Creating and Manipulating Drafting Primitives

An ARC can be defined in three ways:


PTFA	-	Point references (3)
NLSTYLE	-	Note line style
NLCOLOUR	-	Note line colour
RADI	-	Radius
ASUB	-	Angle subtended
TCOD	-	Type code (defines how to interpret attributes). Either set to ENDPOINT or CENTRE.

Basic Creation Method

•

by defining the positions of the end-points and a ‘through’ point (from which the values of Radius (RADI) and Angle Subtended (ASUB) can be derived if required).

•

by defining the position of the centre point, ‘from’ point and Angle Subtended (from which the position of the ‘to’ points and the value of RADI can be derived if required).

•

by defining the position of the centre point and two end points.

The method:

NEW ARC
DEF @

results in three points being prompted for (the ‘start’, ‘end’ and ‘through’ points). A line is drawn through the points and TCOD is set to ENDPOINT. Refer to Positioning (absolute) (of an arc point) for further information. If used with an existing ARC any existing values of RADI and ASUB are altered accordingly.

Defining or redefining an Arc with a centre- and two endpoints is achieved using the command:

ADEFine <dfnpt> <dfnpt> <dfnpt>

where <dfnpt> defines a position (2D, 3D, p-point etc).

The first two points are the centre - (CPT) and ‘from’ point (FPT) of the Arc. These two points define the radius. The third point defines the angle subtended by the arc. The TO-point (TPT) lies in this direction from the Centre (CPT) at the same distance as the FPT from the CPT. The TCOD attribute is set to CENTRE.

This command may also be used with the cursor:

ADEFine @

A prompt requests three 2D points to be input for CPT, FPT and angle subtended. 3D points may also be input using the cursor:

ADEFine ID@ ID@ ID@
DEFine IDP@ IDP@ IDP@

Changing Radius and Angle Subtended

RADIUS value [DESIGN]

Sets RADI. For TCOD CENT this moves the ‘from’ and ‘to’ points radially (by the change in the value of the radius). Centre point position and ASUB are not altered. For TCOD ENDP this moves the ‘through’ point and changes ASUB; the positions of ‘from’ and ‘to’ points are unchanged.

RADIUS X value Y value
RADIUS E value N value U value
RADIUS IDP @
etc.

For TCOD ENDP this is like THPT @.

ASUBTENDED value [ANTICLOCKWISE]
ASUBTENDED value CLOCKWISE

Sets ASUB. (A positive angle is anticlockwise, a negative one clockwise.)

For TCOD ENDP this repositions the ‘through’ point (mid-way along the Arc) and changes RADI; ‘from’ and ‘to’ point positions are unaltered. For TCOD CENT this moves the ‘to’ point of the arc. Centre and ‘from’ points and radius are unchanged.

ASUBTENDED CLOCKWISE
ASUBTENDED ANTICLOCKWISE

Sets the value of ASUB to be negative or positive, respectively.

ASUBTENDED @

For TCOD ENDP this is like THPT @; For TCOD CENT this alters the angle subtended and hence moves the ‘to’ point of the Arc. The new position of the ‘to’ point lies on the line joining the centre-point and the cursor position; centre and ‘from’ points and radius are unaltered.

Positioning (absolute) (of an arc point)

The syntax is similar to that for FPTs of STRAs. Possible points are CPT (centre point), FPT (‘from’ point), TPT (‘to’ point) and THPT (‘through’ point).

CPT @
etc.

This changes the arc to be one with TCOD CENT (if not already so). The Centre is moved whilst keeping the ‘from’ point and ASUB unaltered. The ‘to’-point and radius are recalculated.

THPT @
etc.

This changes the Arc to be one with TCOD ENDP (if not already so). The position of the ‘through’ point is moved whilst keeping the ‘from’ and ‘to’ points fixed - i.e. both radius and angle subtended are altered.

FPT @
TPT @
etc.

For arcs with TCOD ENDP, the ‘from’ or ‘to’ point of the Arc (as appropriate) is moved whilst maintaining the positions of the other end point and the ‘through’ point.

