Moving Solids/Surfaces with the Select Tool Examples
When you hover and pre-highlight a vertex, the curve to which it belongs is
highlighted. Using the mouse wheel, you can scroll through other curves attached to
the vertex.
When the curve you want is highlighted, you can Alt-drag to move only the vertex of
that curve.
Pressing the Alt key changes the Move cursor to the Detach-and-Move cursor.
You do not need to hold the Alt key throughout dragging. You can release it once you
start dragging.
In the images above, notice the "source-generated dotted lines" extending from the
other curve. This is similar to the behavior in Sketch Mode for aligning and
snapping the vertex. By default, the system generates them extending from all curves
that intersect at the selected-and-moving vertex.
When you hover over any straight line or edge while dragging a vertex, a dotted
vector will be generated. This allows you to snap to the extension of any existing
line or edge.
Sub-curve midpoints are available for snapping if you Shift-hover over the parent
curve.
