There is an easier way, but it isn't the right way. You can use prefabricated supports, but they look terrible, and for realistic designs they simply would not hold. You may be able to reduce the tediousness by using the Auto Support Generator (not the wooden support one included in NL), but that is not a salve for everything. Hopefully, NoLimits 2 will address this issue, but for now you will most likely have to remain steadfast with custom support building.
