After adding a trim operation to your analysis, you can define trim, pierce and lance
lines.
Add lance lines after you have completed all required trim
stages. The software cannot trim parts that are lanced.
Select a Trim operation that you added to your analysis.
The Trim, Pierce, and Lance tools appear on the Tryout ribbon.
Note: If your model includes a single trim line, the software automatically
identifies it. If more than one trim line exists, the longer line is
identified as a trim line and the remaining lines are identified as pierce
lines.
Select the Trim, Pierce, or
Lance tool.
On the model, select the line(s) or edge(s) where you want to create the trim,
pierce or lance line.
Click to confirm or on the guide bar, click
Assign.
The trim, pierce and lance lines are assigned. An arrow appears for each
line indicating a direction for the trimming process. The default direction is
based on the average normal.Figure 1. Model with Trim and Pierce Lines Figure 2. Model with Lance Line
