Creating an Auxiliary View

This task will show you how to create an auxiliary view

Many objects are of such shape that their principal faces cannot always be assumed parallel to the regular planes of projection. Creating an auxiliary view allows showing the true shapes by assuming a direction of sight perpendicular to planes that are perpendicular of the curves. This auxiliary view, together with the top view, completely describes the object.


Before You Begin, make sure you customized the following settings:

De-activate the Grid icon from the Tools toolbar (bottom right).

View names and scaling factors:
Go to Tools->Options ->Mechanical Design -> Drafting option (Layout tab) and check the View name and Scaling factor options.

3D colors inheritance
Go to Tools->Options->Mechanical Design->Drafting option (Generation tab) and un-check the 3D colors inheritance option.



Open the GenDrafting_part.CATDrawing document.


Before You Begin:
Make sure the right view is active (use double-clicking).


1.   Click the Auxiliary View icon from the Views toolbar (Projections subtoolbar).



Sketch the representation of the plane. In this case, click an edge on the right view. 

You could also click a point and then an edge.

Both the 3D surface and the sketched plane are associative.

The selected edge becomes a line that you can position where desired using the cursor. This line/callout will be automatically used as the plane. 


3.   Click to position the callout.

The reference plane is automatically positioned according to the selected edge.

Positioning the auxiliary view callout amounts to defining the auxiliary view direction.

4.   Click to position the auxiliary view.

Before clicking, as you move the cursor within a zone perpendicular to the plane, a preview of the auxiliary view to be created simultaneously appears. This view will be automatically positioned accordingly. This is also true when creating a section view or a section cut.

You can also move the cursor outside the zone perpendicular to the plane and position the view where you want.

Note that the callout can be inverted or graphically modified

You can move the view after it has been created. For this: 

1. Right-click the frame of the view not to be aligned.

2. Select the Do not align view option from the displayed contextual menu.

3. Drag the view to the desired location.



You can choose the auxiliary view axis orientation. For this go to Tools -> Options -> Drafting -> Layout and check the Auxiliary and/or section views orientation according to profileoption.
