Setting drawing limits: for an architectural “C” size sheet, which upper-right limits setting (with lower-left at 0,0) is appropriate for the sheet dimensions?

Introduction / Context:
CAD “limits” define the drawing's working area and are often set to match standard sheet sizes. For architectural work, the C-size sheet is commonly 18 inches by 24 inches (width by height in landscape or vice versa in portrait).

Given Data / Assumptions:

• Units are inches (architectural drafting).
• Lower-left corner is set to 0,0.
• We need the matching upper-right corner for a C-size sheet area.

Concept / Approach:
With 0,0 at the lower-left, the upper-right coordinate should match the sheet's width and height. For ARCH C, that is 18 by 24. This ensures Zoom All shows the whole sheet and that title blocks align to the work zone.

Step-by-Step Solution:

Verification / Alternative check:
Insert or draw a border sized 18×24; it should match the drawing limits exactly.

Why Other Options Are Wrong:

• 17,11: Close to ANSI B (11×17) or half-size combinations, not ARCH C.
• 34,24: Double-width; not standard C.
• 2,9: Incorrect by orders of magnitude.

Common Pitfalls:
Confusing ANSI and ARCH series; always verify whether the project uses architectural or ANSI sheet standards.

Final Answer:
0,0 and 18,24
