Fixtures with Asymmetric Beams Render Round - Electronic Theatre Controls Inc

Actually, in Augment3d you can set any beam angle you'd like up to 179 degrees (but not 180 Deg.).  Any fixture set that wide doesn't appear in the visualization to output much light though.

There is a Cyc in the stock Library though it won't look much different than what you have now.  It is in Venues. Find Theatre in there, expand it and you'll see it.

Correction, find Proscenium under Venues, Theatre is inside that.  Drag Theatre into your model and expand it.  Cyc is inside.  You can delete the other parts of Theatre (or make them invisible) if you don't need them.

Got it. Thanks so much! 

Better than the 10 degree spot. Thanks!
