Modifying 2D elements from linear to quadratic

Linear 2D elements (i.e. Tri3 and Quad4) can be converted to quadratic (i.e. Tri6 and Quad8, respectively) using the Sculpt > 2D element operations > Modify linear 2D to Quadratic menu command. The procedure is as follows.

1. Set the cursor mode to Select elements.
2. Select the 2D elements that are to be converted.
3. Give the Modify linear 2D to quadratic command.
