C# Class Revit.SDK.Samples.NewHostedSweep.CS.EdgeFetchForm

This form is intent to fetch edges for hosted sweep creation or modification. It contains a picture box for geometry preview and a tree view to list all the edges which hosted sweep can be created on. If the user mouse-over an edge where a hosted sweep can be created, the edge will be highlighted in yellow. If user clicks on the highlighted edge, the edge will be marked as selected in red color. Click it again to un-select, the color will turn back. Edge selection from preview box will be reflected in edge list and vice versa. The geometry displayed in the picture box can be rotated with left mouse or arrow keys (up, down, left and right) and zoomed with right mouse.
