Hi, Please enable the trace length to be editable. It is important for so many features (ram, other components needing exact timings). To facilitate the implementation, we could think of it that way: 1) user puts a small non terminated wire. 2) edits the wire length. It tells the EE that we want something more from it: a specific length. 3) the wire disappears 4) the user clicks on the portions he want the line to be drawn. These are the leads. Between each lead, the soft calculates the remaining length to go and informs the user. 5) At the end, the user clicks toward the last point and the soft creates the line accordingly, shortening the last segment as needed to respect the required length. If the user messes up, he starts from the last good point again (by clicking on it; those coming next are discarded). It eases your dev time and is very easy for the user as well. What do you think about it? Thanks