For Arcs with TCOD CENTRE, the ‘from’ or ‘to’ point of the Arc (as appropriate) is moved whilst maintaining the position of the centre and the angle subtended. Thus the radius may change and the position of the other end point will be moved to preserve the angle subtended.

Repeated Copying

Refer to CIRCLE (CIRC) for further information.

Dragging another primitive to which the Arc is connected

During the course of a DRAG operation on another primitive, the points of the Arc may move. The effect on the Arc is as follows.

•

for arcs with TCOD ENDP, Radius and Angle subtended are changed.

•

for Arcs with TCOD CENT, if the centre point is dragged, then the positions of the ‘from’ and ‘to’ points are also moved to preserve the Arc’s appearance.

•

For Arcs with TCOD CENT, if an end point is dragged, then a rotation about the other endpoint takes place, i.e. the centre point is moved and the radius changed.

Note:

If used with an existing Circle the DEF command always sets ADEG=0 and ORIG=CENTRE

Identification

ID CIRC @

This method applies to all primitives described below, for example ID ELLI @ (ellipse), ID RECT @ (rectangle) etc.

If DESIGN specified and if underneath a VIEW from which a scale can be obtained, a scaled circle will be drawn and the diameter stored in the database as a Design value.

OUTLINE (OUTL) and VERTEX (VRTX)

An Outline consists of a user-defined series of connected straight lines and circular arcs (collectively known as spans). OUTL elements do not have any geometry or positional data themselves, because they are of indeterminate complexity. This is provided by a list of owned Vertex (VRTX) elements. The origin of an OUTL is considered to be at the position of its first VRTX. As an alternative to straight lines and circular arcs, a smooth quadratic curve may be drawn through the vertex points of the OUTL (refer to CURFIT for further information).

A chamfer may be applied between two VRTXs using

(OUTL)


NLSTYLE	-	Note line style
NLCOLOUR	-	Note line colour
FSTYLE	-	Fill style (used to hatch the area enclosed by the OUTL)
FCOLOUR	-	Fill colour
MSTYLE	-	Marker style
MCOLOUR	-	Marker colour
CURFIT	-	Curve fitting control

Setting CURFIT to CUBICFIT will cause a smooth quadratic curve (which approximates a series of cubic curves) to be drawn through the vertex points of the OUTL. CURFIT DEFAULT turns off the curve-fit function.

(VRTX)


PTRF	-	Point reference
BULG	-	Bulge factor
NLSTYLE	-	Note line style	(Can override settings at OUTL)
NLCOLOUR		Not in colour
MSTYLE	-	Marker style
MCOLOUR	-	Marker colour
CHAM	-	Chamfer distances
FRAD	-	Fillet radius

Bulge Factor

The BULG attribute is unique to the VRTX element, and is the ratio of the maximum departure of the arc from the chord joining two VRTXs to the chord half-length. It is positive when the span lies to the right of the chord when viewed in the direction VRTX1 to VRTX2, negative when it lies to the left. A straight span has a BULG of 0, a counter-clockwise semicircle a BULG of 1.0, and a clockwise semicircle a BULG of -1.0. BULG would not normally be set explicitly, but indirectly by the SPAN command.

Chamfering

CHAMFER value [value]

The value(s) supplied in the above syntax must be greater than or equal to 0. If two values are supplied then the first chamfer distance will correspond to the chamfer joining the current VRTX to the previous one, and the second will correspond to the chamfer joining the current VRTX to the next. If only one chamfer distance is supplied, then both chamfer distances will be set equal. Setting the chamfer distance to 0 is equivalent to setting it to OFF. If the chamfer distance is set on a VRTX then the spans on either side of it will be drawn straight, i.e. the BULG attribute of the current and next VRTX will be ignored. CHAMFER OFF will remove the chamfer.

Filleting

A fillet may be applied to a VRTX using

FRADIUS value

Any value may be supplied in the above syntax. A positive value will correspond to a convex fillet radius at the VRTX, a negative value to a concave fillet. Setting FRAD to 0 is equivalent to setting it to OFF. If the fillet radius is set on a VRTX then the spans on either side of it will be drawn straight, i.e. the BULG attribute of the current and next VRTX will be ignored.

