Any relation like Creo?
![zhongxuebo](https://profiles.onshape.com/6e416b831fd02c8b5b1d7fccb00294aaa0d0e83620d326c11d3848ab0597fbe3.png)
Question about relation.
For example I drew a line A which length is 20mm
Then I drew another line B, but the intent length should be 1/4 of former one. (5mm)
So later I can just change dimension A then update B automatically.
I already find some solution using variable, but that's not so flexible.
Maybe that's OK for simple model, but not so good for complex model.

Using the variable in a dimension
In the dimension field, enter # and the variable name (and optionally, as part of an expression (as shown below):
If you need variable act like creo relation then raise a improvement request for that. In near future we hope that this facility will be provided by Onshape.
