I am an architect and working in 3ds Max all of my life but going to try to make couple of projects in Blender.
Main way to modelling I use is making sections with splines and exrtude them. This way gives flexibility to change configuration of windows, walls, profiles (especially in classic architecture). But splines in Blender are very weak. And Blender has not tools for outlines, splines boolean operations, even to making simply square with spline I need to make circle first and then change ponts to corners and then rotate it to 45 degrees!!!
Is there any script or plugin to work with splines like in Max or Cinema4D?
