I need an .STL file and have not used AutoCAD before. In the interest of not chasing around in circles, I could use some info beforehand.
Should 3D objects that will be interacting in Boolean processes ( addition, subtraction, intersection ) be constructed in the same layer? Is layering even applicable to 3D modelling?
Can those objects be defined with their co-ordinates relative to each other, according to their positioning in the Boolean processes, or must they be constructed with the 0,0,0 origin as part of each object?
Can scaling and object co-ordinates be defined with integers and then converted en masse to fractions or other units later? ( e.g. tenths, millimeters, cubits etc. )
