Available Derived P-points for Hull Models - Symbolic Representation
- Last UpdatedAug 13, 2025
- 3 minute read
Derived p-points are implemented for some hull models when they are drawn with symbolic representation. In symbolic representation, the set of derived p-points is dependent on the projection type:
Planar projection, showing an outline of the model, for example, a plate, or a clip.
|
Outline of plate |
Outline of clip |
|---|---|
|
|

Intersection projection, showing a cross section view of the model, for example, a plate <pict> or stiffener. Please note that a stiffener has two types of intersection projection:
-
top view which displays the profile trace
-
cross section view.
Intersection projection of stiffener, top view
Intersection projection of stiffener, cross section view
