It would be extremely helpful to update the Sketch Offset functionality to include a few things. A few other posts talk about selecting multiple entities and bi-directional offsets, but i have yet to see a post about trim/extend removing the offset dimension.
When you offset a line a certain dimension you get a fully constrained line based on a parallel constraint and dimension. As soon as you trim or extend that line the dimension is removed for whatever reason. Given the fact that you can't offset multiple selections at once unless they are chained this makes for a long process in many design instances. Currently to retain all the offset dimensions you need to sketch new lines with colinear or tangent constraints or trim/extend then re-dimension everything.
Thanks!
