Shape to Route Keepin Spacing

You sometimes get these kind of DRC's if you have been changing units (mm to mils etc) or changing board accuracry (number of decimal places). It also happens sometimes on translated designs. You could try reducing the number of decimal places to see if that helps. If it not too much pain you could also try re-creating the route keepin area using the z-copy command and also the planes shape (again using the z-copy command). This command allows you to copy the board outline contracting or expanding it by a specific amount to create another shape (keepin / keepout and etch planes).

Bump.

This issue continues to plague me.  Waiving the DRC is becoming not an option.  So frequently I waive the DRC, but then it comes back as a different DRC if I smooth the shape.  Very annoying. 

I use zcopy to create my route keepin by contracting the PCB Outline by 20 mils.  I then create ground and power pours using zcopy by copying the PCB Outline, again contracted by 20 mils, or copying the new route keepin without any contraction.  It doesn't matter which method I use.

I did notice that if the shape is not smoothed, I don't get the DRCs, they only show up when I smooth the shape.

I create all of my designs in mils.  Some of my footprints might have mm as its units, but the issue never surrounds parts.  It's always the dynamic shape pours that touch my route keepin boundary.

I have a design accuracy of 2 decimal places.  If I change it to an accuracy of only 1 decimal place, I don't get the DRC errors anymore.  I don't switch design units or accuracy once I've started a design.  Can anyone think of how I can get rid of the DRCs without decreasing the design accuracy?

Thanks in advance.

I have a similar issue if my z-copied shapes have arcs.  As a workaround, I z-copy my route keepin (contract 25 mils) then z-copy my plane shapes (contract 25.1 mils).  This 0.1 mil difference eliminates the DRCs for what I assume is a rounding issue.

 Hope this helps,

 Brilliant idea.  Thanks Randy.

If your shape is created before you add the route_keepin then you may occasionally get this. If it was created after the route_keepin the you won't see this because the default behaviour is for the route keepin to clip the shapes. There is a user preference that you can set (if you have added the keepin after the shapes) called shape_rki_autoclip that once the shapes are updated will clip them to the route keepin. This can affect performance though so won't make this a global setting for every board. Next time add the Route Keepin first.
