Hi,
SR3DBuilder primary purpose is to project your model and test its functionality without the need of building it.
You can also revise the order in which parts are added to your model using the Instruction Miner tool (there is still not a guide about it), save your model and load it with step by step pause creating a sort of Visual Instructions.
If you want to create printable instruction is better to refer to other specialized software like lPub.
I never used it, but you can easily find some tutorial on the net.
