• Introduction and Holding the Pencil - Hooks / Set

  Today we are going to practice how to hold a pencil and how to draw a straight  line without a straight edge.  Architects, Engineers and Contractors must be able to sketch what they see and what they are going to build, EVEN if they are drawing on wood.  The written word is many times misunderstood but a simple sketch of the project will many times communicate an idea much better.   The better we sketch, the better we communicate.  Holding the pencil in a natural way is best.  Hold the pencil back from the point.  Demonstration here.  This is not brain surgery, the instructor will go over the use of words like Horizontal, Vertical, and Diagonal(45 degrees)-these lines are accomplished without the use of a straight edge --This is developed skill-   These simple lines  will become simple objects -THUS communication without the use of the written word-which is something this entire generation of Americans has lost and simply does not understand.

  • Sketching Lines PowerPoint [ Download ] Covers the purposes, techniques including size and proportion of sketching objects, the use of the standard alphabet of lines, and strokes used for sketching horizontal and vertical lines, arcs, and circles.
• Horizontal Straight Line Practice - Demo / Modeling

  The instructor demonstrates drawing freehand equally spaced horizontal lines on the board.  Students practice this at their desk.   Hold your  wrist stiff, movement comes from the shoulder.
  Fill 2  pages of practice.  To be checked by instructor walking around the room.
• Vertical and Diagonal Line Practice - Other

  Drawing at their desks, students now draw practice vertical and diagonal PARALLEL lines filling two pages.  Instructor circulates around the room--individual help.
• Straight Line Geometric Shapes - Demo / Modeling

  Students use straight line practice to form geometric shapes. Instructor demonstrates Squares, rectangles, triangles, polygons on the board, then circulate around the room.
• Circles and Arcs/Proportion - Demo / Modeling

  The teacher demonstrates using squares to help draw circles and rectangles to help draw ellipses.  Students practice at their desk.  The teacher will discuss proportion as necessary to improve what the object really is.  If I draw a TV-it should not look like a microwave!
