Descriptive Geometry, taught on a real drawing board
Mongean projection, traces of planes and lines, true lengths and solids — one-to-one and online, with frontal, horizontal and profile views side by side on a purpose-built board. Geometria Descritiva A for the Portuguese programme; technical drawing for everyone else.
What this covers in detail
Dihedral representation
Projection types and the dihedral system: points, lines and planes, their traces, intersections, parallelism and perpendicularity, and the auxiliary methods.
Solids, sections and shadows
Plane figures and solids in dihedral projection, sections and truncations, a line meeting a solid, and own and cast shadows.
Axonometry
The axonometric representation system — its planes and axes — and drawing figures and solids in axonometric projection.
Descriptive Geometry is a subject you learn by drawing, and most online tutoring cannot draw with you. This one can: a digital estirador where every construction is built live, rotated in 3D to check it, and exported as a PDF sheet. Lessons are priced at the high-school rate — the level Descriptive Geometry A is taught at.
What this covers
A purpose-built digital estirador
Frontal, horizontal and profile views side by side. Constructions are drawn live in the lesson, not shown as finished diagrams.
Check it in 3D
Rotate the solid to see whether the projection is right before committing it to the sheet — the step that is impossible on paper.
Built for the Exame Nacional
Past-paper constructions, the standard notation, and the timing the exam demands. The plan follows the programme.

Common questions
Do I need to install anything?
No. The drawing board runs in the browser. A tablet with a stylus helps but a mouse works fine.
Is this only for the Portuguese exam?
No. Geometria Descritiva A with the Exame Nacional in view is one audience, and the method and notation there are exactly what the exam expects. The same projection work is the technical drawing taught on design, architecture and engineering courses elsewhere — the board and the approach do not change, only the name.
