i am new to blender, so I spent the weekend trying to build a simple staircase using only planes, but I am having a hard time unioning (boolean) planes. Some times i succeed, but most of the time the operation just fails and I just do not know why.
It might have to do something with keeping my objects on the same z-axis while working on the x- and y-axis especially when snapping my objects to the grid. Although I checked the global coordinates of my objects and every single vertex using the n-key.
I attached a blend file where I already selected two planes that I can not union. Maybe you can have a look at it or maybe you have any tips or know a tutorial regarding working with planes; i couldn’t find one.
I hope you get what I mean, as English is a foreign language to me it is not easy to express myself.
