DP Card
The DP card is used to define points in space. These points are used to define the extent and orientation of other geometric entities and to locate excitations.
On the Home tab, in the Define group, click
the Point (DP) icon.

To avoid ambiguity each point is assigned a name (a 5 character string if column based format is used.) In other cards (for example the BL card) the points are referred to by their names.
Parameters:
- Point name
- Name of the point.
- X 座標
- X 座標 of the point in m (is scaled by the SF card).
- Y 座標
- Y 座標 of the point in m (is scaled by the SF card).
- Z 座標
- Z 座標 of the point in m (is scaled by the SF card).
- Nurb control point weight
- The weight of the control point when this point is used with the NU card (NURBS surfaces). If the field is empty, it defaults to 1.
Examples of DP Card Usage
[node!variable name]
For instance, it would now be possible to
define the points P1 to P20 inside a loop.!!for #k = 1 to 20
DP: P#k

Unlike most other geometry cards, the DP card (as well as the TP card) may also be used in the control section (after the EG card) of the .pre file. This allows defining the points required by the AP card in this part of the file.
