#### Parameter definition

VariableDescription
entype Entity type
options: P, PS
enid Entity ID
nid${}_{seed}$ Seed node id, marking material to keep after trimming
$t_{trim}$ Trim time
$\hat{x}$ X-component of trimline projection direction
$\hat{y}$ Y-component of trimline projection direction
$\hat{z}$ Z-component of trimline projection direction
$x_1$ X-coordinate of trim line point 1
$y_1$ Y-coordinate of trim line point 1

#### Description

Trimming function for metal stamping applications. The trim path is a discretized line, defined by a list of coordinates.

#### Example

Trim 1

The following command defines a trimming operation on part 4 at time 0.2. The seed node 88460 marks the material to keep after trimming. The trim line is projected on the metal sheet in the z-direction.

*TRIM
P, 4, 88460, 0.2, 0.0, 0.0, 1.0
-0.681E+03, -0.235E+03, 0.468E+02
.
-0.683E+03, -0.249E+03, 0.371E+02
Trim 2

For lancing operation where there is no scrap material, the seed node is to be omitted. The example below is a lancing operation on part 3 at time 0.01. The cutting line is projected on the metal sheet in the z-direction.

*TRIM
P, 3, 0, 0.01, 0.0, 0.0, 1.0
-13.6, 10.2, 0.0
10.3, -12.2, 0.0
