Drawing Sheets and Scales Flashcards
What are the two common placements for title blocks on architectural sheets?
On the side (usually preferred) or across the bottom.
Why is placing the title block on the side typically preferred?
It leaves a more useful drawing area with a simpler aspect ratio.
Why should drawing sheets still be organized for print even in the digital age?
Drawings are often printed for use on site or by various professionals.
Where should the most important elements of a drawing be placed?
Near the title block, typically on the side where the sheet is flipped open.
How are architectural drawing sheets typically numbered?
Using a hierarchical system like A1.1, A1.2, etc., to allow for easy additions.
Why not use simple sequential numbers (A1, A2, A3, etc.) for sheets?
Adding a new sheet in the middle would require renumbering all subsequent sheets and references.
What information is typically included in the title block?
Project name, drawing name, sheet number, architect’s info, consultant info, issue and revision dates.
Why should each drawing on a sheet have its own scale?
So that changes in size do not make a shared scale inaccurate.
What is a graphic scale used for?
To determine scale on-screen when printed scale may be unreliable.
What is a north arrow and when should it be used?
A symbol indicating north direction; used on plans but not on sections or details.
What is the purpose of consistency in naming and labeling drawings?
To avoid confusion and make navigation between sheets easier.
What are standard architectural sheet sizes?
24x36 and 30x42 inches.
Why are 24x36 and 30x42 inch sheets commonly used?
They balance space for drawings with manageability for printing and viewing.
What scale is typical for floor plans?
1/4” = 1’-0”, sometimes 1/8” = 1’-0” for larger projects.
What scale is used when an entire building won’t fit on one sheet?
A smaller scale such as 1/32” or 1/40” is used as a key plan to reference larger drawings.
Why use key plans?
To provide context and navigation aid for detailed or partial drawings.
What is the typical scale for wall sections?
3/4” = 1’-0”, sometimes 1/2” or 1” depending on detail.
What scale is used for interior elevations?
Typically 3/8” = 1’-0” or 1/2” = 1’-0” depending on detail.
What are typical scales for construction details?
1½” = 1’-0”, 3” = 1’-0”, and sometimes larger for millwork.
Why avoid unusual scales like 3/16” or 3/8”?
They are harder to interpret and less common.
What is a column line and why is it important?
A reference grid used for layout, dimensioning, and navigation in plans.
What do column lines help with?
Referencing locations quickly and organizing dimensions.
What are tags in construction drawings?
Symbols that reference other drawings or schedules for more detail.
Why use tags instead of repeating information?
To centralize updates and avoid inconsistencies.
