I want to create a centerline for my patient specific geometry. I have successfully created in .vtp format using VMTK sotware.

code:

vmtksurfacereader -ifile “E:/geometry/v3\_shortIliacExtendIMACAP\_V2\_vtmk.stl” --pipe vmtkcenterlines -seedselector openprofiles -ofile “C:/Users/Dhaya/surface\_centerlines.vtp”

will it possible to create or convert to .stl format in ascii mode?

Note: The above generated .stl file is imported into the Ansys CFD Post.

Operating system: Windows 10  
Slicer version: VMTK 1.4.0 software  
Expected behavior:  
Actual behavior:
