Technical drawings are blueprint-style drawings that show information about a product, from dimensions like height, width, and depth, to specific information like materials or assembly details.
Technical drawings are widely used in many industries by professionals including architects, engineers, CAD technicians, product designers and mathematicians. Some of these professions can be divided into several professions that are dedicated to technical drawing.
Below is a list of the various types of technical drawing and their uses. Now that this entry is on architecture, the list of technical drawings we will review are architectural only. Only we will go through the list of technical drawings focused on architecture.
What are the types of technical drawing plans?
The types of technical drawings are as follows:
- Blueprints of the floor
- elevations
- Cross / Longitudinal Sections
- detail drawings
- 3D detail drawings
What are technical plans in architecture used for?
In the world of architecture, architects and architectural technologists/technicians produce drawings for the design of buildings. These architectural specialists specialize in both preliminary sketches for presentation and technical drawings for assembly instructions, material specifications, and sizing.
Fabricators or construction workers use architectural technical drawings to join building components, or to construct a building in accordance with what is specified on the drawings.
floor plan: A floor plan is like a building map and shows the reader how the building is laid out, the floor plan can be used to see the positions of building components such as walls, windows, doors, room sizes, and loose components such as furniture.
A fixed component is called a dead load, and a loose component, such as a chair or table, is called a live load. People using and moving around the building are also considered live loads.
All technical drawings of a building can be used together, a floor plan can be used to see the positions in the “x” and “y” directions of building components, and a complementary or cooperative elevation drawing can be used . To see the direction of the “z” axis of the same components.
Because the “x” and “y” axes are the limited nature of the floor plan, the floor plan only shows one level of a building at a time. Therefore, there is a separate plan drawing for each floor, including the roof level and the foundation level.
Measures: Measurements on a floor plan are represented by dimension lines, there are different styles of dimension lines, but they all serve the same function; to mark the distances in the rooms and the exact numerical positions of the doors and windows, as well as the widths and sizes of the walls.
Floor plans display a series of symbols. the grids, for example, are used to help keep a building aligned. Grid lines can also be used to mark column and wall positions on the grid lines.
Other information shown on a floor plan is the text information. This is a body of text that could have an arrow symbol pointing to a component and the text would explain the properties of the components, for example a wall spec.
The text would then describe what the wall is made of by listing each of the materials and their dimensions. For example, a hollow wall made up of 102.5 mm brick, a 75 mm cavity filled with rock wool insulation, 100 mm of 7-knot block.
The text information may also direct the viewer to verify specific detailed drawings about the building component. Text information mentioning the cavity wall may mention something like “See Wall Detail 1”, and the viewer can refer to the corresponding detail sheet to better understand the composition and construction of the wall.
The floor plan also shows references for the components In the building, this is especially useful when there are a number of the same components used, for example, the internal doors of a house. A bathroom door may be different from a bedroom door. The exterior door is definitely different than the interior doors, but it is probably different than the back door that leads to the garden, for example.
Another example of a symbol on the floor plan that works in conjunction with other drawings is the symbol for sectional viewthis marks a section of the building that we can see as if we had cut out a piece of the pie and were looking at the inner layers of the pie, or the internal cutaway view of the building.
This information is only the beginning of the graphic representation of plans in architecture. Did you know the symbology of the plans?
