Description
Adding control points is often the easiest and best way to modify the shape of a curve
segment within Fidelity Pointwise. When adding one or more control points to a
segment, the location of the cursor within the Display window largely affects where and how the new control point(s) will be placed.
When the cursor is placed before the beginning of a segment (indicated by a control point enclosed in a yellow circle) a vector will appear which will show
the current orientation of the cursor in relation to the segment beginning.
Left-clicking the cursor in front of the segment beginning will add a new control point at that location.
If the cursor is moved to a point after the end of the segment, a vector showing the orientation of the cursor in relation to the segment end will be
shown. Left-clicking on a point past either location, segment beginning or end, will create a new control point extending the existing segment. Depending on
the location of the control point and the selected Segment Type, the shape of the segment may also change.
Left-clicking the cursor after the segment ending will add a new control point at that location.
Adding a control point to the interior of a segment to change its shape requires that the cursor be placed at the location between the two control points
where it should be added. At this point, the segment in which the control point will be added should show up highlighted in pink.
Left-clicking the cursor between the beginning and ending of the segment will add a new control point, internal to the segment, at that location.
Once the location is left-clicked with the mouse in the Display window, the new control point will show up highlighted in pink on top of the
modified segment shape shown in yellow. A copy of the original segment will still be shown (in green) until the edits to the curve have been saved by
clicking OK. After clicking OK, the yellow copy showing the modifications to the curve will replace the old curve in the Display
window and in memory.
Once a position has been left-clicked, the current segment will be updated to show a new control point at that location (highlighted in pink).
