CAD Practice — Creating Oblique Views In modern CAD systems, are oblique drawings inherently difficult because snap increments and grid based construction cannot be used, or can snaps, grids, and coordinate input still be leveraged effectively for oblique work?

Introduction / Context:
Oblique drawings are constructed by keeping a principal face in true size and projecting depth along a receding axis. In CAD, users often rely on grids, snaps, tracking, and coordinate input to create accurate geometry. The statement claims that such aids cannot be used for oblique views, implying that CAD makes oblique work unusually difficult.

Given Data / Assumptions:

• CAD platforms support ortho, polar, and object snaps.
• Polar tracking can be set to custom angles (e.g., 30, 45, 60 degrees).
• Absolute and relative coordinate input allows precise offsets on any axis.

Concept / Approach:
To create oblique drawings, set a polar tracking angle to the chosen receding direction and apply the required scale factor for depth (e.g., 1.0 for cavalier, 0.5 for cabinet). Grids can remain orthogonal to the sheet while snaps and tracking guide the receding axis. Object snaps (end, mid, center, tangent) still function to anchor edges and arcs accurately.

Step-by-Step Solution:
1) Enable polar tracking and add the desired oblique angle.2) Draw the front view at true size using standard snaps.3) Enter depth coordinates using the selected scale (e.g., @d/2<angle for cabinet).4) Use object snaps to complete edges and curved features.

Verification / Alternative check:
Test geometry built with relative polar coordinates matches intended depths and aligns cleanly to snapped anchors, demonstrating that CAD tools support oblique methods well.

Why Other Options Are Wrong:
Correct contradicts practical CAD workflows. Only true in 2D, not 3D and Only with special plugins are unnecessary restrictions. Partially correct understates CAD capability.

Common Pitfalls:
Forgetting to apply the cabinet 1/2 depth factor; failing to add the custom polar angle before drawing depth lines.

Final Answer:
Incorrect
