Traditionally, the average turn length and number of turns of a conventional magnet coil is roughly estimated during the magnet physical design. Based on these estimates, the resistance, water flow and overall dimensions of the coil are calculated. But for a complex coil shape, it is very difficult to determine how many turns a coil will have and, more importantly, specifically how it will be wound. In many cases, an engineer will use a scale model to do a winding trial, but the coil parameters, such as the conductor length and overall coil dimensions, still cannot be precisely determined. 3D CAD modeling was used for the design of the Advanced Light Source (ALS) combined function sextupole magnet coils. The winding procedures for 11 types of coils were all determined by the models. The resistances and water flow requirements of those coils were calculated from the 3D models, and those parameters were used as criteria for production quality control thereafter. This paper will introduce some basic modeling techniques that are useful for 3D CAD modeling of magnet coils. The coil data comparison between 3D model and true built coils will be introduced as well.

Fabrication of the cold mass of the first coupling coil magnet has been completed in China and the cold mass arrived at LBNL in late 2011. Preparations for testing the cold mass are currently under way at Fermilab. Plans for the RFCC module assembly and integration are being developed and will be described.
