NET high analysis of the "Revit API" beam

The principle is to take a point from the locationcurve of the beam and then project it to the upper surface of the plate. If there is a projection point, and then projected from the projection point (on the plate) to the bottom of the beam, the distance can be obtained if there is a projection point.

The first condition of using this analysis is that the beam is above the plate, do not forget!

varBeambottomfaces =faceutils.getbottomfaces (beam); //This method is self-encapsulated if(NULL! = Beambottomfaces &&Beambottomfaces.any ()) {    varBeamlocationcurve = Beam. Location asLocationcurve; varBeamcurve =Beamlocationcurve.curve; if(Beamcurve! =NULL)    {         if(Beamcurve isLine ) {Beamcurve=Getextlocationcurve (Beamcurve);         //If Locationcurve is line, it is best to do an extension algorithm, or some beams because of deductions, Locationcurve easily missing part } varBeampoints =getpoints (Beamcurve, Pointrange); //pointrange is the pickup interval. if(Beampoints! =NULL&&Beampoints.any ()) {              varFloordatalist =Getbeamfloorspaircore (beambottomfaces, beampoints, floors);    //floors for building boards } }}

Extension of Locationcurve:

Private Curve Getextlocationcurve (Curve Curve) {     = XYZ. Zero;      = XYZ. Zero;      if  is Line )     {          as line  ). Direction.negate ();            as Line ). Direction;     }       = Line.createbound (curve. Getendpoint (0) + 1E3 * dir0, Curve. Getendpoint (1) + 1E3 * dir1);       return Extcurve;}

On curve, press Pointrange to select a point:

PrivateList<xyz> getpoints (Curve Curve,DoublePointrange) {       varPoints =NewList<xyz>(); varBeamlength =curve.       Length; varPointsnumber = beamlength% Pointrange = =0? ((Beamlength/pointrange)-1): Math.floor ((Beamlength/pointrange));  for(vari =1; I <= Pointsnumber; i++)       {          varPoint = Curve. Evaluate (Pointrange * I,false); Points.       ADD (point); }       returnpoints;}

Get Distance:

PrivateList<keyvaluepair<element, LIST&LT;KEYVALUEPAIR&LT;XYZ,Double>>>> Getbeamfloorspaircore (list<planarface> beambottomfaces, ienumerable<xyz> beamPoints, List<element>floors) {      varFloordatalist =NewList<keyvaluepair<element, LIST&LT;KEYVALUEPAIR&LT;XYZ,Double>>>>(); //look for the plates under each structure beam      foreach(varFloorinchconstructionfloors) {         //gets the top point coordinates of the board         varFloortopfaces =faceutils.gettopfaces (floor); if(NULL! = Floortopfaces &&Floortopfaces.any ()) {              varDefaultfloororiginz =Floortopfaces.firstordefault ().              Origin.z; foreach(varTfinchfloortopfaces) {                   varOriginz =TF.                   Origin.z; if(Defaultfloororiginz <=Originz) {Defaultfloororiginz=Originz; }              }                                 varDefaultbeamoriginz =Beambottomfaces.firstordefault ().              Origin.z; foreach(varBfinchbeambottomfaces) {                   varOriginz =BF.                   Origin.z; if(Defaultbeamoriginz >=Originz) {Defaultbeamoriginz=Originz; }              }              //the plate is below the beam .              varIslower = Defaultfloororiginz <Defaultbeamoriginz; if(islower) {varDataList =NewLIST&LT;KEYVALUEPAIR&LT;XYZ,Double>>(); //a point on the beam can be projected onto the board.                   foreach(varPointinchbeampoints) {                       foreach(varTfinchfloortopfaces) {                           varIsproject =TF.                           Project (point); if(NULL!=isproject) {                               //the coordinates of the points projected onto the board                               varProjectpoint =Isproject.xyzpoint; //the distance from the projection point to the point on the beam                               foreach(varBfinchbeambottomfaces) {                                   varbp =BF.                                   Project (Projectpoint); if(NULL!=BP) {                                       varDistance =BP.                                       Distance; Distance=unitutils.convertfrominternalunits (distance, displayunittype.dut_millimeters); Distance=Math.floor (distance); varPointanddistance =NewKEYVALUEPAIR&LT;XYZ,Double>(projectpoint, distance); DataList.
