Which of the following are the main types of dimensions in dimensioning? -In dimension annotation, dimensions are mainly divided into three categories: fixed dimensions, positioning dimensions, and overall dimensions. Shaped dimensions are used to determine the shape and size of geometric elements on a planar shape, such as length, diameter or radius of arcs, etc; Positioning dimensions are used to determine the relative position between geometric elements, such as the center position of an arc; The overall size represents the total length, width, and height of the combination. Linear and diameter dimensions in option B, radius and angle dimensions in option C, and linear dimensions in option D 2. What are the types of sizes available? -Baidu Knows
1. Positioning size: This size is used to identify the specific position of the part in the large structure. For example, when excavating a cylindrical hole on a rectangular prism, the distance between the center axis of the hole and the boundary of the rectangular prism is a positioning dimension. 2. Shape dimension: This type of dimension is used to determine the size of geometric elements. In the engineering structure representation on the drawing, the fixed size is used to describe the specific size of a certain shape in the engineering structure, such as the diameter of the bottom circle of a cone? -Driving
One picture to understand the size and grade of the car: What grade is your car? There are many people who are not clear about the concept of car size, such as wheelbase. Dont worry, this note is here to help you quickly understand the classification of car size levels. It only takes 10 seconds! We mainly divide them into three categories: sedans, SUV
Shape dimension answer: ACD This question examines the basic classification of dimension annotation in engineering drawings.. ==**When annotating dimensions, the size categories mainly include positioning dimensions, overall dimensions, and final dimensions. These three types of dimensions are used to determine the relative position of geometric elements, the overall size of objects, and single shape features, and are essential annotation elements in engineering drawings. ---# # # Option Analysis -==* * A. Positioning Size * *==: Correct. Used to determine geometry 5. What are the size types of combinations? What are the meanings of various sizes? _What are the size types of combinations of hundreds? What are the meanings of various sizes? Related knowledge points: The source of the test question is to analyze the size types of composite bodies, including fixed size, positioning size, and overall size. Shaped dimensions: Determine the size and dimensions of each basic element in the combination. Positioning dimensions: Determine the mutual position between each basic element in the combination and the size to determine the position of the cutting surface. Overall dimensions: Determine the total length, width, and height of the combination What are the types, sizes, and specifications of televisions? Types: divided into two categories: cathode ray tubes and flat panels. Tablets are divided into two categories: LCD and plasma. LCD background lights are divided into two categories: LCD and LED. It can also be divided into four small pitch LED large screen
