This section describes how to generate loop drawings using an external CAD engine such as SmartSketch, AutoCAD, or MicroStation.
The CAD session is based on SmartSketch. The procedures for AutoCAD and MicroStation are very similar.
Conventional loop drawings are generated from drawing blocks on which Smart Instrumentation data is superimposed. The great advantage of this method is that from a small number of blocks, different combinations of instrument, wiring, and control panel arrangements can be obtained, and many hundreds, or thousands, of loop drawings, each with unique data, may be generated from a single pattern. Before starting the module, make sure that the following files are located in the path <Smart Instrumentation home folder>\CAD\Blocks.

The purpose of this tutorial is not to instruct you how to define blocks or cells but rather to demonstrate how to generate loop drawings using a CAD application. At this stage, we have provided the necessary blocks to use in this Tutorial.
