Hi,rnthe size difference in paraview is caused by the fact that the position and size is given in meters in our pvd output file while it is given in millimeters in the stl file. So in paraview the stl is shown exactly 1000 times bigger.rnOne way to solve this is by rescaling the stl in paraview.rnTo rescale the stl shown in paraview you can use the “”transform”” filter and scale 0.001. Size and position of the two will match now. Also, if you opened the pvd first, the camera is already in the right place.rnPeter
