meet {+|-} {l=<vector>,<vector> |
c=<vector>,<vector>,<vector> |
o=<vector>,<vector>,<vector>,<vector>}
{,l|v} {,i} {,h} {,p<i> {,<nvar>} {,svar}}
Function
Select or identify a model item for manipulation by a search procedure along a line or arc. The search is exclusively a plan search and will only examine lines, construction lines and arc items. Intermediate items are returned on the basis of a maximum angle of search of 180 degrees clockwise. This allows the MEET command to be used to find intersection points and to identify profiles. MEET will return the closest item to the start of search, and if more than one item is the same distance, MEET will return the one which has the lesser clockwise angle.
Parameters
|
l= |
The line of search defined by two 3-D points. |
|
|
|
|
c= |
The arc of search defined by three 3-D points. |
|
|
|
|
o= |
The arc of search defined by four 3-D points for better accuracy. The fourth point should be the centre of curvature. If the first and third points are equal, this defines a circle where the second point should be on one side of the hemisphere, its position then defining the search as clockwise or anti-clockwise. |
|
|
|
|
L|v |
When a vector is searched, the entire LINES item will be selected. When v is used (or neither l nor v), an individual vector will be selected. |
|
|
|
|
I |
Just identify the item rather than select it. |
|
|
|
|
H |
Highlight the selected item by flashing it. |
|
|
|
|
P |
Record information about the selected item in attach points, starting at attach point i. pi+3 end of the selected item (arc), or centre of curvature (circle) |
|
var |
Record scalar information about the selected item in arithmetic variables starting at variable "var". The information is the item type (3 for a vector, 11 for an arc, 18 for a construction line), and the fragment of the item. |
|
|
|
|
svar |
Record an item type primer in a string variable for a subsequent call to MEET. The possible values are L (for line), C (for arc) and O (for circle). |
Once an item has been selected, the partition area is turned on at the end of the model workspace, and the selected item moved to this position, thereby making it available for subsequent manipulation by other commands. This may be overridden by prefixing command line parameters with + or -.
|
+ |
Once an item has been identified, it will be added to the partition, as the first item available for manipulation, thereby acting as an INCLUDE rather than as a SELECT. |
|
|
|
|
- |
Once an item has been identified, it will be extracted from the partition - if already selected - and considered as the last item in the foreground outside the partition, thereby acting as an EXCLUDE rather than as a SELECT. |
Examples
meet l=j,j,p1,v1
meet c=p1,p2,p3, h, i, p10,v50
meet o=p0,(0,200,0),(100,100,0),(0,100,0)
meet -l=p10,e500
Notes
Arc items lying in a plane other than the plan plane will be ignored by this command.
The Yes/No indicator will be set by this command: Yes if an item is successfully selected, No if no item is selected.
The Meet command allows the selection of Curve entities using its standard syntax. In particular this means that the MEET L= or MEET C= also search the workspace looking for the closest intersection vs. Curve entities.(Update V14 OCC)
