Lecture Autodesk inventor: Parallel projection

In parallel projection, all lines of sight are parallel, the object is positioned at infinity and viewed from multiple points on an imaginary line parallel to the object. The 3-D object is transformed into a 2-D representation or a plane of projection that is an imaginary flat plane upon which the image created by the lines of sight is projected.

Lecture Autodesk inventor: Oblique projections

Oblique projection is defined as a pictorial projection in which projectors are parallel to each other and inclined to the plane of projection at any angle other than right angle. Orthographic and oblique projections. In orthographic projections (both multiview and axonometric) the projectors are parallel to each other and perpendicular to the plane of projection.

Lecture Autodesk inventor: Orthographic projections

Projection is defined as an image or drawing of an object made on a plane. All drawings used in the field of engineering are based on the principles of projection. That is why engineering drawings are capable to precisely convey the external as well as internal features of objects in terms of their shape and size. Projections can be classified on the basis of line of sight and the position of plane on which the drawing is made.

Lecture Autodesk inventor: Visualization techniques - Multiview drawings

The chapter describes how to create one-, two-, and threeview sketches with traditional tools and CAD. Also described are standard practices for representing edges, curves, holes, tangencies, and fillets and rounds. The foundation of multiviews is orthographic projection, based on parallel lines of sight and mutually perpendicular views. Also introduced in this chapter are visualization techniques that can be used to help create and interpret multiviews.

Lecture Autodesk inventor: Auxiliary views

An auxiliary view is an orthographic view that is projected onto any plane other than the frontal, horizontal, or profile plane. An auxiliary view is not one of the six principal views. To show the true size and shape of surface ABCD, an auxiliary view can be created by positioning a line of sight perpendicular to the inclined plane, then constructing the new view.

Lecture Autodesk inventor: Finding an auxiliary view

For some objects, an auxiliary view must be created before a principal view can be drawn, using a technique called reverse construction. Auxiliary views can be used to draw a view in a specified direction. To create a view of an object in a specified direction, find the point view of the line of sight.

Lecture Autodesk inventor: Section views

The use of section views are powerful aids in the design and documentation of products and construction. There are many different types of section views that can be used to describe parts. Standards and conventions must be closely followed when creating section views.

Ebook Interactive computer graphics (5th edition): Part 1

Interactive computer graphics: A Top-Down approach with shader-Based OpenGL®, is the only introduction to computer graphics text for undergraduates that fully integrates OpenGL 3.1 and emphasizes application-based programming. Using C and C++, the top-down, programming-oriented approach allows for coverage of engaging 3D material early in the text so readers immediately begin to create their own 3D graphics. Low-level algorithms (for topics such as line drawing and filling polygons) are presented after readers learn to create graphics.
