DESCRIPTION
Basic introduction to Paraline Drawings, with reference to basic shapes and its construction in technical drawings

PARALINE DRAWINGS
All vertical lines remain verticalAll parallel lines remain parallelAll lines parallel to X,Y,Z axis can be drawn to actual/scale dimensionsAll the vertical and horizontal lines represent the true dimension
ISOMETRIC 30/30 AXONOMETRIC 30/60PLAN OBLIQUE 45/45ELEVATION OBLIQUE 90/45
3 dimensional drawings that shows 3 elevations(plan/top, 2 elevation) of the object or building .
ISOMETRICAll three visible surfaces have equal emphasisRelatively inflexibleOrthographic plan and elevations can never be used.
AXONOMETRICOne vertical plane receiving more emphasis than the otherFlexibility in choice of viewOrthographic plan and elevations can be used.
PLAN OBLIQUEHigh angle of view Horizontal planes receive more emphasisEqual importance to vertical planesOrthographic plan and elevations can be used.
ELEVATION OBLIQUEA vertical plane remains parallel to the drawing surface.Shown in true size ( to scale)Should be the most significant face of the object/buildingOrthographic plan and elevations can be used.
ISOMETRIC DRAWINGS
AXONOMETRIC DRAWINGS
SHAPEIsometric view if the Shape is ELEVATION or PLANTRIANGLE
Shapes containing Inclined lines should be enclosed in a rectangle as shown. Then first draw isometric of that rectangle and then inscribe that shape as it is.
