Since selection are so closely related, and use many of the same
functions, they are presented together. The major difference is that
the selection menu offers the select connected, while deselection does
not offer a deselect connected.
====================================================================
Select and Deselect: All Vertex Page 2-2
Function: Select All
FastKey: S-A
Description:
This will select every vertex currently in memory. You may notice that
the information strip has the line SLCT:. This is the total number of
selected vertices. After this function returns, this number should
match the VERTS: line at the top of the information strip.
====================================================================
Function: Deselect All
FastKey: D-A
Description:
This will deselect every vertex currently in memory.
====================================================================
Select and Deselect: Swap Vertex Page 2-3
Function: Select Swap
FastKey: S-S
Description:
This will swap the selection of every vertex currently in memory. If
the vertex was selected, it will be deselected, and vice-versa.
====================================================================
Function: Deselect Swap
FastKey: D-S
Description:
This will swap the selection of every vertex currently in memory. If
the vertex was selected, it will be deselected, and vice-versa.
====================================================================
Select and Deselect: Named Vertex Page 2-4
Function: Select Named
FastKey: S-N
Description:
This function will bring up a menu of all names currently in memoory.
You can choose any object name you wish by clicking on it. Use the
arrow buttons to scroll the display. Drag select is supported.
Choosing cancel will cause your selections to be ignored.
Vertex now supports up to 255 seperate named objects.
====================================================================
Function: Deselect Named
FastKey: D-N
Description:
This function will bring up a menu of all names currently in memoory.
You can choose any object name you wish by clicking on it. Use the
arrow buttons to scroll the display. Drag select is supported.
Choosing cancel will cause your selections to be ignored.
Please note that objects are actually assigned a number. Therefore, if
you have an 2 objects, both named "LightBulb", these are actually 2
seperate objects - the name LightBulb will show up twice in the object
name list. To ensure they are all the same object with the same name,
then select both, and use the Name Selected option under the Modify
Menu.
Vertex now supports up to 255 seperate named objects.
====================================================================
Select and Deselect: Vertices Vertex Page 2-5
Function: Select Vertex
FastKey: S-V
Description:
This function will give you the pick pointer so you can select
individual vertices from the main view window. Exit the function by
pressing the right mouse button or the space bar. You may wish to
rotate the view before choosing this function. Select Vertex and
Select Area now work the same - you can either click on a vertex OR
draw out a box while using either function.
====================================================================
Function: Deselect Vertex
FastKey: D-V
Description:
This function will give you the pick pointer so you can deselect
individual vertices from the main view window. Exit the function by
pressing the right mouse button.
Also, you may alter the view, while in either of these functions by
pressing the associated button to the left. You may not, however,
rotate, position or scale the view while in using these functions.
====================================================================
Select and Deselect: Area Vertex Page 2-6
Function: Select By Area
FastKey: S-R
Description:
This function will give you the pick pointer so you can select
vertices by dragging out a rectangle. Press and hold the left mouse
button to size the rectangle. Exit the function by pressing the
right mouse button. You may wish to rotate the view before choosing
this function.
====================================================================
Function: Deselect By Area
FastKey: D-R
Description:
This function will give you the pick pointer so you can deselect
vertices by dragging out a rectangle. Exit the function by pressing the
right mouse button.
Also, you may alter the view, while in this function, by pressing the
associated button to the left. You may not, however, rotate, position
or scale the view while in this function.
====================================================================
Select and Deselect: Pattern Vertex Page 2-7
Function: Deselect Pattern / Select Pattern
FastKey: D-P S-P
Description:
Selecting vertices by pattern requires entering a selection pattern.
The pattern corresponds to how the vertices are layed out in memory.
Here is an example:
10 Vertices before selection:
(1 means selected, 0 means deselected)
1 1 1 1 1 1 1 1 1 1
After applying the selection pattern '1100' the 10 vertices are
selected as such:
1 1 0 0 1 1 0 0 1 1
The selection pattern is repeated until the last vertex is reached.
Pattern selection is a tricky function. It is not straight forward -
it depends on the order of vertices in memory. Normally, when a lathe
or grid is created, the vertices are added 1 at a time in order of
creation. Some functions in Vertex will change the order of the
vertices in memory. If you plan on using pattern deselection, do not
use it after these functions:
fuse
Subdivide Edges
Subdivide Faces
Delete Selected Vertices
These functions will mess-up the order of vertices in memory. You can
use pattern deselection after using these functions, but it will not
work very well.
====================================================================
Select and Deselect: Except Vertex Page 2-8
Function: Select Except
FastKey: S-X
Description:
This function will select every object except the one you choose. This
is a handy function that saves a lot of work when you need it.
====================================================================
Function: Deselect Except
FastKey: D-X
Description:
This function will deselect every object except the one you choose.
This is a handy function that saves a lot of work when you need it.
Suppose you have 10 objects in memory, and you have half of the
vertices of one object selected. Now, if you want to swap-select the
other vertices in that same object, you could choose Select-Swap. But
doing so will cause ALL vertices to be swapped. Now you must go through
by hand and deselect the unwanted vertices. This function eliminates
the need for this kind of work. Together with Select All Except,
you can have finer control over what gets selected and what doesn't.
====================================================================
Select: Connected Vertex Page 2-9
Function: Select Connected
FastKey: S-C
Description:
This function will select every vertex which is connected by edges
to a selected vertex. This is useful when objects overlap, and you
can't select the object you want.
====================================================================
Select: Exterior Edges
Function: Select Exterior Edges
FastKey: S-E
Description:
You'll probably want to do a Deselect-All before using this function.
It will select every vertex which is part of an exterior edge. An
exterior edge is one which is part of only 1 face.
Please note, this function is not very fast. Small objects will get
selected fairly fast, but as more edges are added, the time this
function requires will grow exponentially! Don't be surprised at a 5
minute wait for objects with 3000+ edges. You can now abort this
function by pressing any key.
This is probably a useless function to use on a grid type object, or
something similar. I developed it while working on a plant object. I
wanted to select the edges of all my leaves and move them down the Y
axis. Doing this by hand would of taken a long time, so I wrote this
function to do it for me.
====================================================================
Select: Layer
Function: Select Layer
FastKey: S-L
Description:
A requester appears asking for the Low and High coordinates for each axis.
Entering a value of zero for an axis will cause the entire axis to be
within the box. For example:
Low X: 0
High X: 0
Low Y: -10
High Y: 10
Low Z: 0
High Z: 0
This will cause all vertices with Y coordinates between -10 and 10 to
be selected. The zeros for the X and Z axes tell Vertex to use the entire
range for that axis.
====================================================================
Select: Shrink Vertex Page 2-10
Function: Select Shrink
FastKey: S-K
Description:
This command will deselect every point which is connected to a selected
vertex.
====================================================================
Select: Expand
Function: Select Expand
FastKey: S-D
Description:
This command will select each point which is connected to a selected
point. The net effect is that the area of selected points will expand.
