I'm trying to make a walkway with planks for a game. As part of this, I need to make a walkway with a right angle. As such, I want to make a clean line where the planks heading in different directions combine cleanly. The picture should more clearly show the problem. I've tried creating a triangle and booleaning the planks, but that ended up not working properly. I used a cut tool to cut the planks as can be seen in the image. I'm stuck on where to go from here.
I personally think the imperfections in your joined planks look good.
However for a precise approach consider the following. The Knife Tool has the option to cut in steps of 45°.
- Go into edit mode. ↹ Tab
- Use the Knife Tool K to cut a 45 degree angle by pressing C once to activate snapping duration the operation.
- Remove the vertices which are not needed. X
- Snap the cursor to the outer corner where the planks join. ⇧ ShiftS > Cursor to selected
- Select all A and duplicate the geometry ⇧ ShiftD. Let it rest in the same place. RMB
- Activate Cursor as Pivot NumpadPeriod, then rotate the duplicated geometry 90 degree around the cursor pivot. R90⏎ Enter.
- Mirror it in Y. SY-1 or ⎈ CtrlMY
- Remove the double vertices. W>R
