Greetings all,

I've come across a problem with polygon pours that I can't seem to find a solution for:

Previously in Protel 99SE and also in DXP 2004, when I pour a polygon, any component pad on the same net is connected as per the design rules, using the heat relief style. At the same time, vias on the same net were directly connected (with the "pour over same net" setting in the polygon properties).

Now in Altium 10, the vias are following the same heat relief connect style as component pads. Its resulting in some unconnected net violations and I can't find a way to change it. The Wiki section on polygons doesn't shed any light and if I try to make a new poly connect design rule, I can't seem to select via objects in the query.

Does anyone know if it can actually be done and if so how?

Thanks,
Steve

It's been some time since I used designer 10 and I don't have an active license for it at the moment. I've done what you're asking about and i had no problems.
Maybe something to do with tenting?

Yes, I do this all the time. you have to make a new (higher priority) polygon connect rule, with IsVia in one of the critera boxes, and direct connect as the rule contents.

One can do the same thing with power planes.

Yep; worked like a charm. Thanks again.

Don't suppose I could trouble you for another pearl of Altium wisdom?

Doesn't appear that I can separate the visible grid from the snap grid as I could in previous versions. What I would like to have is a snap grid of say 0.25mm with visible grids of 1mm & 10mm.
I've added new custom girds but, even though they over ride the global grid, they follow the same behavior where snapping is done to the finer unit.

Is it possible or something I'll just have to get used to?

I took a quick look and couldn't figure out how to do it. I've never had the need though, so it may be possible.

I usually set my grid to 10 or 20 mil when I'm placing parts then change it to 5 mil when routing.

You might try searching Altium's forums if it's important to you. They've got a pretty terrible interface, so I try to avoid it when I can.

never used seperate grids.
you could indeed put a question onto the Altium forum.
beware indeed that the visible interface is terrible
