[VG_9645254]

hey, I am trying to automate the creo parametric through running parallel application using toolkit so i need a scale unit info (like model is in mm, cm , inches) for the model how i can find it

What you mean by model scale?

Do you want to get the size oft the model by x, y, z axis? Take a look at ProSolidOutlineGet()

Or you interesting to get view scale (zoom)? Or what?

hey  @YaroslavSin

I am looking for the scale base units (model is in mm, inches, centimeters).

[YaroslavSin]

Take a look

Toolkit: ProMdlPrincipalunitsystemGet()

OTK: pfcSolid::GetPrincipalUnits

thanks. I have one more query, how can I get an instance of pfcSolid to access GetPrincipalUnits() ?
