I use gravity sketch on my oculus to create form, and export an OBJ file with the mesh.
After, i want to convert this obj file to a solid in creo 5.
I open the obj file, and export it to a shrinkwrap. and when it calculate, no surfaces is create.
I don't know why sometime it work, and sometime doesn't.
I did successfull conversion in Creo 184.108.40.206.
thank you martin, just need to uncheck ignore quilts 👍
