What is found in all disciplines of drawing?
The concepts, projection methods and drawing techniques that are used when solving geometric solid problems.
What approach should you follow with any geometric solid problem?
It is advisable to follow a methodical approach when solving it.
What are the first 3 steps for solving a solid geometry problem?
- Read the question carefully.
- Understand what you have to do.
- Plan your answer.
What do you do to solve a solid geometry problem after you have planned your answer?
- Determine the positioning of the base and draw it.
- Number the corners of the base before projecting.
- Project the complete view.
What do you do to solve a solid geometry problem after you have projected the complete view?
- Draw the complete view before projecting a cutting plane onto it.
- Draw the outline of the cut surface first, and then add what is left after truncating the piece that hides the cut surface from view.
When does a solid geometry problem seem far more complex than it actually is?
When they give you a combination of two or more right regular geometrical solids to draw.
What is the problem with giving two or more right regular geometrical solids to draw?
The confusion arises from the complexity of the combination of the solids and the many projection lines generated by the extra information that has to be drawn.
What is the trick to easily projecting a combination of right regular geometric solids?
You have to develop a reliable method of reducing the question to its simplest form.
What is the first method for simplifying a combination of right regular geometric solids?
Add numbers to the corners of one solid and letters to the corners of the other solid then proceed with your drawing.
What is the second method for simplifying a combination of right regular geometric solids?
Project one of the solids completely, as though there were only one, and then project the other solid.
Should you stick with a single method for simplifying a combination of right regular geometric solids?
No. A combination of both methods is usually recommended for the best results.
