3D view being cut off.

[Anonymous]

I have been working on a building model for some time now and started expanding the site work today. It's all simple slabs representing lawn, parking spaces and a road. When I go to 3D view one edge of the site is inexplicably cut off. It ends as if it is cut with a section tool or elevation tool (it's not). Scrolling out to expand the view doesn't change anything. The end of the model is simply sliced off and I can't find a way to expand it to include all of the model. In plan view nothing is amiss. It all shows normally.
Thank you all for any suggestions.

I find 22 faster than 21, so wonder if the issue isn't related to your old hardware (e.g., older graphics adapter) or some software conflict. Maybe give tech support a call for any ideas that they might have?

I'm not sure your reply was meant for me. I'm on V19 and I wouldn't characterize this issue as a hardware or software conflict. At least I don't think so. It's as if there is an edge or limit to the model which I'm pretty sure doesn't exist in Archicad.
It's sort of like the community from the old tv series called 'The Prisoner'.

There was a cutting plane I must have inadvertently turned on. I've never used them before. And am surprised that there is indicator for them.
