No, load generation, such as "Surface Load on Members via Plane", only works for straight or articulated straight members.
If necessary, curved members can be converted into polygonal members as follows:
- Divide the curved member by the desired number of intermediate nodes (right-click the member → Divide Member).
- Select all curved members.
- In the table, change the line type from "Arc" to "Polyline".
- If necessary, use the "Show Selected Objects Only" function; see Image 01.
- Change the top line type in the table.
- Select all rows → right-click → "Set", see Image 02.
- Generate Loads
