Principle for drawing a revolution surfaceA revolution surface is a surface created by
the rotation of a profile around an axis.
Example of a revolution surface.
In the CAD module, click on "new
file" *For this example, use the dimension parameters of the default
blank. Create a new window and arrange the screen as on the following view
attributing the "perspective" view to the smallest window.
Activate the "realistic rendering" on the " XY " view.
Draw a curve like that in the example below.
Select this curve which will be the profile of
the surface.
Click on the icon: " surface " 
then : " revolution surface " 
The following window offers to give you the
profile's angle of revolution around the axis.
Leave the default value of 180° and click on
" OK "
Click two points on the axis of the " X
" to indicate the axis around which the profile that will create the
surface will turn. (For this example, make a horizontal axis at the level
of the lowest point of the profile.)
Once the second point is validated the surface
is calculated. The rotation is in the trigonometric direction (anti-clockwise).
You
can create a revolution surface around the " Z " axis. To do
this, just create a rotation point in the place of a rotation axis. To
creat a point, just click once, then click on the right button of the
mouse.
