How do you remove soldermask from a Trace (RF Track) ?

Jarez95

I have an RF track, how do I remove the soldermask above that specific track so that the RF performance is not affected. To be clear I dont want to remove the soldermask from the whole board and I hope this doesnt involve some kind of complex skill code solution. I am using SPB17.2-2016. 

Many thanks in advance.

    Its should be self explanatory, invoke the command, select the track you want to add the keepout to and fill in the form (PDF attached). I would add that this only creates a routekeepout, you would then need to copy that to the soldermask_top or _bottom layer. ClineToRouteKeepout_help.pdf

    Steve, does it put a soldermask dam between the component pads and the trace?  Looking at the pictures, it doesn't look like it does.  Here is what I normally do to make the contract mfg happy.  If I remove the gap, they always complain

    No it simply copies the cline path to a route keepout area on a lyer defined by the user, increased by a defined amount.