VRTX Basic Creation Method

The OUTL and VRTX elements may be created and deleted in the usual manner, e.g.

NEW OUTLine
NEW VRTX AT @
DELETE VRTX

The position of a VRTX and the shape of the span drawn to it from the previous VRTX are defined by the SPAN command. This command is valid at any VRTX except the first in list order. Variations of the SPAN command are:

SPAN TO position

Vertex point defined by <position>

SPAN THROUGH position

Span defined as a circular arc passing through position. Defines BULG.


	SPAN TO position THROUGH position	Above two commands combined. Also SPAN @
	SPAN THROUGH position TO position	Above two commands combined. Also SPAN @

SPAN TO CLOSE

Vertex point coincident with starting vertex.

SPAN STRAIGHT TO position

Straight line span with vertex at <position>

SPAN RADIUS value

Set radius of circle of which (arc) span forms a part. Converts straight line span to an arc.

SPAN ASUB value

Sets angle subtended by (arc) span. Converts straight line span to an arc.

SPAN BY xypos

Move the two VRTXS of the current span by the given displacements.

SPAN DRAG BY xypos

Move the two VRTXS and all connected drafting primitives of the current span by the given displacements.

position can be a Design p-point, a 3D point or an explicit Sheet coordinate. A cursor hit can be used with all except the CLOSE, RADIUS, ASUB and STRAIGHT options. The position of a VRTX can also be constructed. Refer to Point and Line Construction for further information. If a VRTX is made coincident with the drafting point of another 2D primitive then a logical connection will be established and the DRAG command will affect the VRTX and the other 2D primitive.

The TO option defines the position of the VRTX without affecting the bulge factor and is thus similar to the standard DEF command. The CLOSE option positions the current VRTX to be coincident with the first VRTX of the OUTL and thus closes the Outline. This does not have to be the last VRTX though - subsequent VRTXs can be created.

The BY and DRAG BY options move the VRTXs at the start and finish of the span by the specified amount - bulge factor and curvature are unaffected. The THROUGH, RADIUS and ASUB options only define the bulge factor - knowledge of the through point, radius and angle subtended are lost. They do not change the position of VRTXs, only the curvature of the span.

The RADIUS option can have a negative value - this will result in a negative BULG and hence a span drawn in a clockwise direction. If the radius specified is not large enough to define the curvature of the span between two VRTXs then the command will be ignored and a warning message output, giving the minimum possible radius. By default the command gives the minor arc, the major arc being given by

SPAN RADius value MAJor

The command SPAN @ (or NEW VRTX SPAN @) gives a simplified way of defining the span. By default, you must define the TO position by a cursor hit, a straight-line span being assumed. The Outline Span Construction form will appear, giving you various span definition options.

The Q COMmon, HIGhlight, SKEtch POInts, SKEtch ORIgins and ID @ commands are all valid at OUTLs and/or VRTXs. Note that SKETCH ORIG ALL does not sketch all VRTX origins - only the origins of the owning OUTLs - i.e. the first VRTX below each OUTL.

Q DESCription is valid at OUTLs and VRTXs, giving details of origin coordinates and span radius and angle subtended (if appropriate). Q SPAN RADius and Q SPAN ASUBtended are valid at VRTXs only (but not at the first VRTX in an OUTL).

Creating Rectangles and Squares

Rectangles can be created using the commands:


ADEFine dfnpt1 dfnpt2	Defines a rectangle where dfnpt1 defines a position (2D, 3D, p-point etc) which is the centre of the rectangle, and dfnpt2 defines the position of a corner.
ASDEFine dfnpt1 dfnpt2	Defines a square where dfnpt1 defines the centre of the rectangle, and dfnpt2 defines the position of a corner.
SDEFine dfnpt1 dfnpt2	Defines a square where dfnpt1 and dfnpt2 define the positions of the corners

For example:


ADEF X400 Y400 X500 Y450	Defines a RECT 200 by 100 with its centre at X400 Y400 and a corner at X500 Y450.
SDEF X400 Y400 X500 Y450	Defines a RECT 100 square with one corner at X400 Y400 and the other at X500 Y500.
ASDEF X400 Y400 X500 Y450	Defines a RECT 200 square with its centre at X400 Y400 and a corner at X500 Y500.

