Learn how to develop a site plan from a site survey plan in AutoCAD, including building shape, position, key dimensions, north and scale, and notes on septic tank.

Explore footing layout in a simple residential ground floor plan, linking column grid intersections to footing positions. Understand grid lines, center lines, and baseline dimensions that locate and size footings.

Read the ground floor plan by tracing grid lines and column positions, identify exterior and interior walls by thickness, and locate entrance and exit doors d1 and d2 and windows.

Learn to read floor plans by identifying grid lines, dimensions, and room tags. Interpret interior sizes and spatial connections, noting veranda, dining, bedrooms, kitchen, windows, and ventilation.

Explore the toilet plan view in AutoCAD drafting part two six and eight, detailing door D3, fan light, floor hatch, water closet, shower, floor drain, and the lavatory concept.

Learn to read the front elevation by analyzing the ground and first floor plans, noting gates, parapet walls, railings, and window/door layouts (W1/D1), then explore a 3D view.

Explore how to read the left side elevation from ground and first floor plans, noting stairs, landings, doors, windows, and a balcony. Relate elevations to plan views in AutoCAD drafting.

Master AutoCAD section cuts by projecting vertical construction lines, rotating the plan view, and identifying foundation width, beams, slabs, and hatch patterns in a sectional elevation.

Explore a ground-floor section cut, tracing wall types, an arch opening, a door and a window, and lintel and cell details, while examining height verification through doors and windows schedules.

Explore how the section cut reveals slab and beam forming a T shape with parapet wall and columns. Learn to spot visibility changes and the intentional drawing mistakes, including D2.

Analyze the arch section cut, detailing the lintel, brick wall, and concrete elements through 3D and 2D views, with elevations, hatch patterns, and a four feet by eight feet opening.

Explore how a section cut clarifies floor and foundation, highlighting monolithic slab and beam versus separation lines from casting days, plus plinth beam, plain cement concrete, and earth fill details.
