Im new to Blender (and modeling), sorry if im not using the correct terminology.
Here is the render/model in question: https://www.youtube.com/watch?v=tLf0lAGD8WM
I created this hall following Ducky 3D’s https://www.youtube.com/watch?v=pwFGNNbNMvg how-to. It has a few cubes and some NurbsPath’s.
I would like to make a copy of current hall and place that copy on the end at a 45deg angle (or 90deg). Ive tried this by placing the copy at the end having the outer corners touching each other so there is no gaps, then tried to use the knife tool ( K ) and cut out the over lapping inner walls. It worked to a degree, but does not seam like the correct way to do this. Also tried to add a Boolean Modifier, but could not get that to work at all.
Any help or proper keywords i can use to search with would be great…
