Imagine we import a PDB file like so (using the example from ref/format/PDB in the help directory):

Import["http://www.rcsb.org/pdb/download/downloadFile.do?fileFormat=pdb&compression=NO&structureId=1tf6", "PDB", ImageSize -> Medium]

The help file says that it should be possible to treat the imported PDB image as a Graphics3D object, but I can't seem to get it to display with other Graphics3D objects after using Import with the specification: 

Import["my_duplex.pdb", "Graphics3D"]

How would I scale and translate an imported PDB graphic and get it to display with other Graphics3D objects, like say a cylinder or sphere?

Use Axes -> True to get an idea of the scale:

i = Import["ExampleData/100d.pdb", "Graphics3D"]
Show[i, Graphics3D[{Red, Sphere[{0, 0, 0}, 400]}], Axes -> True]

  • $\begingroup$ @RVoight Try for example s = {0, 1}; k = 1/100; Show[i /. GraphicsComplex[a_, b__] :> GraphicsComplex[a k, b] /. Sphere[a_, b_] :> Sphere[a, b k] /. Cylinder[a_, b_] :> Cylinder[a, b k], Axes -> True] $\endgroup$
