REVIT 2010 – Custom Family - Fancy Metal Railing   It's all here starting with the CADclips newly coined 4b approach to making families (see below). Become a wiz at parametric formula driven arrays using nested family components and nested parameters within a generic linear based family. Not to mention a few priceless lessons on sketch lines and reference planes. 4b – Brains, Bones, Balance and Body. This newly adopted 4b method of explaining how to successfully create REVIT content is a wonderful thing. What does it mean? Always create the parameters, reference planes and constraints (Brain, Bones) and flex those objects (Balance) before you ever create the solid geometry (Body). You will get MUCH better results if everything flexes ok BEFORE you start to create the Body and align and constrained that solid geometry to the reference planes (Bones). The tendency is to jump to the Body aspect too soon and to NOT use enough reference planes. Sketch lines LOVE reference planes and reference planes are easy to control. Most people are not aware that you can also align and constrain the end points of sketch lines and arcs to reference planes. CADclips Login required to access these lessons.
