Using Solid Region

So here I'm using a solid region as according to the reccomended PCB layout for the IC that I'm using (data sheet link below).  I want to make sure before I have the board made, the solid region will 1) Be connected to the pads its under (I made it have the same net) and 2) that only the actual solder pad of the components will be exposed on the board, if the whole solid region were exposed it would be difficult.  If these things are not as intended, how would I change them so they would be? Current layout: ![image.png](//image.easyeda.com/pullimage/0FAVkHiU5UJB9JYEHaQyrTM6xLYsH3iYzuumpkZH.png) Intended layout: ![image.png](//image.easyeda.com/pullimage/k6AydhgOYRbrmougTeHlqTO1flKuQYz2jHplhy50.png) Datasheet: [http://www.ti.com/lit/ds/symlink/tlv62130a.pdf](http://www.ti.com/lit/ds/symlink/tlv62130a.pdf) Thanks

To check if you have the correct connectivity according to your schematic please use the Design Manager in the left hand panel. If you read the Tutorial and play with it, you'll see how it works and how it can help you. Also, you can check that the whole of a net is connected by clicking on a track or pad and pressing the H key. The whole of the net should light up. Your project is private so only you can see it. Some of the pin connections look very different from the example you have shown but without a schematic it is not possible to check any further.

Best way to check if the solder pads are exposed, holes are in the right place and other things like that, is to use the photo view.  Usually shows up something I've messed up.

Then generate the Gerbers, download them and check them using gerbv. For detailed checking, please see especially (4) and (6) in: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f)

Also you should be able to see how solid region is built by using Shift+B to rebuild copper area. Also Shift+M to remove copper area from drawing.

Solid Region is not the same thing as Copper Area.

In PCB LIb, building a PCB footprint, how do you connect a solid region to a net?  Like a heat sink area that goes with the part, NOT part of the PCB, but always shows up on the PCB any time you place the part.  There is a Solid Region tool, but I don't see how to connect it to a net. -Electronut42

@electronut42 When you placed it at PCB , you can set its net name. if you draw it at PCBlib, and after placed at PCB , you can not edit its net. you need to add solid region at PCB directly.

@electronut42, Any copper in a PCB Lib (PCB Footprint) that is not a pad cannot be assigned a pad Number and so cannot be assigned a netname when placed in a PCB. Therefore any tracks, solid regions or vias used in the construction of a PCB Lib will generate a DRC error if an attempt is made to connect a net to them when that PCB Lib is placed in a PCB. If a PCB Lib needs some sort of irregular structure made in copy then use an arrangement of one or more overlapping pads all assigned the same pad number. These pads may be a combination of Multi-Layer, Top and Bottom layer, Round, Rectangular, Oval and Polygons.
