content: Also, right click and do Shelf Selected. That way you can only shelf one instead of all

content: Quote from: skeematics21 on January 30, 2014, 03:44:33 pmAs Altium have progressed through their new releases, I have found that the removal of old polygon pours have sometimes not gone smoothly.I therefore recommend that you firstly save your finished design without the polygon pours. Then apply the polygon pours & save as (for example) yourpcb_polypoursJust my 2c worth.

content: Quote from: DerekG on March 12, 2014, 11:50:00 amI always save & commit to subversion before I do anything polygonish in altium. Definitely more reliable than hoping the undo works 100% all the time. That, and sometimes it's less work too than trying to get back to the last okay state.

content: Quote from: Mechatrommer on March 12, 2014, 02:27:41 pmAre you one of those mutually exclusivists I keep hearing about? Using a repository to save that known state only gives meextraoptions from which I can pick the best one to suit the job. It's not as if by using subversion I am suddenly unable to use the undo button. If pressing undo a few times gets me to a reasonable state, I do that. If undo messes things up I can go back to the last known good state. Basically I'll try and pick the option that is the least amount of work to get to the desired end result. And amusingly enough, using subversion results in less work, not more work.

content: my point was not about the way you do it. my point was about the "How do i undo a poly pour" not going smoothly in Altium.

content: In which case I probably didn't quite understand your reply.At any rate, a subversion commit before a poly pour (or any other large operation) is quite handy.

content: Hmm, never had any problems with polys, beside the fact that Altium handles them very clunkily. You can (usually?) route traces over a polygon as if it's not there, and repour as needed (always remembering to repour before generating fab files! argh!). In my flow, I only shelve to get the damn things out of the way (visual clutter, and also moving things around, layout and routing).If you have overlapping polys, one will pour over the other and the overlapping area can be indeterminate. To fix this, repour all, and set the pour order in the Manager (T, G, M). Or just try to avoid overlapping polys. I find this most useful when placing polys on a layer with a ground pour; the smaller polys need to pour first, otherwise the ground poly fills in and nothing works.I don't see any reason one should be handling polys by lucky saves and moving junk around. That sounds fantastically fragile. It is literally my businessto address or prevent situations with unwanted memory, hysteresis, undefined quantities and so on. Polys can be one such example, and approaching them in a way that prevents these unwanted aspects is the best approach.Tim

content: Yeah I have no idea what they're jibbering about. If I need to change something, which I do because I'm borderline obsessive about tweaking traces incessantly, I just shelve tweak and unshelve and it repours everything. No trouble at all. I do it so often, in fact, that I'm irritated that some of the steps do not have shortcut keys.The pour is disposable, the important bits are the rules that were used to pour it in the first place, and they don't go anywhere when you shelve.
