoint is in front of the building and the back cutting plane is behind the building, or where you want it.
Consider visiting the Artlantis forums here:
