What is D of bend?
Tube fabricators sometimes indicate the centerline radius using D of bend.
We say it by speaking three words: "D of bend" Some tube fabricators also say "D factor" to mean the same thing.
Calculation
It is a ratio calculated like this: Centerline Radius / OD
==How Is It Used?==
The D of Bend value helps fabricators know if the radius is tight or large compared to the OD. It serves as a general guide for how difficult it will be to create a quality bend. It helps fabricators know what kind of tooling will be necessary to achieve the bend.
It is also helpful for designers as a limit for what is practical.
Examples
In many applications, lower D of bend valued radii.
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:
