3. 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

4. The Tools of Landscape Design and how they work

5. 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

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

7. 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

8. 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

9. 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.

10. 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

11. 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”

12. 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

13. 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

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

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

16. Line Length to Represent 100 Feet

18. 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

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