Polygon Cutouts - Altium Discussion Forums

Polygon is wrongly poured over polygon cutout - Altium Discussion Forums:

Workaround for Polygon Cutouts in AD14.3.14

"I tried this with a new, blank board.

I placed a polygon and then, a polygon cutout inside. The polygon cutout is not working. Then i have changed it to board cutout, and it works as expected. When i change it back to polygon cutout again, it works !!!

By the way, I found out, that it works, if you move the polygon."

Rooms - For Clearance Exceptions

Rooms are useful for creating exceptions. 

For example this Ethernet design called for 18 mils of clearance from the differential pairs to adjacent copper pours.

The diff pair nets were placed in class and a clearance rule was created to hold polygon pours back 18 mils.

This took care of the 18 mil (~3 x W) copper clearance requirement.


However as shown above, now there is a clearance error where the differential pairs connect to U500.

We can use a room to define a clearance exception for the differential pair at U500.

Define the Room

Design > Rooms

Tip: Use Shift + Click to Select an Existing Room

Tip: Select a handle on the Room > Drag Handle > Tab Key

Take note of the settings used for the room above, specifically:

Name RX_TX_ROOM

Not InComponent('U500') 

'Keep Objects Outside' 


Clearance Rule

That's It.

Drill Chart Properties

Selecting the new Drill Chart Properties can leave you frustrated.

Right Click the upper left handle in the table's corner to bring up the properties dialog.

Good luck, it's kinda of random that you will bring up drill table properties, more often than not you end up selecting a track in the table's frame.

Please let me know if you have a better method.

That's it.
