An isometric projection causes dimensions along the three principal edges to be foreshortened to approximately 87 percent of their true length.

Question

Quizplus · Accepted Answer

In an isometric projection, dimensions along the three principal axes (x, y, and z) appear foreshortened because the angles between the projection of the axes are equal, leading to a reduction in length to approximately 82% (more precisely, 81.65%) of their true size, not 87% as stated. The slight discrepancy in the percentage does not change the truth of the foreshortening effect in isometric projection.
