GiD_Geometry -v2 ?-no_model? create|delete|get|list|edit point|line|surface|volume <num>|append <data>
To create, delete, get data or list the identifiers of geometric entities:
...
-v2 mean version 2 of this command (deprecated version 1 documentation must be seen in help of old versions of the program), the flag really is optional and if missing version 1 is assumedreallyeed.
If -no_model flag is specified then entities are stored in a special container, it doesn't belong to the model
create: to make new geometric entities (the parameters are explained in the get command, the result of get can be used to create)
- GiD_Geometry -v2 create volume <num>|append volume|contactvolume <layer> {surface1...surfacen} {o1...on} ?<transformation_matrix>?
for contactvolume is necessary to specify the <transformation_matrix> : a vector of 16 reals representing a 4x4 transformation matrix that maps surface1 into surface2
- GiD_Geometry -v2 create surface <num>|append planarsurface|nurbssurface|coonsurface|meshsurface|contactsurface <layer> {line1...linen} {o1...on} <geometrical_data>
<geometrical data> depends of each entity type (see get command)
- GiD_Geometry -v2 create line <num>|append stline|nurbsline|arcline <layer> <inipoint> <endpoint> <geometrical_data>
...
- GiD_Geometry -v2 create line <num> | append nurbsline <layer> <inipoint> <endpoint> {-interpolate {p1_x p1_y p1_z ... pn_x pn_y pn_z} ?-tangents {t0_x t0_y t0_z} {t1_x t1_y t1_z}?}
- GiD_Geometry -v2 create line <num>|append stline <layer> <inipoint> <endpoint>
- GiD_Geometry -v2 create point <num>|append <layer> <point_x> <point_y> <point_z>
...
-v2 mean version 2 of this command and then return this data (deprecated version 1 documentation must be seen in help of old versions of the program)
- GiD_Geometry -v2 get point <num>
will return:
<layer> <geometrical data>
<layer> is the layer name
<geometrical data> the coordinates x y z
- GiD_Geometry -v2 get line <num>
will return:
<type> <layer> <p1> <p2> <geometrical data>
<type> can be: stline, nurbsline, arcline, polyline
<layer> is the layer name
<p1> identifier of start point
<p2> identifier of end point
<geometrical data> item depends of each entity type
stline: nothing
...
Will return the information of the render mesh of the line <line_id> as a list: {element_type element_num_nodes coordinates connectivities ts}
element_type: line
element_num_nodes: 2
coordinates: objarray with 3*num_nodes items of float with x y z of the render mesh nodes.
connectivities: objarray with element_num_nodes*num_elements of int with the connectivities of the elements (zero-based)
ts: optional objarray with num_nodes items of float with t space parameters (from 0.0 to 1.0) of each node. (it is optional, the array could have zero length)
- GiD_Geometry -v2 get surface <num>
will return:
<type> <layer> <trimmed> {l1 ... ln} {o1 ... on} <geometrical data>
<type> can be: nurbssurface planarsurface coonsurface meshsurface
<layer> is the layer name
<trimmed> 1 if the surface valid part is a trim of a bigger underlying shape, 0 else
{li...} objarray of integer identifiers of the surface lines (outer and inner boundaries)
{o1 ... on} orientation of the lines for the surface (0==natural orientation, along tangent, 1== opposite direction)
Note: turning left of a line with orientation 0 must points inside the surface.
<geometrical data> depends of each entity type
planarsurface: nothing
...
element_type: triangle or quadrilateral
element_num_nodes: 3 or 4
coordinates: objarray with 3*num_nodes items of float with x y z of the render mesh nodes.
connectivities: objarray with element_num_nodes*num_elements of int with the connectivities of the elements (starting by zero)
normals: optional objarray with 3*num_nodes items of float with x y z of the render mesh normals. (it is optional, the array could have zero length)
uvs: optional objarray with 2*num_nodes items of float with u v space parameters of each node. (it is optional, the array could have zero length)
- GiD_Geometry -v2 get volume <num>
will return:
<type> <layer> {s1 sn} {o1 ... on}
<type> can be: volume or contactvolume
<layer> is the layer name
{si} identifier of surfaces bounding the volume (including holes. the first must be the outer boundary)
{oi} are its orientation for the volume ( 0 along to the surface normal, 1 opposite)
...
- GiD_Geometry get point|line|surface <id> higherentity
Will return an integer >=0 with the counter of parent entities using this entity.
It is not defined for volume because this is the top category and doesn't has any parent.
list: to get a list of entity identifiers of a range or inside some layer
...
<filter_flags> could be: ?-unrendered? ?-higherentity <num_higher>? ?-material <id_material>? ?-layer <layer_name>? ?-plane {a b c d r}? ?-avoid_frozen_layers?
-unrendered flag is only valid for surface
-higherentity <num_higher> to filter the selection and list only the entities with the amount of parents equal to <num_higher> (integer >=0)
-material <id_material>to filter the selection and list only the entities with material id equal to <id_material> (integer >=0)
-layer <layer_name> to filter the selection and list only the entities with layer equal to <layer_name>
-plane <a b c d r> to list only the entities with center that match the plane equation a*x+b*y+c*z+d<=r
-entity_type <types_allowed> to list only the entities of a type contained in <types_allowed>, that must be a list of allowed types ("STLINE | ARCLINE |POLYLINE | NURBLINE | NURBSURFACE PLSURFACE COONSURFACE MESHSURFACE CONTACTSURFACE VOLUME CONTACTVOLUME")
