This task shows you how to create and visualize curves on surfaces in
order to analyze the surface shape and curvature variations. |
 |
Open the
HighlightLines1.CATPart document. |
 |
-
Click the Highlight Lines Analysis icon
.
The Highlight Lines dialog box opens.
|
| |

|
| |
-
Select one or more surfaces to be analyzed.
|
| |
-
Select the analysis type and the highlight type.

| By Angle |
Tangent |
The compass plane intersects the surface at a
given point. Then the tangent to this intersection is calculated.
Therefore, the angle is computed between the first direction of
the compass and the tangent to the intersection.
The tangent in each point of the created line is
defined through rotations of the angle pitch.
 |
| Normal |
The angle is computed between the Z compass
direction and the normal to the surface.
The normal to the surface in each point of the created
line has the same angle pitch in a specified direction.
 |
| By Point |
Tangent |
Define the points on the surface.
The angle is computed between the first direction of the compass and
and the tangent to the intersection. The computed angle remains
constant at any selected point on that particular highlight line.
 |
| Normal |
Define the points on the surface.
The angle is computed between the Z compass direction and the normal
to the surface.
The computed angle remains constant at any selected point on that
particular
highlight line.

|
 |
You can right-click a line to convert it into a curve. Two
options are available from the contextual menu:
-
Keep this
highlight line
-
Keep all
highlight lines
The created curve(s)
appears in the specification tree as a datum element. |
| |

|
|
-
Depending on the highlight type selected, do the
following:
- By Angle: Key in an angle, representing the value between the
selected direction and the normal or tangent to the surface.
- By Point: Specify the points on the surface.
|
|
|
-
Click OK when you have finished the analysis.
The analysis (identified as Highlight Lines Analysis.x)
is added to the specification tree.
