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.

Finding an Auxiliary View

Given: A multiview set of an object with an 

inclined surface Find: An auxiliary view showing the true size 

and shape of the inclined surface 

Step 1

Draw a reference line parallel to the edge view of  the inclined surface to be projected

Step 2

Draw perpendicular projection lines from the  inclined surface

Step 3

Draw a second reference line at a “convenient”  location between the view being projected from  and an adjacent principal view

Step 4

Label the vertices of the inclined surface in the  adjacent view

Transfer the vertex labels to the edge view

Step 5

Measure, then transfer the vertex distances from  the principal­principal reference line (H­F) in the  adjacent view to the principal­auxiliary (F­1) 

reference line 

Step 6

Label the vertices in the auxiliary view, then  connect the vertices. This view gives the true  size and shape of the inclined surface
