How do you draw a projection of a solid?
How do you draw a projection of a solid?
the solids are placed initially in the simple position and then one or two auxiliary planes are setup to obtain the views in the required position. one of the square faces containing that edge is inclined at 300 to HP and the edge on which it rests being inclined to 600 to VP. Draw its projections.
What is the projection of solid?
1. -The shape of the solid is described by drawing its two orthographic views usually on the two principle planes i.e. H.P. & V.P. PROJECTIONS OF SOLIDS Definition of Solid: A solid is a three dimensional object having length, breadth and thickness.
How do you draw a section of solids in engineering drawing?
It is cut by a section plane, perpendicular to the VP, inclined at 45º to the HP and bisecting the axis. Draw its sectional top view, sectional side view and true shape of the section.
What is generator in projection of solids?
Generators: Imaginary lines generating curved surface of cylinder & cone. Solids of revolution: Cylinder Cone Base Apex Base Generators Axis Axis.
What are the possible positions of solids?
Engineering Drawing Questions and Answers – Projection of Solids in Simple Position – 1
| Position of solids | Front View | |
|---|---|---|
| 1. | Square pyramid- axis perpendicular to V.P | Rectangle |
| 2. | Cylinder- base parallel to profile plane | Circle |
| 3. | Triangular prism – axis perpendicular to H.P | Square |
| 4. | Cone- base parallel to V.P | Triangle |
When the axis of solid is perpendicular to HP?
Explanation: When the axis of solid is perpendicular to H.P it is indirectly saying that the base is parallel to the horizontal plane so the projection on to it gives true shape of the base and then we can project and find the other dimensions. 4.
How will you classify sections of solids?
Solid figures are classified into prisms, pyramids, cylinders, spheres and so on. A prism is a solid that has two congruent bases which are parallel faces. The other faces of the prism are in the shape of rectangles.
Why the solids are sectioned in engineering drawing?
ONE OF ENGINEERING APPLICATIONOF PROJECTION OF SOLIDS IS SECTION OF SOLIDS. SECTIONING A SOLID. An object ( here a solid ) is cut by some imaginary cutting plane to understand internal details of that object. The action of cutting is called SECTIONING a solid & The plane of cutting is called SECTION PLANE.
What are the types of solids in drawing?
In orthographic projection, minimums of two views are necessary to represent a solid….Polyhedra
- Regular Polyhedra.
- Prisms.
- Pyramids.
What are the different positions a solid can take wrt the reference planes?
The following are the different positions which the axis of a solid can take with respect to the reference planes:
- Axis perpendicular to HP and parallel to VP.
- Axis perpendicular to VP and parallel to HP.
- Axis parallel to both HP and VP, i.e., axis perpendicular to a profile plane.
- Axis inclined to HP and parallel to VP.

What can you do with solidedit in Autodesk?
Edits faces and edges of 3D solid objects. You can extrude, move, rotate, offset, taper, copy, delete, and assign colors and materials to faces. You can also copy and assign colors to edges. You can imprint, separate, shell, clean, and check the validity of the entire 3D solid object ( body ).
