![]() The shape of the cross section depends upon the type of cut like horizontal or vertical. When we cut any 3D object horizontally or vertically, we get a 2D face of that figure. There are so many ways to see the different sections of the 3D shape- 1. We can see that the front, top and side view of the above image is completely different and we cannot see some of its faces then also we can say that this figure is made up of four cubes. But then also we can assume that which shape it is, this is called Visualization. When we see any 3D shape from one side then some of its parts are not visible to us. When we draw the shape on the isometric sheet with the measurements proportional to the original figure then it is said to be Isometric sketch. The isometric sheet is the sheet made up of dots which makes the equilateral triangles. The front and back faces are of the same size.Īll the edges are appearing as of the same length but their measurements are different. Points to remember for the oblique sketch. Step 3: Now, join the respective corners, to form a cube. ![]() Step 2: Draw the opposite face of the same size which is offset to the front face. Step 1: First, we need to draw a square of 2 × 2 on a grid sheet. When we draw a shape in such a way that we are not able to see some of the faces of the 3D shape and the size of the length is also not equal but we are able to recognize that this is a cube then this is called an Oblique Sketch.ĭraw the sketch of a cube with a side of 4 cm each. We can open a 3D shape from its edges to get the net of that figure.ĭrawing Solids on a Flat Surface (2D representation of 3D Shapes)Īs you know that the 3D shapes are the shapes which occupy some space but we can draw the 3D shapes on the flat surface also by some techniques. Different figures have a different type of nets. If we draw the structure on the 2D form and fold it to make a 3D shape then it is said to be the net of that figure. of Faces, Edges and Vertices in some common 3- D Shapes S.No. The singular form of vertices is the vertex. Vertices – The corners or the points where the edges meet with each other are the vertices of the 3D shape. The faces of 3D shapes are made by the 2-D shapes.Įdges – The line segment where the faces of the 3D shape meet with each other are the edges of that shape. Like the ball, box, tube etc.įaces – All the flat surfaces of the 3-D figure are the faces of that shape. length, breadth and height are called 3 –Dimensional Shape. The figures which have three dimensions i.e. length and breadth, hence these are called 2 Dimensional Shapes. The figures which we can draw on a flat surface are called Plane Figures.
