First Steps with RFEM
QuestionWhat is the easiest way to define a polygonal surface graphically?
Basically there are two options:
- If no structural lines are defined yet, a polygonal surface can be defined by menu bar → "Insert" → "Model Data" → "Surfaces" → "Plane" → "Graphically" → "Polygon", see picture 1
- If structural lines are already defined, a polygonal surface can be defined by menu bar → "Insert" → "Model Data" → "Surfaces" → "Plane" → "Graphically" → "Select Boundary Lines", see picture 2
