Editing tools that create multipatch and 3D object feature geometry automatically snap to the geometry you are actively drawing. When you hover near a snappable 3D geometric element, an orange snap agent symbol appears with the pointer, and edge extensions appear as orange dashed lines.
Multipatch and 3D object feature snapping is described in the following table:
Global axis or line extension Snap to the global axis or line extension. |  |
Vertex Snap to the vertex of existing geometry. |  |
Intersection Snap to the inferred intersection. |  |
90 degree Constrain the new segment 90-degrees to the previous segment. |  |
Parallel Constrain a new segment parallel to existing geometry. |  |
Midpoint Snap to the midpoint of existing geometry. |  |
