Point and Curve Creation Overview | Statement List

Create Point

The Point statement creates a point using several different methods. You can enter the coordinates of a point (coordinates may be variables) or defined points relative to existing geometry (e.g. the center of a circle).

You may also find it quite helpful to define points using subscripted names in an array (e.g. P(1), P(2), etc.). In this way you can, in most instances, use the array to define the entire series of points in other GRIP statements.

For example, if you declare an object array: P(2), and define points, P(1) and P(2), you can define a line as being created at P. See the following example.

ENTITY/P(2),L1
P(1)=POINT/0,0
P(2)=POINT/1,0
L1 =LINE/P

The line, L1 is created from P(1) to P(2). You could also delete the points by specifying the array.
