THE ADD MENU:

To add anything to Vertex, you must either read an object from disk,
or create a new object within the program. Object reading is covered
in its own section, later in this manual.
The Add menu is where you can create new objects. Available are
functins to create lathes, polygons, grids, simple shapes such as
rings and spheres, and individual vertices. Also included, are
functions to add specific edges and faces to previously created
objects.
====================================================================
Add Menu: Shapes Vertex 1-2
Function: Add Shapes
FastKey: A-S
Description:
This is the new polygon creator. Should be a vast improvement over
the older tool.
This function changes the main view into the shape definer. The
buttons on the left of the display will change:
POINTS Add points, connected by edges. Auto close on points.
LINES Click and drag. See below for resolution.
BOX Click and drag out a rectangle.
ARCS Click the CENTER point, drag out a line, press and
hold to define the arc (up to 180 degrees in either
direction.)
EDIT Lets you edit your shape while in the Shape Creator.
SET RES Adjust the resolution for lines and arcs, above.
GRID Toggle the grid on or off.
SNAP Toggle the snap-to-grid. Grid must be on to work.
GRID RES Set the grid resolution on X and Y
OVERLAY Draw all previous objects, from the front view,
behind your new shape and the grid.
EXIT Exit this tool.
The first function, POINTS, should operate just like the older
Add-Polygon tool, but the shape will auto close when you re-click on
a point. To start a new shape, simple re-select this option.
Lines and Arcs can have a settable resolution. The arcs may take some
getting used to - Just remember to first click at the CENTER of the
arc, then draw out the radius, then click and hold to sweep out the
arc itself. You can change the resolution by adjust Set-Res.
Edit will let you re-shape your objects immediately. There may be
screen residue after moving a few points - to get rid of it, just
click on EDIT again.
Grid will toggle the state of the grid. Snap has been seperated from
grid per user request.
You may choose exit at any time.
====================================================================
Add Menu: Grid Vertex Page 1-3
Function: Add Grid
Fast Key: A-G
Description:
Grids are similar to graph paper. You can define the width and height
of the grid, and the resolution.
When this function is chosen a requestor appears, asking for the
following information:
GRIDX: This is the size, in units, of the grid width.
GRIDY: This is the size, in units, of the grid height.
RESX: This is the number of divisions to use for the width.
RESY: This is the number of divisions to use for the height.
NAME: The name of the new object.
Grids are nice for applying curves to and using the multiply function
with. Be careful, however, as grids can take up large amounts of
storage space quickly.
Add grid now places the grid on the X,Y axis. Previous versions placed
the grid on the X,Z axis.
====================================================================
Add Menu: Duplicate Vertex Page 1-4
Function: Add Duplicate
FastKey: A-D
Description:
You can duplicate any object or set of selected vertices. You are
presented with a requestor asking for:
DISTX: This is the amount to move the new object on the X axis
DISTY: This is the amount to move the new object on the Y axis
DISTZ: This is the amount to move the new object on the Z axis
ROTX: Amount of rotation around the X axis
ROTY: Amount of rotation around the Y axis
ROTZ: Amount of rotation around the Z axis
SCAL X: Amount of scaling on the X axis
SCAL Y: Amount of scaling on the Y axis
SCAL Z: Amount of scaling on the Z axis
STEPS The number of diplicates to create. This value is divided
into the DIST, ROT and SCAL amounts you enter.
This requester is getting a little crowded. You can now move, scale
and rotate the duplicate parts, and set the number of steps to take
in the duplication.
All selected vertices, and any associated edges and faces will be
duplicated.
====================================================================
Add Menu: Basic Shapes Vertex Page 1-5
Function: Add Basic Shapes
FastKey: A-B
Cube A-B-C
Pointed Star A-B-P
Ring A-B-R
Sphere A-B-S
Tube A-B-T
Cone A-B-N
Disk A-B-D
Circle A-B-C
Arc A-B-A
File A-B-F
Cube
When this function is selected a requestor appears asking for the
length, with an height of the cube to be created, and its name.
Pointed Star
You are prompted with a reqiestor asking for the number of Points,
the total diameter, and the name of the object.
Ring
This function brings up a requestor asking for a number of values:
Radius1 The actual diameter of ring sections
Radius2 The total diameter of the finished ring
Points The number of points to create ring sections with
Res The total number of divisions to make in the entire
ring
Name The name of the object.
Sphere
The add basic sphere function askes for the diameter, points and
res of the sphere.
Radius The total width of the finished sphere
Points How many points to make the side of the sphere
Res The total divisions to create the sphere
====================================================================
Add Menu: Basic Shapes Vertex Page 1-6
Tube
You enter the the radius, height and resolution.
Cone
Similar to tube, but creates a solid base object.
Disk
Enter radius and resolution.
Arc
Lets you easily add arcs with any radius,resolution and degrees.
Circle
Enter the radius and the resolution.
File
I've included this so we can easily define a set of objects and
have them available without hunting through directories. To use
this feature you must take care of some pre-requisites:
1. The ENV: device must be available. If you do not have an
ENV: device, I'd suggest adding this line to your
startup-sequence:
assign ENV: ram:
2. There should be an entry on the ENV: device called PRIMS.
You can create this file thus:
setenv PRIMS dh0:3d/objects/primitives/
Or use any directory you wish. Again, I'd suggest you put
this line in your startup-sequence.
If you've set everything up properly, you can access this
directory anytime you choose this menu option. After Double
clicking the file you wish to load, a requester will appear
asking for 3 scaling values, X,Y and Z. This lets you easily
scale the objects at load time.
I've had at least one request for this type of feature. If you think
it's worthless, then don't bother with it. However, if you do
something like set-design and you need a set of basic shapes to
be used over and over, you just save them here and have them
available quickly and easily. The directory is cached, meaning
when you go to save your actual file, the original directory will
still be in the file requester.
====================================================================
Add Menu: Vertex Precise Vertex Page 1-7
Function: Add Vertex Precise
FastKey: A-V
Description:
You can add vertices at precise positions with this function. You are
presented with a requestor asking for:
POSX: The X coordinate of the vertex
POSY: The Y coordinate of the vertex
POSZ: The Z coordinate of the vertex
The name of this vertex will be the name of the last vertex. If you
wish to enter large numbers of vertices in this manner, you may want to
use Arexx instead.
====================================================================
Add Menu: Edge Vertex Page 1-8
Function: Add Edge
FastKey: A-E
Description:
This function lets you add edges by clicking on 2 vertices.
You can continue adding edges until you press the right mouse button.
If you create an edge over an existing edge, it will be deleted by
Vertex.
====================================================================
Add Menu: Add Face
Function: Add Face
FastKey: A-F
Description:
This function lets you add faces by consecutively selecting 3 vertices.
You can continue adding faces until you press the right mouse button
or the space bar.
If you create an edge over an existing edge, it will be deleted by
Vertex.
This function is the only good way to fill concave polygons. If you
create a polygon you may try filling it with Planar-Fill under
modify. If this does not yield correct results, you may either add the
faces by hand, or use another software which has the ability to fill
concave polygons.
