It is a good idea to have a plan before you start building. During the initial process of generating ideas and making quick tests of ideas a few notes and sketches may be all that are required. But quick notes and a few sketches do not help the team move toward consistent, strong, repeatable structures.
When designing a structure, draw enough details and views of the design so that it is clear what is being built. A structure may have a lot of symmetry and thus only a couple of views of the design will be required to describe the structure. If the design is complex then additional views of the structure may be required.
Different views that a team may wish to to draw:
- Side View – from one side of the structure – or if necessary – from all sides
- Top View – looking down on the top of the structure
- Sectional View – a view that takes a slice through a “section” of the structure
- Detail View – a larger scale drawing of a complicated construction “detail”
- Isometric View – a three dimensional view of the structure
- Exploded View – a view much like you see in some toy assembly instructions that show the individual pieces “exploded” out from each other so it is clear how they all go together
You should be able to draw most structure designs to actual size. This makes it easier to refer to when you actually start building.
Assign numbers or labels to each structure design so that it is easy to refer to them later on.
Keep all of your designs in a notebook. You may want to augment the designs with digital photos of the completed structures.
Teaching drafting skills is beyond the scope of this website but following is a list of drafting tools and equipment a team may want to use as they begin to draw their designs.

The team may want to learn to use CAD software to draw their designs. CAD software can take a long time to learn to use. Check the links page for a link to a site that provides links to free CAD software.
Drafting Hints:
- Tape your paper down so that it can’t move
- Keep a sharp pencil
- Be as neat and precise as possible
- If you are using a CAD program consider turning on the “snap to grid” feature and set the grid size that is appropriate for the structure you are designing.
A drafting table makes it easy to draw consistently square lines. An alternative to a drafting table is to use a smooth square surface. I use glass samples (see discussion on building surfaces). Another alternative is to get a 2′ x 2′ piece of Medium Density Fiberboard (MDF) from a home improvement center and use this as your drafting surface.
A good thing to know
Many times while designing you may find the need to divide a length into something that is not easily measured on a ruler. For instance you may have an eight inch column that you want to divide into three equal pieces. Even if you do the math you cannot find the calculated measurements on your ruler. Here is an easy way to divide a line into equal sections no mater what its length. Take the example given of dividing an eight inch column into three equal sections. That means each section is 2 and 2/3 inches long – something you can’t find on your ruler. Here is an easy way to divide a length into any number of sections. Click Images for larger picture.
This same concept can be applied to dividing any line length into any number of equal sections.
