GetNearestPlane(pnt)
Function returns the name of the nearest plane to the pnt point of the selected object.

pnt – variable of the Point type.

Example:

function OnConnect{ if(obj.strTheType == “StdJointParts”){ // … } else { strName = GetNearestPlane(pntOrigin); if(strName != UnknownValue){ SetGeomConstraint(INSERT, CODIRECT, obj, WP1, strName, 0); NoVectorSelect = 1; Handled = OBJ_HANDLED; } }
}

//variant 1
findNearest( pnt, Name1, Name2, … , NameN
)
//variant 2
findNearest( pnt, arrName, arrIndexStart, arrSize
)

Returns an index of the nearest point or plane according to the parameters types, specified with the Name1, … NameN or arrName names.

Function supports two types of call:

1) the particular names of the public parameters are specified as arguments

2) the array of the public parameters with the starting index for searching and calculating a number of the array elements, is specified as the arguments

pnt – variable of the Point type.

Name1, NameN, arrName – names of the public parameters of the selected object

arrIndexStart – starting index for searching in the array

arrSize – array size

Example:

//variant 1 rNearest = findNearest(pntOrigin, obj.WP1, obj.WP11, obj.WP21); // rNearest takes 0, 1 or 2 values
//variant 2 rNearest = findNearest(pntOrigin, obj.WP, 1, 4); // rNearest takes 1, 2, 3 or 4 values

//variant 1
nearestPlaneName( pnt, Name1, Name2, … , NameN
)
//variant 2
nearestPlaneName( pnt, arrName, arrIndexStart, arrSize
)

Returns an index of the nearest point or plane according to the parameters types, specified with the Name1, … NameN or arrName names.

Function supports two types of activation:

1) the particular names of the public parameters are specified as arguments

2) the array of the public parameters with the starting index for searching and calculating a number of the array elements, is specified as the arguments

pnt – variable of the Point type.

Name1, NameN, arrName – names of the public parameters of the selected object

arrIndexStart – starting index for searching in the array

arrSize – array size.

Example:

//variant 1 strNearest = nearestPlaneName(pntOrigin, obj.WP1, obj.WP11, obj.WP21); // strNearest takes “obj.WP1”, “obj.WP11” or “obj.WP21” values
//variant 2 strNearest = nearestPlaneName(pntOrigin, obj.WP, 1, 4); // strNearest takes “obj.WP1”, “obj.WP2”, “obj.WP3” or “obj.WP4” values

restoreBasis(vecOld, vecNormal, vecNew);
Function converts an old basis according to the new position of the vector.

Following combinations are applied in the next order:

(x, y, z, newX)

(y, z, x, newY)

(z, x, y, newZ) vRrev – previous vNext in the XYZ

MakeVectorsFromView(lViewType, vecDirection, vecPlane);
Sets the position of the vectors from the view type

Example:

MakeVectorsFromView(VTOP, vecDirection, vecPlane);
setBasePlaneForSelect(planeName, vecPlane = vecPlane);
Sets a plane coordinate system, where the SelectParam will work, i.e. the rXcoord, rYcoord will depend on this system.

Applying. When selecting non-symmetrical details whose selection direction depends on the fixed plane and the distance is calculated from any plane; for example, the standard ends of the arbors, not from the pntOrigin.

Example:

setBasePlaneForSelect(WP1);
Used for connecting the ends of the arbors.
