Sketch Activity 3 Questions

In activity 1, step 2, the directions have you roughly draw out the basic shape before adding any constraints or dimensions. Why?

In activity 1, step 3, you are asked to add a perpendicular constraint to the design. What does perpendicular mean in this situation?

In activity 1, step 3c, you are asked to add an equal constraint to two pairs of lines. Please explain what the equal constraint will do to these pairs of lines?

In activity 1, step 4a, you were asked to place a 500 mm dimension on the bottom line. How will that dimension effect the line circled in red? Why is the line circled in red effected by the first line at all?

In activity 2, step 1, you are asked to convert lines to construction lines. Explain what construction lines are and how they are being used in this situation.

When looking for the midpoint of a line, what shape glyph should you be looking for?

• Triangle

• Horizontal Line

• Vertical Line

• Two horizontal lines

• T shaped lines

In activity 2, step 2, you were asked to create fillets in the intersections. The note at the bottom of 2c mentions that adding fillets in a sketch is not the best option. Explain why.

If I wanted to create multiple fillets with different radius values I would need to ...

• Use the fillet command for each new radius value

• Bundle all the different radius values in to one command

• Pick the most important values and work backwards

In activity 3, step 2, you place equal constraints on the 5 circles after dimensioning the first circle to 50 mm. What is the diameter of the 5 other circles after you placed the equal constraint on them?

• 50

• 25

• 45

• How am I suppose to know?

In activity 3, step 2, you place equal constraints on the 5 circles after dimensioning the first circle to 50 mm. If we change the dimension of the first circle from 50 to 70 mm, will the other five circles change as well? (Test this out if you do not know.)
