A vector defines a direction and is not bound to any position.
representation of vectors:
- vectors are only temporarily displayed,
- Always in the center of the picture.
- Normalized vectors (with length 1) in black, otherwise red.
The following are standard vectors:
DX DY DZ
according to standard axis directions;
DIX DIY DIZ
correspond to the inverse standard axis directions
Definition of a vector by:
- select a line or a circle (normal vector)
or a plane (normal vector) or by 2 points
- Selection of a vector by Page Up/Page Down (picture) keys
- enter a standard vector (with the keyboard:)
DX or DY or DZ or inverse to DIX DIY DIZ
- entering a vector (with the keyboard):
defined by entering a vector, for example, "D12"
by the X / Y / Z-components, "0,0,1" defines a Z-vector
by one or two angles (rotateangle, tiltangle)
The last parameter may be "REV" (vector is shown reverse).
As the penultimate parameter the vector length can be specified.
Example: "DX 2" or "DX 2 REV"
For example:
# vector 1 = direction negative X-axis
D1 = DIX
# 2 = vector in direction x = 1, y = 1 in the XY plane
D2 = D(1 1 0)
vector from copyfunction
These formats are generated from selection functions:
# vector of line:

# vector of polygon segment
# or vector of line in a CCV:
D ((obj) MOD ((segment number)))
# vector of line in a vector CCV
# or polygon segment in a CCV:
P ((obj) MOD({CCV-segment number}) MOD({segment-number}))
Example: # vector from 1.segment the CCV S26 (one line):
P (S26 MOD(1))

B# = TOR C C // main_circle, outer_circle
B# = TOR R C // mani_radius, outer_circle
The axis of the circle of skin is the main axis.
The minor circle axis is always normal to the main axis.
Radius_major circle is entirely on the outside, and is always positive.
Modifier_outer_Inner: required for selection of a variant
where the Radius_major circle is smaller than the Radius_minor circle.

Notes / Dimensions
Identification letter for Notes/Dimensions is N.
____________________________________________________________________________
see also CAD-Functions for Notes / Dimensions
The font size for text and dimensioning is defined by
DEFTX {Textsize} {DimTextSiz} {text general scale} {number decimal places}
or interactively in Standards/Text.
Default values in the file {base}/xa/gCAD3D.rc.
TODO:
TEXTS AND DIMENSIONS ARE NOT EXPORTED TO IGS or DXF.
For interactive modification of the parameters Marrow, Mline
and additional text a user interface is to be created.
____________________________________________________________________________
Model
Identification letter for Models is M.
____________________________________________________________________________
see also CAD-Functions for Models
A model (a Assembly) can consist of several Models (Sub-models)
____________________________________________________________________________
Transformations
Identification letter for Transformations is T.

Rotation
CW (clockwise) or
CCW (counter-clockwise)
The specification of CCW is not required (default).
The rotation results in plan view of the axis of rotation
as seen by the eye of the beholder.
Rotation angle (Rotate)
The rotation is around the Z-axis of the active construction plane.
Input directly: Angle
Enter indirectly: ANG(angle)
Output format: ANG(angle ()), for example:
ANG(30) - rotation by 30 degrees
# Angle value
ANG (angle value [REV])
# Direction vector
ANG (D [ANG () / REV])
# Line (direction)
ANG (L [ANG () / REV])
# 2 Points (direction)
ANG (P P [ANG () / REV])
In CAD mode, the PgUp / PgDown button can add together one additional (relative)
angle value of about +90 degrees. (There must have been a prior
selection to indicate direction (eg select a line)).
Tilt angle
The rotation (tilting) is done to the new Y-axis created by a rotation of the Z-axis.
A tilt angle of 90 degrees provides the Z-axis (independent from the angle of rotation).
Output format: ANG({angle}), for example:
ANG(30) - rotation by 30 degrees
Example of rotate and tilt:
ANG(90) ANG(30)
There the object is rotated 90 degrees around the Z axis;
The horizontal axis now corresponds to the old X-axis, tilt axis at this
tilt is now around 30 degrees.
A negative tilt angle rotates in the opposite direction.

Page: with PageUp / Down button;
1, 2 lateral right / left;
Output Format: MOD (1) or MOD (2)
Additional text with special characters
A special character is generated by a sequence of 2 characters.
[d diameter sign
[g degree sign (angle)
[+ + - Signs
[' double quote (")
[/ Superscript
[\ Subscript
[n new line (return, CR)
[% Is replaced by the standard text. If the text does not include [%,
the default text provided throughout is inserted.
[- no standard text.
[[ a square bracket "["
[0 to [9 only N=DIM3 and N=LDRP: Number of decimal places of the dimensions
(must be at the beginning of the text block)
[V20] to expand a numeric variable (V20 in the example)
Example:
“[+ 0.2 "
Dimension arrows
are defined by specifying a number with 2 digits;
one digit for each of the two dimension arrows;
No indication or -1: create both arrows automatically.
0 no dimension arrow;
1 < left arrow
2 > right arrow
3 / slash
4 > < arrow right and arrow left
Example:
"12" left arrow and right arrow
Extension lines
are defined by specifying a number with 2 digits;
one digit for each of the two extension lines;
0 = no guide,
1 = line
Default is 11 (two lines)
Color
0 = black
1 = DefCol
2 = red
3 = green
4 = blue
5 = yellow
6 = purple
7 = blue
8 = white
Symbolic file names:
A symbolic file name consists of
"{path}/{filename}"
All symbolic pathe are defined in file {base}xa/dir.lst.
The icon can be freely chosen.
Interactively define the path using the "Standards/Directories".
Default directory is {base}/dat; the identifier for this
directory is "Data".
Example of symbolic file name:
"Data/Niet1.dat"
____________________________________________________________________________
Group
Identification key for group is U.
____________________________________________________________________________
Select the objects in the group - the objects will be highlighted.
Remove from the group by selecting again.
Go to the next field with the Tab key.
Example:
# Group 2 surfaces
U (A20 A21)
____________________________________________________________________________
In the CAD input fields numerical values can be used (eg, for radius only) as well as variables,
PI, the basic arithmetic and mathematics. Functions are also used (but not the functions X, Y, Z and L, C).
