Function
To create an "associative" dimension to one or two items. The g-dimension item type is 19. There is not a symbol/code to refer to g-dimension, so that SELECT, IDENTIFY etc. handle only the numeric item code 19.
Parameters
|
m= |
The colour of the g-dimension |
|
|
|
|
f= |
The fragment of the g-dimension |
|
|
|
|
typ= |
1 distance 2 angular 13 not used 14 orthogonal The “reference items” for this type of G-Dimension is the G-Node object only. An example would be as follows: partition gnode ... v1=inf(28) partition gnode ... v2=inf(28) gdimension typ=14,r1=v1,1,r2=v2,1,pos=p3,txt='#',w1=25,w2=25,arr=3,m=1 gdimension typ=14,r1=v1,1,r2=v2,1,pos=p4,txt='#',w1=25,w2=25,arr=3,m=1 |
|
r1= |
The first parameter i is the id of one of the items the g-dimension |
|
r2= |
points to; The second parameter i1 is : 0 if meaningless; 1 if it refers to the start point of a line or an arc; 2 if it refers to the endpoint of a line or an arc; |
|
pos= |
The position of the text |
|
|
|
|
w1= |
The displacement from the witness line, relative to the first item, from the item itself |
|
|
|
|
w2= |
The displacement from the witness line, relative to the second item, from the item itself |
|
|
|
|
aty= |
1 internal 2 external 3 external plus a support line |
|
arr= |
none |
|
|
1 simple chevron 2 triangle 3 filled triangle
|
|
txt= |
The string value of the g-dimension |
|
|
|
|
rat= |
The aspect ratio of the text |
|
|
|
|
cs= |
The text height and the tolerance height |
|
|
|
|
tol= |
The two tolerance texts (not used) |
|
|
|
|
ds= |
The decimal places |
|
|
|
|
box |
Whether the text should be "boxed" (not used) |
|
|
|
|
und |
Whether the text should be "underlined" (not used) |
|
|
|
|
da= |
The text angle (not used) |
|
|
|
|
j= |
The text justification (not used) |
|
|
|
|
dis= |
The displacement distance (not used) |
|
|
|
|
occ= |
The text occurrence (not used) |
|
|
|
|
sha= |
The constraint shape (not used) |
Note
The id of an item is returned by inf(28) function. This command does NOT work in 3D.
The items considered by this command are :
Point (17)
Single Line (3)
Construction Line (18)
Arc/Circle (11)
Update 11.7.0 (b05): The equal radius constraint requires two geometric entities and is identified by type 10. The geometric entities can only be circles or arcs. Meaning that, the radius of the first geometric entity is the same as the radius of the second geometry.
gdim typ=10,r1=id1,0,r2=id2
The equal distance geometric constraint requires four geometric entities and is identified by type 11. These geometric entities can be points, lines or infinite lines only. Meaning that the distance between the first and second geometry is the same as the distance between the third and fourth geometry.
gdim typ=11,r1=id1,0,r2=id2,0,r3=id3,0,r4=id4,0
A symmetric constraint requires three geometric entities, two items of the same type and the axis of symmetry which can only be a line or an infinite line.
gdim typ=12,r1=id1,0,r2=id2,0,r3=id3,0
Update 11.7.0 (b05): G-Dimension can have complex text. The case is when an inequality must be set to GDimension’s text. An inequality can be the definition of a range or a minimum or a maximum, that the actual value must match. The three supported formats are :
range [<minimum value>,<maximum value>]
minimum min:<minimum value>
maximum max:<maximum value>
where <minimum value> and <maximum value> can be expressions or values, for instance :
range [40,120]
[d1,120]
[d1/2,d1*2]
minimum min:40
min:d1
min:d1/2
maximum max:120
max:d2
max:d1*2
When the format min:<minimum value> is specified then the maximum value is BIG, a system variable internal to Eagle equals the maximum represented double. When the format max:<maximum value> is specified then the minimum value is 0.
The inequalities are pre-processed by Eagle and not passed to DCM. After an evaluation and after each step of a drag the inequalities are post-processed and if the solution found by DCM makes the actual value of an inequality unacceptable then an error is returned in the same fashion as for colliding constraints.
Examples
gdimension f=50,typ=4,r1=104,0,r2=106,0
gdimension typ=1,r1=101,1,r2=103,2,pos=j
gdim typ=11,r1=id1,0,r2=id2,0,r3=id3,0,r4=id4,0
gdim typ=10,r1=id1,0,r2=id2
