Matching
Write the number of the correct answer on the line.
a. Isoplane switch ______ |
1. Ellipse |
b. Isocircle ______ |
2. 30°, 30° |
c. Right isoplane text ______ |
3. 30°, –30° |
d. Top isoplane text ______ |
4. <F5> |
e. Default view ______ |
5. Current display |
True or False
Circle the correct answer.
True or False: Isometric drawings are two-dimensional.
True or False: Isometric drawings show no true distances.
True or False: To draw an isometric circle, it is necessary to specify a center point.
True or False: To switch isoplanes, you must open the Drafting Settings dialog box.
True or False: Drawing isocircles is the same as drawing ellipses in orthographic views.
Questions
What are the angles of the crosshairs and grid lines in an isometric grid?
What are the names for the isometric planes in AutoCAD?
What is an isocircle? Why are isocircles drawn with the ELLIPSE command?
How many different isocircles can you draw with the same radius and the same center point?
What rotation angle and oblique angle are used to align text with each of the three isoplanes?
Drawing Problems
Using the isometric grid, draw a 4 × 4 square in the right isoplane.
Copy the square back 4.00 units along the left isoplane.
Connect the corners of the two squares to form an isometric cube. Erase any lines that would be hidden in this object.
Use text rotation and obliquing to draw the word Top in the top plane of the cube so that the text is centered on the face and aligned with its edges. The text should be 0.5-unit high.
In a similar manner, draw the word Left at the center of the left side and the word Right at the center of the right side. All text should align with the face on which it is located.
