Creating drawings in Catia - View toolbar - 2

Remaining tools in the view toolbar can be accessed using the same path i.e. Insert > Views or by using the views toolbar itself.
Tools in Views toolbar
Detail view and Detail view profile

Detail and Sketched detail profile can be used to add an enlarged view from an existing view on the sheet. The scale of the view by default is 2:1.
Creating detail and sketched detail profile using a view
In case of detail, a circle is used to select the area, while in case of sketched detail profile, you can select the area to be enlarged by drawing a closed profile using lines around the region. 

Quick detail view and Quick detail view profile

These are so similar to the detail and sketched detail profile that you may mistake them as the same. However it is not the case. Here, the profile i.e. a circle or a closed profile that you make is shown complete along with the detail that is created.
Quick detail and Sketched quick detail profile
While in case of detail and sketched detail profile the outline is shown only where it touches the portion drawing view.

Clipping, Sketched clipping profile, Quick clipping and Sketched quick clipping profile

If you do not wish to keep the view, and instead have only section of a view in the drawing, you may first create a view and use any of these four options to extract only a portion as clipped view on sheet.
Creating quick clipping view, rest can be created in same manner
In case of clipping, the view is not enlarged but is only clipped from the original view. The difference between them all is the same as we observed previously in case of detail, quick detail etc. 

Broken view

In case where one part dimension is much larger than the other, such that a reduced scale may not present sufficient detail. Or for exceptionally elongated parts with constant section, we may use a broken view. Consider a case of shaft that is 4 meter long with some feature on both the ends with constant section and no feature in the middle and you want o create drawing for this on an A4 sheet. It may make sense to use a broken view in that case.
Creating broken view
The first click defines the position where you want to apply the broken view, by moving the cursor, and by using the second click you can choose whether if the broken section that needs to be removed is vertical or horizontal. Using third click, you can select the second borken point and with the fourth click the broken view is created.

Breakout view

The breakout view can be used to select a portion in an existing view. And the portion selected can be used to show the inner working /sections within the existing view. The breakout view can be applied on all views except section cuts, detail / clipping views and breakout views. To create the view, you need to make a closed profile. After the profile is made, a visualization window opens up that you can use it to drag the plane or select a line / axis etc. in any of the view to apply the cut plane and show the inner portion of parts / assembly.
Creating a breakout view
Instead of dragging the plane, you can make the cut plane selection with use of reference too. You can do so by clicking on the reference dialogue area. After this select a reference element on the drawing views in your drawing to position the plane, the selection made in this way is associative. When you specify a reference element, you would also be able to position the plane by specifying distance (from reference). If you position the plane using an axis as reference and the axis position modifies, the breakout view will be modified. The green arrow indicates the direction in which the breakout view is created.

Add 3D clipping

The 3D clipping is an interactive way of creating a view using an existing view. 3D clipping provides three options that you can use and these options provide much more flexibility for creating a view. Using this, you can create a view much like you created a section using breakout view. One of its options (back clipping plane) create a view, and the other two options can create section view as well as view depending of position of planes. The view in the drawing from which you wish to create a view / section needs to be pre-selected. Subsequently, you can use the add 3D clipping tool.
Add 3D clipping
  • Back clipping plane - As the name indicates, it clips the part behind the back of the plane. The back clipping plane option, creates a view and not a section. The view in this case is limited to position of the plane. So anything between the plane and direction of the blue arrow is shown while the rest is simply eliminated.
  • Clipping by slice - The option is just like clipping plane, with the difference that you can limit the view using two planes. So anything between the planes will be shown. The first plane in the direction of view creates the section while the second plane limits the view and works just like back clipping plane.
  • Clipping box - Using clipping box, you can not only limit clipping in the direction of viewing, but also sideways. The side planes i.e. planes in the direction perpendicular to the view act as clipping planes while two other planes act as clipping by slice i.e one as back clipping plane and other as section plane.
You can double click on any manipulator and the face will turn green and will allow you to make selection using reference from the views on drawing.
