Wrong scale

[almir89 1]

I have a problem with my CURA 4.8. Every time i import a model that i drew in my SOLID EDGE 2021 i get it in a wrong scale its alway larger or smaller then it shoud be and in the scale menu it says it's 100%.

For example if i draw a cube 100X100X100 mm my model in CURA 4.8 is 39x39x38mm and it says it's 100% scale.

Can anyone help me with this. Ty.

This sounds like somewhere in your workflow there is an inches to mm transition. The STL format does not specify a unit, so Cura (along with many other applications) assumes the coordinates in the STL file are in mm. It seems SOLID EDGE may have exported them in inches instead. See if there is a preference in SOLID EDGE to export in mm instead of in inches.

1000/25.4 = 39.37

So sometimes it's probably meters, and sometimes it's something other.

At any rate as ahoeben says it's likely in Solid Edge either in the drawing units, or it's an STL export utility setting.

Wow, you were right  guys. 

I loocked it up and even tho i drew my designs in mm's STL export was in inches, don't know how i missed that.

THX A LOT!!!
