Auxiliary view clean-up in CAD: when you have created an auxiliary view, what is an efficient CAD technique to trim intersecting corners precisely to their meeting point?
-
A0 radius fillet
-
BHatch tool
-
CExtend tool
-
DGrips function
Answer
Correct Answer: 0 radius fillet
Explanation
Introduction / Context:After projecting geometry into an auxiliary view, lines may overrun their intersections. CAD drafters often need a fast, exact method to trim corners to a clean intersection without manually picking trim boundaries multiple times.
Given Data / Assumptions:
- Standard 2D CAD tools are available (fillet, trim/extend, grips, hatch).
- Goal is precise corner formation at the theoretical intersection.
- We are finishing the auxiliary outline, not applying materials or annotations.
Concept / Approach:Using a fillet command with zero radius acts as a combined trim-to-intersection tool. It deletes the overrun and forms a sharp corner at the exact intersection point. This is faster and more accurate than repeated trim and extend operations, especially on busy auxiliary views.
Step-by-Step Solution:
Invoke the Fillet command and set radius = 0.Select the two lines that should meet at a sharp corner.Confirm the preview shows a clean intersection; apply the operation.Repeat along the auxiliary perimeter to finish corners neatly.Verification / Alternative check:Use object snaps to check that resulting corners lie precisely at the intersection of the original line extensions.
Why Other Options Are Wrong:
- Hatch tool: Fills areas; not for trimming geometry.
- Extend tool: Extends but does not trim both participants to the theoretical intersection automatically.
- Grips function: Useful for edits, but slower and less precise for repeated corner formation.
Common Pitfalls:Leaving a nonzero fillet radius by mistake, which rounds the corner; always verify radius = 0 before use.
Final Answer:0 radius fillet
