Use an original box’s width, height, depth and top mark to check view identity, distinguishing orthographic views from perspective illustrations.

Three pictures on a comic design page need not depict three different objects. First establish whether the caption specifies orthographic views, then compare shared dimensions and feature locations. This differs from cutaway transparency or exploded assembly diagrams. ManYue is not expected to generate a 3D model, and an illustration is not a manufacturing design or a source of real dimensions from pixels.

## Identify view type and viewing direction first

Record work, edition, chapter/page, title and labels for front, top and right-side views. Use an orthographic reading only when the caption or sufficient conventions support it; do not demand equal projected lengths from three perspective illustrations. Placement can follow first-angle or third-angle conventions, so a drawing on the right is not automatically the right-side view. Prioritise labels and projection information. If unspecified, retain candidate directions and unresolved evidence. Preserve the full group rather than cropping one rectangle and deciding from imagination whether it is top or front.

## Pair width, height and depth with their views

Our original box has width 6, height 4, depth 3 in illustrative units only. Front shows width 6 and height 4; top shows width 6 and depth 3; right side shows depth 3 and height 4. Make an external mapping: width links front/top, height links front/side, depth links top/side. The side’s horizontal 3 is not another width, and a top view lacking height does not mean the object has none. Numbers are specified, not measured from a ManYue screenshot. They establish no real tolerances, wall thickness or materials.

## Matching dimensions alone do not prove object identity

Rectangles 6×4, 6×3, 3×4 are compatible exterior dimensions, not proof of identical internals or all details. Another box could share them. Check title, identifier, material description and common features instead of declaring one edition from matching ratios. Separate states such as open/closed; an unfolded lid’s footprint is not automatically a changed body width. Without a shared-scale statement, do not compare screenshot pixels directly. First establish whether views use the same scale; otherwise mark that pixel evidence insufficient for a dimensional-error claim.

## Locate top features under the declared orientation

Add a small circle to the self-made top view as a surface mark only, stipulated near the front and toward the object’s left, not a hole or internal passage. Identify which top edge meets the front and which direction is object-left before locating it. The front view need not show the same circle: the top mark may not appear circular from the front. Do not extend it into a through-hole. Hidden lines, centre lines or omission depend on the drawing’s conventions and remain unknown if unspecified. Visibility and physical existence differ; absence from another view does not establish disappearance.

## Check correspondence with one changed dimension

In a control, change depth alone from 3 to 5 while width 6 and height 4 remain. Front stays 6×4, top becomes 6×5, right side 5×4. Changing only the top while leaving side 3×4 creates an inconsistency needing explanation; first verify common state and edition. This is a manual rewrite, not a change saved into the work or app-linked dimension update. A separate control changes width to 7, affecting front/top rather than directly changing the side’s depth/height. Keep these controls separate so the specific shared relationship remains visible.

## Do not mix section and perspective conventions into this test

A hatched section reveals an interior information layer, so its cut appearance need not match an uncut front line for line. Perspective foreshortening also prevents direct equal-length checks; identify the view before deciding what can be compared. An exploded drawing’s separated footprint is not assembled size. Unlike the earlier cutaway and exploded-view tasks, this task checks width/height/depth shared by explicitly orthographic views. On a mixed page, label each image’s type separately instead of treating one “multiple views” heading as erasing every convention difference.

## Troubleshoot cropped labels and display scaling

When views seem inconsistent, restore the full page and check view labels, scale, edition and state before enlarging dimension text. Independently scaled screenshots cannot establish a deformed box from pixel ratios. If the source explicitly prints 6 and 7, retain both locations and context rather than immediately blaming rendering. A cropped caption means missing projection conventions; a manual description must retain that condition. Three simple external sketch boxes may aid understanding, but numbers must come from the problem or a labelled control. A neat redraw does not establish source consistency or supply an unspecified depth.

## Exit and return to check shared dimensions pairwise

Exit the reader and return to the complete group. Identify again which two views share width, height and depth, then check orientation conditions for the top mark. Recalculate the depth 5 and width 7 controls and explain why the front can remain unchanged in the first. Retain six items: diagram identity, view type, directional conventions, dimension mapping, feature evidence and unknowns. Completion means another reader can reconstruct the mapping from labels and stipulations, not that the drawing is manufacturable, its internals fully known or a real device’s safe dimensions established.
