Setting "Units and Transform" values via Navisworks API

By Naveen Kumar

Question: I'm trying to modify the Model Units, Origin, Rotation, and scale values of each appended 3D model. Is it possible to change these values via Navisworks API?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Answer: Yes, it is possible to change these values using SetModelUnitsAndTransform Method. Please take a look at the below sample code

  
  DocumentModels models = doc.Models;
//Get the required model from DocumentModels
  Model model;

  Transform3D oldTransform3d=model.Transform;
  Transform3DComponents transform3dComponents = oldTransform3d.Factor();

//Get Values
  Vector3D originVector3D = transform3dComponents.Translation;
  Vector3D scaleVector3D = transform3dComponents.Scale;
  Rotation3D rotationVector3D = transform3dComponents.Rotation;

//Set Values
  transform3dComponents.Translation = new Vector3D(origin_X, origin_Y, origin_Z);
  //Eg: new Vector3D(10,10,10);
  
  transform3dComponents.Rotation = new Rotation3D(new UnitVector3D(0, 0, 1), 0.872665);
  //Here 50 degree=0.872665 radian
  
  transform3dComponents.Scale = new Vector3D(scale_X, scale_Y, scale_Z);
  //Eg: new Vector3D(2,2,2);
  
  Transform3D newTransform3D = transform3dComponents.Combine();

//Change model units value
  Units units = Units.Meters;

  models.SetModelUnitsAndTransform(model, units , newTransform3D, true);
