WOODWORKING
- Sections: A section is a cut away of the object. In other words, it is what you would see on the inside if
the object were to be cut open. This allows the builder to see how the object is constructed, what type of
cuts to make (dado, rabbet, dowel, etc.), where joints are located, and how the project is assembled. - Details: Detail drawings are enlarged drawings of complex joints and/or assemblies, which make it
easier to understand exactly how something is to be constructed. These might include how door hinges
are attached, the size and location of a mortise and tendon, or the shape of a beveled/contoured edge. - Dimensions: All measurements for cutting and constructing your project must be included in the
drawing. Your dimensions not only communicate the height, depth, and length of an object, but also
the location of each attached piece of lumber, special cut-outs, hole location, and hole size. - Special notes: In some cases, special notes may be required, such as the types of material used or the
name of hardware being used. These are indicated on the drawing with an arrow beginning either at
the first or last word of your note and pointing to the location referenced.
Line types and drafting symbols
When drawing a set of working plans, it is important to use correct lines and drafting symbols. These will help
you read your plans easily and understand the instructions clearly. Below are basic drawing standards used
throughout the world.
