I use step file of UR3 downloaded from here for designing equipment with UR.
But there are dimensions differred from DH Parameter.
I hope that the demensions of STEP file are fixed.
Great observation! I am investigating this issue to see why there is a discrepancy.
How about your investigation.
There are differences from DH Parameter in CAD data other than UR3.
But they are no problem in UR3e and UR16e.
