In some AREAL3D-tools elements can be drawn connected one after each other.
Workflow:
- Draw the first fence
- Hover the fence at the desired end. It will be selected.
- Left-click at the fence near the selected end
- Areal retrieves the original drawing point of the fence and starts a new fence.
Surely this does not generate a continuous geometry, but can make working easier in many situations and very often (especially for distant views) it is sufficient.
Where really necessary, the geometry can be edited afterwards.
We are working on a continuous input at the moment for polygonal elements. But it takes some time....
