it is a heavy line that defines the shape and size of an object in a blueprint
A section line in drafting is a symbolic representation used to indicate where a cut or section through an object has been made to reveal its internal features. It typically appears as a dashed or solid line on a drawing, often labeled with a reference to the corresponding sectional view. Section lines help convey details that are not visible in external views, providing a clearer understanding of the object's structure and design.
In technical drawing and drafting, the object line (or visible line) has precedence over all other types of lines. Object lines are the thickest and darkest lines used to represent the edges of an object, clearly defining its shape. Other lines, such as hidden lines, center lines, and dimension lines, are used to convey additional information but are less prominent than object lines.

Object Line
An object has line symmetry if it can be divided into two identical halves that are mirror images of each other along a specific line, known as the line of symmetry. To check for line symmetry, you can fold the object along the line; if the two halves match perfectly, the object is symmetric. Common examples include shapes like circles, squares, and hearts. If no line can be drawn where the halves are identical, the object lacks line symmetry.
A short break line in drafting is made by using a thick, solid, wavy freehand line. It is used to break up an object.
A drafting line used to outline a shape or define dimensions of an object is called a "construction line" or "constructional line". These lines help in creating accurate and precise drawings by serving as a guide for the final drawing and ensuring proper alignment and proportions.

what a center line is, is a line in the center used for drafting thanks for the question i really had a good time looking up for you.
The spacing from the object line to the first dimension line is typically set to ensure clarity and readability in technical drawings. Standard practice often recommends a gap of about 3-5 mm (1/8 to 1/4 inch), but this can vary depending on the specific drafting standards being followed, such as ANSI or ISO guidelines. It's important to maintain consistent spacing throughout the drawing for uniformity. Always refer to the relevant drafting standards for precise requirements.
The "Alphabet of Lines" refers to the different styles of lines used in drafting such as to show different features about an object that is drawn: hidden. construction, cutting-plane, visible (object), dimension, extention, phantom, center, section, and border.AnswerIn Drafting, or Computer Aided Drafting (CAD) -- the alphabet of lines are the different lines that draftsmen, architects, engineers, et al use when constructing a drawing. For example, a thick solid line is called an object line and represents the outline of a part on a drawing. A dash line represents an edge that is not visible in a particular view, hence it is called a hidden line.Other common lines used in drafting include dimension lines, extension lines, construction lines, border lines, center lines, among many others depending on the type of drawing.
A border line for drafting is a firm line defining the edge or limit of a drawing or document. It helps to visually separate the content of the drawing from excess space and ensures that the drawing is contained within a specific area.
