Engineering Drawing And Plans Simulations
A collection of interactive 3D visualizations and simulations to help you master concepts in engineering drawing and plans.
Introduction to Engineering Drawing - Theory & Concepts - Line Types
Overview of drawing instruments, line types, lettering, geometric constructions, and historical context.
Interactive Line Types

Scales and Paper Sizes - Theory & Concepts - Paper Size Visualizer
Understanding standard ISO and ANSI paper sizes, reduction and enlargement scales, and drawing scale interpretation.
ISO A-Series Paper Visualizer
See how each standard paper size relates to the original A0. The aspect ratio is always 1:√2.
Scales and Paper Sizes - Theory & Concepts - Architectural Scale
Understanding standard ISO and ANSI paper sizes, reduction and enlargement scales, and drawing scale interpretation.
Architectural Scale Simulator
Adjust the scale and the measured length on paper to see the real-world dimensions.
Calculation:
5 cm (paper) × 100 (scale ratio) = 500 cm (real) = 5.00 m (real)
Orthographic Projection - Theory & Concepts - Orthographic Viewer
Principles of multi-view projection, First and Third Angle projection systems, the six principal views, and the glass box concept.
Interactive Orthographic Projection
Pictorial Drawings - Theory & Concepts - Pictorial Viewer
Detailed analysis of Isometric, Oblique, and Perspective drawings, including mathematical scale factors and projection methods.
Interactive Pictorial Viewer
Sectional and Auxiliary Views - Theory & Concepts - Sectional Viewer
Advanced techniques for visualizing interior features through sectioning and determining true shapes of inclined surfaces via auxiliary views.
Interactive Sectional View
Slide to move the cutting plane.

Building Utilities Plans - Theory & Concepts - M E P Overlay Viewer
Detailed exploration of MEP (Mechanical, Electrical, Plumbing) systems layouts, panel schedules, and single-line diagrams.
MEP System Coordination Viewer
Toggle the building systems below to see how they coordinate within the structural envelope.
Building Utilities Plans - Theory & Concepts - Lighting Layout
Detailed exploration of MEP (Mechanical, Electrical, Plumbing) systems layouts, panel schedules, and single-line diagrams.
Lighting Layout Simulator
Total Lumens Req: 52,083
Exact Fixtures: 16.28
Suggested Grid: 5 x 4 (20 Fixtures)
The grid shows a suggested even layout. Dimmed fixtures indicate extra lights needed to complete a symmetrical grid.
Civil and Topographic Plans - Theory & Concepts - Topographic Map
Interpreting topographic maps, contour lines, elevation profiles, highway stationing, and earthwork calculations (cut and fill).
Topographic Map & Elevation Profile
Topographic Map (Top View)
Elevation Profile (Section A - A')
Observation: Move the slider to change the location of the cross-section cut (A-A') on the map. Notice how the elevation profile on the right accurately reflects the peaks (concentric circles) and valleys (V-shapes) that the red line intersects on the left.
