Sketching Practice Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Sketching Practice Put your notebooks and yesterday’s work on the lab table for me to check. Cut out your isometric drawings and tape them into your notebook
Pictorial Sketches Show shape of object Show height, width, and depth Sketching Practice Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Pictorial Sketches Show shape of object Show height, width, and depth Should always be labeled!! Pictorial drawings show the shape of an object viewed by the human eye. Pictorial sketches are sketches that show height, width, and depth all in one view. Common types of pictorial drawings are isometric and perspective.

Sketching Practice Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques Perspective Perspective is a way to draw that shows a view of the object in the most realistic way. Vanishing points are used to guide the lines in the object to the horizon line or the horizontal line you see at your line of sight.
4. One-Point Perspective Sketching Practice 4. One-Point Perspective Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques All lines in the depth project to one point (the vanishing point). The location of the vanishing point is based on your line of sight. Copy this one-point perspective sketch into your notebook. Label the front, top, and right side. Vanishing Point (VP) This is an example of one point perspective. Notice that all lines in the depth project to one point, the vanishing point. The location of the vanishing point is based on your line of sight.
One-Point Perspective Sketching Practice One-Point Perspective Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques All lines in the depth project to one point (the vanishing point). The location of the vanishing point is based on your line of sight. Copy and complete this one-point perspective sketch onto your activity. Label the front, top, and right side. Vanishing Point (VP) + This is an example of one point perspective. Notice that all lines in the depth project to one point, the vanishing point. The location of the vanishing point is based on your line of sight.
5. Two-Point Perspective Sketching Practice Gateway To Technology® Unit 1 – Lesson 1.4 – Sketching and Dimensioning Techniques 5. Two-Point Perspective VP1 VP2 In two-point perspective, the width lines converge on one vanishing point (VP1), and the depth lines converge on the other vanishing point (VP2). Copy this two-point perspective onto your activity sheet. Label the top, front, and side.
