Profile Editor
When a point or segment is selected in the Cross-section View, Profile View displays plot of
the current
parameter for the selected object. For example, when a point is selected in cross-object,
Profile View will show plot of the first coordinate against z.
To change the parameter currently displayed in the Profile Editor, use
background menu (right mouse button) or select
another option from the Current Profile combo box on Profile Page of the
Form View. This combo box is not available when there are no objects
selected in Cross-section View or the selected object has no editable parameters,
like straight
line, for example.
The Profile editor has common functionality of a
2D editor with the
difference that modifications with the mouse or dialogs apply only
to vertical direction. Horizontal changes can be made by modifying
base knots and this change will apply to all profiles in the object.
The base knots are shown at the top of the Profile Editor window. They
are drawn with red ticks. To modify a base knot drag the tick with the mouse or edit the position using Axial Knots Editor available in Menu > Base
> Modify. To add a new knot select Menu > Base > New knot command and
click in the profile view at x position where you would like to put
it. The knot's position can be adjusted precisely using the above
dialog.
Another method to add a new knot is to set the cross position to the needed
point and press "New knot"
button on the Command Page of the form.
The blue vertical line in Profile View shows current cross position. It can be
moved with the mouse. Precise cross position can be set by using
correspondent edit box in the Form View. When cross position coincides with one of
base knots, modifications in the Cross-section View apply to joints of 3D surface
strips (See also Cross-section Editor). This is equivalent to selecting correspondent
point in profile editor and modifying it.
Note that for the sake of saving screen space profile editor is not
isometric, which means that the strip normally is either stretched or contracted in vertical
direction. Just remember that actual segments are always either lines or arcs. The
actual proportions can be observed in 3D View.