These commands may also be used with the cursor, for example:

ADEFine @

A prompt requests two 2D points to be input.

All other operations refer to CIRCLE (CIRC) for further information.

STRAIGHT (STRA)

A STRA can be defined in two ways:


PTFA	-	Point references (2)
NLSTYLE	-	Note line style
NLCOLOUR	-	Note line colour
LENG	-	Length
ADEG	-	Angle in owner
TCOD	-	Type code (defines how to interpret attributes). Set either to ENDPOINT or MIDPOINT.

Basic Creation Methods

•

By defining the positions of the end-points (from which the values of length and angle can be derived if required).

•

By defining the position of the mid-point and values of LENG and ADEG (from which the positions of the end-points can be derived if required).

The commands:

NEW STRA
DEF @

results in two points being prompted for; a line is drawn between the two points and TCOD is set to ENDPOINT. Refer to Positioning (absolute) for the second method.

The command:

ODEF @

prompts for two points. The straight will be vertical or horizontal depending on the relative sizes of the horizontal and vertical offsets between the two points given.

Changing Length or Slope


LENGTH value [DESIGN]	Changing LENG or ADEG for a two-point STRA will move the ‘to’ point.
ADEG value
LENGTH @	Moves the From point of the STRA, changing its LENG and ADEG attributes.
ALENGTH @	Moves the To point of the STRA, changing its LENG and ADEG attributes.

Positioning (absolute)

A STRA may have its ‘from’ point, ‘mid’ point or ‘to’ point positioned or moved. Apart from the initial keyword (FPT, MPT, TPT) specifying which point you are setting the syntax is similar throughout, as the following examples show:


To position at a 2D (i.e. X,Y) position
FPT @ FPT X 50 Y -250	prompts: Enter a 2-d position
To position at a 3D (i.e. ENU position):
FPT POS @ FPT E12500 S5000 U0	prompts: Input a point in a View
To position on a p-point:
FPT ID @ FPT IDP @ FPT /PUMP2/N1 FPT P1 OF /PUMP2/N1	prompts: Identify element prompts: Identify design p-point

If the MPT command is used, the TCOD will be set to MIDPOINT. This is a single point STRAIGHT and must have its LENGTH set.

A straight can also be created by giving an orthogonal To point:

OPPT x 50 y 97
OTPT @

The straight will be vertical or horizontal depending on the relative sizes of the horizontal and vertical offsets between the From point and the To point.

Points on a STRA (FPT, TPT etc) may be identified using the command:

Q IDN @

Positioning (relative)

It is possible to move a STRA or one of its points by a given amount. For a single point STRA (i.e. one with a mid-point) there will be no difference between moving the STRA itself or its mid-point, but for a two point STRA moving its ‘from’ or ‘to’ point will cause its length and/or its slope to change; the position of the other point will remain unchanged.


BY @	prompts: or:	Input two points on a sheet Input two points in the same View

depending upon whether the STRA is currently positioned on a 2D point or a 3D/p-point.


	BY X55 Y-678 BY N500 W1200	STR As positioned at a 3D point cannot be shifted by an X,Y amount, and vice versa.
	DRAG BY @ DRAG BY X120 Y-45 DRAG BY S3500 D500	refer to comments for BY command
FPT BY @	prompts: or:	Input two points on a sheet Input two points in the same View

depending upon whether the point is currently positioned on a 2D point or 3D/p-point.


	FPT BY X55 Y-678 FPT BY N500 W1200	Points positioned at a 3d point cannot be shifted by an XY amount, and vice versa.
	FPT DRAG [BY] @	These commands change the position of the drafting point FPT DRAG TO @ to which the FPT is attached and hence will change the position of other primitives attached to the same point.
