Avoid long text paragraphs - students fail to stay focused Comments on 3.1: 1. virstem/basic-engineering-graphics/3-section-of-shapes/3-1-cross-sections#h.nrddi1sbeyxj In a video it is possible to spot a limit case, and another answer should be added: "Line" 2. virstem/basic-engineering-graphics/3-section-of-shapes/3-1-cross-sections#h.v67wus8ttzh6 In a video it is possible to spot a limit case, and another answer should be added: "Point" It would be helpful for students to specify in more detail and add the question, "what kind of pyramid is the question about?" The cross-section of the "?" pyramid would be 3. virstem/basic-engineering-graphics/3-section-of-shapes/3-1-cross-sections#h.pq6loz30riv0 Another answer should also be added here: "Point" when a plane passes through the vertex. This fact is not even mentioned in all textbooks :-( 4. virstem/basic-engineering-graphics/3-section-of-shapes/3-1-cross-sections#h.gmyvkpns3rms In answer, "cutting plane hight" one word is misspelled - it should be "height" Comments on 3.2: Drawback: What if a student accidentally misspells the "Fill in the blanks" question having the correct comprehension? 3.2.1 In all videos it is possible to spot a limit case when a section shape turns into a line! Wedge: In two answers, a word "hight" is misspelled - it should be "height" Regular square base pyramid: In a video it is possible to spot a limit case, and another answer should be added: "Point" 3.2.2. Cylinder: In an answer, a word "horisontal" is misspelled - should be "horizontal" Sphere: The question "Any cross-section of the sphere is a circle. The circle diameter consists of a section plan's ...2" is a little confusing. Maybe instead of "consists" a "depends on" was meant? Maybe "plane's" instead of "plan's"? In the answer, maybe just "angle" rather than "its angle"? Test 3.1 test In the answer a word "hight" is misspelled - it should be "height" 3.2 test "The cross section of the prism at a 90 degree (to what?) angle would be" - the reference to what 90 degrees are measured? It is difficult to imagine how "a trapezoid" can be a correct answer!? 3.3 test "The cross section of a prism at a 0 degree angle (to what?) would be" - the reference to what 90 degrees are measured? The cross section of a prism at a 90 degree angle (to what?) woud be - the reference to what 90 degrees are measured? 3.8 Regarding "The cross sections of a rotating shapes would be". Shapes typically are treated as 2D. Consider using a term "solids of revolution" which are treated as 3D Consider clarifying the question "The cross sections of the solids of revolution showed in the video above would be", otherwise, it is confusing why the answer is "rings" rather than "circles" 3.10 "For drawing of the truncated cylinder axonometrical projection is needed to use" Grammarly software suggested an improved version of this question "For drawing an axonometric projection of the truncated cylinder is needed to use" "axonometric" also in several other places Modris Dobelis Apologize for the late report - we had tight deadlines for the deliverables of our own projects

It would be useful to use more links to additional information related to e-course content.

Looks good.
