Hello,

The **Linear Cell Extrusion** filter would be able to extrude triangles into prism elements. However, this filter requires that the data be Cell data.

If this filter is not available, you will need to write an extrusion script with a **Programmable Filter**. The following may be helpful in this case.

This has no effect on the 3d view. It only changes the width of the line in the cross section. However, the larger line thickness l…
