How Wrong Scales in STEP Files Affect VTube
After an import of a STEP model of a tube. if you attempt to calculate a centerline and find that the calculation takes much longer than usual, and the resulting values are extremely large, then there is probably a problem in the original STEP file setup.
For example, this STEP file imported the following values:
The import required 28,539 loops which is much higher than normal.
How to Fix the STEP File in a Text Editor
Open the STEP file in a text editor and search for SI_UNIT.
In the import shown above the line with LENGTH_UNIT shows this:
#815=(LENGTH_UNIT()NAMED_UNIT(*)SI_UNIT($,.METRE.));
In this line, we can change the "$" character like this:
#815=(LENGTH_UNIT()NAMED_UNIT(*)SI_UNIT(.MILLI.,.METRE.));
Then save the file, then re-import the STEP file.
Import After Fix
This is how the imported part shows now:
