Top Front End
Find the missing orthographic view.
Top Front End (TFE), also called View Recognition or Orthographic Projections, presents an object using engineering views. You're given two of the three standard views — top, front, and end — and must choose the correct missing view from four options. Solid lines represent edges you can see; dashed lines represent edges hidden behind the object.
Also known as: TFE, Top-Front-End, Orthographic Projections, View Recognition
Pick an answer above, then check it.
How Top Front End works on the DAT
- 1
Two of the three views (top, front, end) are shown for a single object.
- 2
You select the correct third view from four candidates.
- 3
Solid lines mark visible edges; dashed lines mark hidden edges.
- 4
The right answer matches the object line-for-line, including every hidden edge.
Why students struggle
- Keeping track of hidden (dashed) lines that don't appear in the other views.
- Aligning features point-to-point across the top, front, and end views.
- Reconstructing depth from flat 2D drawings.
- Answer choices that differ by a single line.
Common mistakes to avoid
- Ignoring dashed (hidden) lines entirely.
- Confusing depth direction between the front and end views.
- Failing to align features across views.
- Rushing past near-identical answer choices.
Proven strategies for Top Front End
The tactics our highest-scoring students use to speed through TFE without losing accuracy.
1. Align the views point-to-point
Width carries between the top and front views; height between the front and end. Drop alignment lines so every feature in one view maps to the same place in the others.
2. Solid vs. hidden, deliberately
Mark which edges must be visible (solid) and which must be hidden (dashed) before you look at the answers. A single wrong solid/dashed line eliminates a choice.
3. Build the solid, then project
Use the two given views to reconstruct the 3D object in your head, then project the missing direction rather than guessing line shapes.
4. Eliminate on one line
You rarely need to fully verify the right answer. Find the single distinguishing edge among the choices and cut everything that gets it wrong.
How PATCrusher helps you master TFE
TFE generator with every projection
Practice unlimited view-recognition problems and train the solid/hidden-line habit until it's reflex.
3D reconstruction in the solution
Each explanation rebuilds the solid object and shows all three views together, so you can finally see how the hidden lines come from.
