applications for graphical drawings Flashcards
What are the applications of manual and CAD techniques for?
Graphical drawings
Both techniques are crucial for effective design communications, ensuring accuracy, clarity, and feasibility in architectural and technical projects.
What do regular and irregular shapes define?
Forms and structures in both manual and CAD
These shapes are essential in creating accurate representations in drawings.
What types of lines are used in drawings?
Solid, Dotted
Different line types cover information such as hidden elements or symmetry.
What is the purpose of drawing to scale?
Ensure accurate representation of real world dimensions
Common scales include 1:50, 1:100, 1:500.
Why are standardized lettering styles important in technical drawings?
Ensure legibility
This is crucial for clear communication of information.
What measurements are included in dimensions?
Linear, angular, radial
These provide precise size and location details.
What are the types of 2D drawings?
- Orthographic
- Elevations
- Site layout plans
- Cross sections
- Systematic plans and layout
- Diagrams
These types help in different aspects of design representation.
What are the types of 3D drawings?
- Isometric projections
- Single point perspective
- Two point perspective
These techniques help visualize designs in three dimensions.
What does the setup in CAD involve?
Configuring units, sizes, grid settings, and templates before drawing
Proper setup is essential for accurate drawings.
What is the purpose of editing commands in CAD?
Modifying drawings using trim, extend, move, copy, mirror, rotate tools
These commands enhance flexibility in design adjustments.
What does zoom and pan enhance in CAD?
Visibility and control over detailed areas of the drawing
This is important for precision in intricate designs.
What is the function of layers in drawing production?
Organise drawings by assigning elements to different layers
This enables control over visibility, editing, and printing of specific elements.
What can be created from a zip floor plan in CAD?
3D extrusions
This is the basis for creating 3D models.
What do graphic conventions and standard symbols ensure?
