Choosing the right tool for angled geometry Which dimension tool should be used to place the measured length of an angled line (its true length along the line), rather than its horizontal or vertical projection?

Introduction / Context:
When dimensioning sloped features, it is crucial to communicate the true length along the feature, not just horizontal or vertical components. CAD tools provide specific commands to ensure the dimension text reflects the correct measurement orientation.

Given Data / Assumptions:

• The geometry is a straight, angled line segment.
• We need the true length along that segment.
• Standards require clarity and avoidance of misinterpretation.

Concept / Approach:
The Aligned dimension tool measures the distance between two points along the line connecting them. By contrast, Linear dimensions report horizontal or vertical distances only, and Angle dimensions report degrees, not linear distances. Radial is reserved for circles and arcs.

Step-by-Step Solution:

Verification / Alternative check:
Compute the length using distance = sqrt((dx)^2 + (dy)^2) from endpoint coordinates. The CAD result and manual calculation should match.

Why Other Options Are Wrong:

• Angle: Gives the angle in degrees; no length.
• Linear: Reports projections along X or Y, not the slanted distance.
• Radial: For circular features only.

Common Pitfalls:
Accidentally using Linear can cause under- or over-stated dimensions if the reader assumes true length. Always verify that “Aligned” is selected for sloped segments.

Final Answer:
Aligned
