What is sectional plane?

1 : a surface seen in section (as in cross section) 2 : a hypothetical plane cutting a section.

What is the true shape of section?

To find the true shape of a section, it must be projected on a plane parallel to the section plane. For polyhedra, the true shape of the section depends on the number of POIs. The shape of the section will be a polygon of the sides equal to the number of POIs.

What is sectional view explain the importance of sectioning in solid?

A sectional view or a section looks inside an object. Sections are used to clarify the interior construction of a part that cannot be clearly described by hidden lines in exterior views. By taking an imaginary cut through the object and removing a portion, the inside features may be seen more clearly.

What is solid development?

When a solid is opened out and its complete surface is laid on a plane, the surface of the solid is said to be developed. The figure thus obtained is called a development of the surfaces of the solid or simply development. Development of the solid, when folded or rolled, gives the solid.

What is solid in graphics?

Introduction. An object having three dimensions, i.e., length, breadth and height is called as solid. In orthographic projection, minimums of two views are necessary to represent a solid. Front view is used to represent length and height and the top view is used to represent length and breadth.

What is a full section view?

Full Sections When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. 7 illustrates a full section. It is possible to section an object whenever a closer look intentionally is desired. Here is an object sectioned from two different directions.

What is Section plan?

Plan drawings are in fact a type of section, but they cut through the building on a horizontal rather than vertical plane. The direction of the plane through which the section is cut is often represented on plan drawings and elevations by a line of long and short dashes, called a section plane.

What is intersection of solid?

INTERSECTION OF SOLIDS. WHEN ONE SOLID PENETRATES ANOTHER SOLID THEN THEIR SURFACES INTERSECT AND AT THE JUNCTION OF INTERSECTION A TYPICAL CURVE IS FORMED, WHICH REMAINS COMMON TO BOTH SOLIDS. THIS CURVE IS CALLED CURVE OF INTERSECTION AND IT IS A RESULT OF INTERPENETRATION OF SOLIDS.

What is true shape of section in section of solids?

True shape of a section. The projection of a section on a plane parallel to the section plane will show the true shape of the section. ➢ When the section plane is parallel the H.P. or the ground, the true shape of the section will be seen in sectional top view.

What is section line in drawing?

Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details. These lines are drawn at full density and should be drawn at certain dimensions.

Why are solid principles important?

The broad goal of the SOLID principles is to reduce dependencies so that engineers change one area of software without impacting others. Additionally, they’re intended to make designs easier to understand, maintain, and extend.

What is the true shape of section of solid?

Section of above solids in simple vertical position (axis perpendicular to HP alone) by planes either inclined to HP or VP alone- True shape of section. A solid is a three dimensional object having length, breadth and thickness. It is Completely bounded by a surface or surfaces, which may be curved or plane.

What are the different types of sectional views of solids?

Types of sectional views of solids: By using the five different types of perpendicular section planes we .obtain the following five types of sectional views of solids: 1. Section of solids obtained by horizontal planes. 2. Section of solids obtained by vertical planes. 3. Sections of solids obtained by auxiliary inclined planes.

What is the intersection of the plane and solid called?

The intersection of the plane and the solid is called a cross section. For example, three different cross sections of a cube are shown below. square rectangle triangle Describing Cross Sections
