Selecting Polygons

When in Edit mode, Polygons can be selected by clicking on individual facet or by dragging a selection rectangle.

Splitting Polygons

Selected Facets can be split up into further facets. Triangles are subdivided into three further triangular facets and quadrilaterals are subdivided into two further quadrilaterals. The split is invoked by selecting the Split Polygons item on the right click menu, (Right-Click -> Polygon List -> Split Polygons) or by pressing Ctrl+K.

Merging Polygons

Individual facets can be merged if they share an edge. Select two neighbouring facets and select Merge Polygons from the right click menu, (Right-Click -> Polygon List -> Merge Polygons) or press Ctrl+M.

Deleting Polygons

Individual facets can be deleted by pressing the Delete.
