What is Ratsnest in PCB?
Connection lines, or Rats Nest (ratsnest), display is controlled in more than a few ways: The most direct way to turn on/off the display of all connection lines is to use the menu choice of the PCB editor: View ► Connections ► Show All (or Hide All)
How do I Unroute in Altium?
Position the cursor over a routed connection (or pad) belonging to the net you wish to unroute then click or press Enter. All routed track and vias for that net will be removed and replaced by the logical connections. Continue unrouting connections associated with other nets or right-click or press Esc to exit.
Why are my connections not showing in Altium?
In Altium I don’t have any connections (ratnest) showing. They were showing previously, and in the viewer they are ok. They should be visible after going to view->connections->show all but are not. This happens on all the boards and workspaces I open.
What does Altium tell you about air wires?
If I am not mistaken, Altium shows the air-wires only between the component and the nearest pad/track/via of the same net. It does not show airwires to all connections with the same net. That would leave to a VERY messy ratsnest that would not help with routing at all.
Where to find the vddc on an Altium?
The VDDC is a pin which is visible on the IC. Please find this unknown pin: pin Cxxx-x error while updating the schematic to PCB which I saw now. Also, i find a small circle on each component. how can I remove them? I am new to Altium. Hope to hear from you guys soon.
How to update PCB from schematic to editor?
In the PCB panel, make sure that “From-To Editor” is NOT selected. Make sure you update the pcb from the schematic, compile both to make sure there are no errors. Also check the component links to make sure your components are linked from schematic to pcb file. Don’t open up the PCB file without opening up the project.
