Point Editing

The Point Edit Tools allow you to select and modify points, edges, & faces; and groups of points, edges, & faces.
Point Edit:	The Point Edit menu allows you to edit selected points on the object. The available tools are Context, Faces, Edges, Vertices, and Delete Face. Selecting any of these tools changes the cursor by adding a small 'P' to the lower right edge of the cursor.
Context:	Selecting Point Edit: Context allows you to select any face, edge, or vertex depending on where you click on the object.
Faces:	Selecting Point Edit: Faces allows you to select any face on the object, but not vertices or edges. Faces are selected by clicking anywhere on a face.
Shift-clicking on two or more faces selects those faces, whether they are concurrent or non-concurrent faces: Ctrl-clicking will only select non-concurrent faces. If you try to ctrl-click on one of the faces or edges between two already selected faces, it won't happen. You'll have to use shift-click to select that face.
Another example of shift- or ctrl-clicking on non-concurrent faces. Rotate the object to select faces on the other side of the object, or the top and bottom faces.
An example of using ctrl-click to select non-concurrent faces and edges. If you try to select any face or edge in between any of the selected faces, nothing happens. Again, use shift-click to select the face in between the two already selected faces
Edges:	Selecting Point Edit: Edges allows you to select any edge on the object, but not faces and vertices. Edges are selected by clicking directly on the edge.
Shift-clicking on two concurrent edges also selects the joining edges: For example, if you select the left edge, then shift-click on the right edge, the top and bottom connecting edges are also selected. If you select the top edge, then shift-click the bottom edge, then the right and left connecting edges will also be selected.
Ctrl-clicking on two edges only selects those edges: You cannot select the top and bottom edges, so if you want them, either use the select face tool or use shift-click to select two opposite edges as shown in the row above.
You can continue to select edges by using ctrl-click as long as those edges are not joining an edge that is already selected:
and more:
Selecting an edge and then shift-clicking on a non-concurrent edge creates a new edge between the two selected edges:
Shift-clicking on the top face of the object, selects everything except the edges in between the two edges selected above.
If you click on an edge, then ctrl-click on a non-concurrent edge, and then shift-click on an edge in between, then the connecting edges between that edge and the last selected edge are also selected.
Vertices:	Selecting Point Edit: Vertices allows you to select vertices, or points, on the object, but not faces or edges. Vertices are selected by clicking directly on any vertex (point) of the object.
Multiple vertices can be selected by using either shift-click or ctrl-click while selecting. Shift-clicking on two concurrent vertices selects both verices and the joining edge:
Shift-clicking on a third vertex anywhere on the same face selects the entire face:
Shift-clicking on a third vertex anywhere on a different face selects that vertex, plus the matching vertex on the other side: Of course, this also creates new edges between the selected vertices creating some interesting results when manipulating the vertices.
Shift-clicking on a third vertex anywhere on a different face, but farther away, not only selects the vertex and its matching vertex, but also selects vertices on the edges between: Again, this also creates new faces between the selected vertices creating some even more interesting results. The farther away the third selected vertex is from the first two vertices, the more "interesting" the results will be.
Ctrl-clicking on concurrent vertices selects just those vertices:
Ctrl-clicking on non-concurrent vertices also selects just those vertices:
You can also select vertices on different faces with ctrl-click and it will still only select those vertices:
You can also ctrl-click on two or more non-concurrent vertices and then shift-click on another vertex: Again, a new edge is created between the two vertices where the shift-click is used.
Delete Face:	Selecting Point Edit: Delete Face changes the cursor by adding a small 'P' to the lower right edge of the cursor and a small grey box on the arrow. Once selected, click on any face of the object to delete that face.
Point Edit:	When you left-click on the selected Context Edit tool, the point edit panel comes up.
The Draw attribute determines how the object is redrawn after editing. The default is Object which redraws the entire object as the selected items are modified. Left-click on the button to access the pull-down menu to select Edited, which will only redraw the selected items that have been manipulated. If working with complex objects, select Edited.
Dynamic Subdivision determines how tS2 subdivides polygons that become nonplanar during point editing. According to the help file, "This tool is available because some editing operations may cause a loss of planarity in polygons with more than three vertices. If you notice rendering errors, you could try to break these polygons that may have become non-planar down into smaller planar triangles or quadrangles by choosing the Quadrangles or Triangles option." No DynDiv is selected by default. The Quadrangles and Triangles selection doesn't work with all objects. On some objects, the selected items will snap back into place while creating the new faces or the program will close.
Quadrangles:	Using the default setting of 0.1:
	and setting of 1.0 (the highest allowed):
Triangles:	Changing the setting for this one doesn't seem to make a difference in how many triangles are created. Only one new triangular face is created per edge.
Point Navigation:	When you select one of the point edit tools, the point navigation panel pops up. From this panel, you can modify the selected vertices, edges, or faces by moving, rotating, or scaling it; and by slicing or separating it. The Slice button is selected by default, but both the Slice and Separate buttons are deselected automatically when you select a face, edge, or vertex.
Point Move:	Moves the selected vertices, edges, or faces along the x-, y-, and/or z-axis depending on the axes.
Point Rotate:	Rotates the selected vertices, edges, or faces along the x-, y-, and/or z-axis depending on the axes selected.
Point Scale:	Scales the selected vertices, edges, or faces along the x-, y-, and/or z-axis depending on the axes selected.
	To select the axes along which to move, rotate, or scale the selected vertices, edges, and faces, right-click on any of the point navigation tools that have a small red triangle in the top right corner of the button. See the Moving & Resizing page on how to use this panel.
Slice:	Slice object by selected line/plane does just that, by creating a new face or edge.
	Select the Point tool you wish to use, then select the face, edge, or vertex. With the item selected, left-click on the Slice button. The selected item will go white, but just left-click on top of it and it will be selected again.
	Next, press and hold the left mouse button and drag your mouse in any direction. The selected face will expand, creating new edges and vertexes as it goes.
	Now, select the point navigation tool that you want to use from the point navigation panel. Use either the left or right button and either move, rotate, or scale the selected item.
Face move:
Side view:
Face Rotate:
Face Scale:
And to be fair, selecting a face on a cylinder and slicing it does this:
While selecting an edge and slicing it does this:
But selecting the top or bottom face of a cylinder or cone does this:
Separate:	Separate selected part of object duplicates the selected item and separates it from the original object.
	First, select the Point tool you wish to use, then select the face, edge, or vertex. With the item selected, left-click on the Slice button. The selected item will go white, but just left-click on top of it and it will be selected again.
	Left-click hold on the selected item and drag it off the original object.
And that's it for the Point Edit tools, let's move on to Sweeping now that we can select faces.
