Newb - vary only the diameter of tube

#1
Can I constrain the tube primitive so that I can adjust one value to change only its diameter? (By that I mean no changes to thickness or length.) Thanks.

Simple math me thinks - but 2 values are needed to keep thickness: You have an Inner+Outer radius and it´s ratio; outer minus inner is the thickness - what else do you need? You can use the entry field for calculation purposes BTW: so outer 2-0,25=1,75 for inner radius stands for a 0,25 thickness.

Cheers
