Difficulty: Easy
Correct Answer: Objects are entered at specific, uniform intervals on the grid
Explanation:
Introduction / Context:
CAD systems provide drafting aids to improve precision and speed. One such aid is SNAP, which constrains the cursor to land at fixed increments on a grid so that points and objects align consistently. Understanding SNAP helps new users avoid tiny misalignments and ensures dimensional accuracy across a drawing.
Given Data / Assumptions:
Concept / Approach:
SNAP defines a spacing (for example, 1 unit, 5 mm) that restricts input coordinates to multiples of that spacing. Cursor movement becomes quantized to the grid, allowing users to draw lines, rectangles, and other entities that fall exactly on intended coordinates. This differs from Object Snap (OSNAP), which locks to existing geometry features such as endpoints, midpoints, centers, and intersections.
Step-by-Step Solution:
Verification / Alternative check:
Contrast with OSNAP: OSNAP targets existing geometry features; SNAP constrains entry to a regular lattice whether or not existing features are present.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing SNAP with OSNAP, or forgetting to reset SNAP increments when switching scales, leading to unexpected point placement.
Final Answer:
Objects are entered at specific, uniform intervals on the grid.
