hey guys, i am planning on soon to make a front bumper for my truck kinda like chris's(elementsenjoi) and just was curious if any body has like plans or diagram with specifications on building a bumper. just a helping type thing to help me build it and get the corect specs
here is a pic of what i am in love with and want to build something like it

 

also i have autocad but its like 10 years old but it does have the 3D setting so i thought of doing a thing on that but i am not sure how to make a bumper on there. i havent ever tryed the 3D so maybe its easy but if someone could help me with that to that would be sweet
