I am using Blender to make models for 3D printing. I always export my .blend files to .stl files and import into MakerBot.
Lets say I'm making a model with two cubes that I want to glue together with a boolean "union" operation. A very common pattern I've found is that I want to save my blender file with the two cubes separate, but every time I want to make an .stl file, I need to first apply the boolean operation, export as .stl, then close blender without saving.
Is there a way for me to export the .stl file as if I've applied the boolean operation, but keep the .blend file with the operation undone? thanks.
