Hi Afranit, You can highlight the pins affected by a Net error: 1. Click on the **Design** button in the left hand panel; 2. Refresh the Nets using the little circular green refresh icon; 3. Click on the net(s) with the red highlighted cross; 4. Look through the list of affected pins in the bottom Net Pins section of the Design Manager panel 5. The affected pins are also highlighted in the PCB layout. You may also see Ratlines from any pins that are disconnected by the error which may help locate the problem. You can do a similar check for any DRC errors which may also help locate the problem. ![enter image description here][1] [1]: /editor/20170613/593ed01aab9e8.png
