The Purpose of Drawing Tools Help make an idea a reality Allow the designer to Present their idea to a client Give a visual representation of their idea Give the landscape contractor the details necessary to make an idea a reality

The Tools of Landscape Design and how they work

T-Square Long straight-edge Used to draw straight parallel horizontal or vertical lines Important to keep the t-square flush with the drawing board Common uses Representation of property lines, roads, drives, fences, utility lines and for adding boarders Also used to support other tools such as triangles and lettering templates

Drawing Pencil Link between the designers mind and the paper Range from inexpensive wood pencils to the more costly, but longer lasting lead holders

Drawing Leads H Harder leads The higher the number the harder the lead Lighter lines Longer lasting B Softer leads The higher the number the softer the lead Darker lines Easily smudges and requires more sharpening No rules exsist but most landscape designers work with 2H or 3H lead

Lettering Guides or Templates Used to create a stenciled lettering style Template must be matched to the width of the lead tip being used Results in lettering that is stiff and mechanical Used in combination with the T-Square

Ames Lettering Guide Plastic device used with a t-square to produce guidelines for hand lettering Can be set to create lines in varying numbers and varying width that can be replicated endlessly without additional measurement Also has straight edges that allow it to be used in the actual creation of lettering too.

Triangles Have either 30-60-90 or 45-45-90 degree combinations Used by themselves as straight edges or in combination with the T-square to create lines of consistent angles of 30, 45, 60 or 90 degrees

Compass Used for creating circles, the basis for many landscape features such as plants, patios, pools and lawn areas Remember when drawing circles that the distance between the two legs of the compass should be half the desired diameter of the circle Ex: You desire a circle with a 4” diameter, so the compass legs should have a spacing of 2”

Curves Hard plastic or flexible plastic supports for curvilinear lines French Curves Hard plastic & available in assorted shapes Flexible Curves Flexible plastic that allows limitless support for the designer as it can twisted into practically any shape

Scale Used to represent actual dimensions in a reduced size Triangular in shape that provides 6 edges 2 common types Engineers Scale Architect’s Scale

Engineer’s Scale Divides the inch into various multiples of 10 Permits dimensions to be read as whole numbers and decimal portions

Architect’s Scale Divides the inch in a number of ways that permit dimensions to be represented as feet and inches

Line Length to Represent 100 Feet Reading Scales Line Length to Represent 100 Feet Scale of the Plan Architects Scale Engineer’s Scale 1”=10’ 10 inches 1”=20’ 5 inches 1”=40’ 2 ½ inches 1/16”=1’ 6-1/4 inches 1/8”=1’ 12-1/2 inches 1/4”=1’ 25 inches See figure 1-17 p. 10 in the text.

Templates Available in a variety of styles and sizes Circle Irrigation Tree and Shrub

Erasers Plastic erasers Kneaded erasers Special purpose erasers Used the most Kneaded erasers Used for lightening lines Special purpose erasers Used for the removal of ink or colored marker but do not work as well as claimed Liquid erasers Used for removing old, dried ink lines or those created by copy machines

Erasure Shield Helpful when erasing soft B leads or small portions of a line
