This is a typical cable railing style used for residential or commercial projects. This style is composed of a harwood top rail comprised of two pieces, 2x2 black metal posts, and horizontal steel cables. The top rail is 36above floor level. The posts are spaced a maximum of 8' on center. The cables are spaced 4 on center. This railing was created in AutoCad Architecture 2017 as a railing style. As such, you have complete control over many customizable settings with the style editor. The railing object was then imported into 3ds Max 2017 and the previews were rendered using V-Ray Next 2.1. In AutoCad, the rail style does not have any materials assigned. In 3ds Max, the materials and textures that you see in the previews are included in the .zip file. We use these railings for our 3D models of residential and commercial projects built in AutoCad and imported into 3ds Max.
