The top reason—drawing produc- tivity within a sign company is good for business. A properly drawn attach- ment detail for an electric sign creates a clear business communication tool (i.e., a drawing) for a city planner to approve, straightaway. With a properly drawn attachment detail, if a permitting employee has an issue with a drawing, it is usually one item, and they will allow you to change it and email it to them. Great! No second visit to the city permit offices. Now you're one step closer to a final payment all because of a correctly drawn attachment detail. After a sign design is approved, a sign plan (which is called many things in the sign industry) moves into another phase of the selling process, called an approved sign plan or drawing. At this point, an attachment detail and site plan should be added to a sign submittal. So, let's talk about how to properly draw attachment details for one set of front-lit channel letters. A sectional view of an attachment detail may initially be understood from an abstract point of view. At this point, we will simply generalize each of the main areas into general component sections, four to be exact. As shown with Figure 2. There are four basic areas a designer should become familiar with: The call-outs. The sign itself. The mounting surface. And finally, the power source. This abstract overview identifies and clarifies the main areas involved with the process of drawing an attachment detail. This basic outline accelerates the learning process with a designer, a sales person and a project manager. Each per- son inside a sign company needs to know how to proofread an attachment detail. 1. The call-outs (placed on the far left, because people read from left to right). 2. A custom electric sign (with iden- tifying lines, arrows or dots identifying elements of a sign based on call-outs, also called specifications). 3. The surface on which a sign will be mounted (in this case, a building fascia). 4. The power source (usually a power supply or neon transformer). This is pretty much the norm, not necessarily the standard. Call-outs are short, written descrip- tions with identification lines that point to a specific item or area within a sign. What connects a sign to a surface are called fasteners or anchors. What con- nects a power source to a sign are insu- Call-out Component Surface Component Sign Component Electrical Component Figure C Figure 1 Figure 2
