Discussion probuilder 6.0 pre-1

Im not overly loving the new setup in 6.0,. some of it, right clicking for menus, sure.. but wheres the subtract tool gone? im also struggling because im trying to trace round some existing rooms made with walls, floor, ceiling etc. so they are inverted cubes.. and i just cant, i cant cut out doors, i cant even make a polyshape because it picks random points in the distance as where i clicked, when theres a door to click round.

It just feels so much harder to use now, even bringing up the menu to select vertex, point or face isnt always simple.

 

Subtract was experimental as i recall.. I found i got it under control by running the long forgotten progrids.. Still missing subtract though.. but i did get a fair chunk done the other day using progrids, just a shame its long abandoned
