I'm new to Altium 17. Before that, i was using Altium 14 and things were pretty good. I have a problem about components on PCB.

In schematic, whenever i use "update PCB Document", components spread out everywhere of screen. Is there any solution to align them in order? Thanks.

This is the kind of thing I experience whenever my zero-registration in the component footprint is off by a lot. It looks like your components have a large difference from the Y-zero-point to the actual pad.

Try opening the footprint editor, press E for Edit, F for Set Reference, and choose Pin 1, Center or Location.

Pin 1 sets the origin in the center of your Pin 1 (obviously), Center sets the origin in the center of your component horizontally and vertically and Location lets you select an origin at any point on your grid.

Edit: Oh, and after doing this, delete the components from your layout and do another "Update PCB Document" to reimport the components to good default locations.

  • \$\begingroup\$ First of all, thanks for your interest. I got question to you. When you say "try opening the footprint editor," you mean footprint manager? (btw, i took these components from vault explorer, not from my library) \$\endgroup\$ – Griffo Mar 11 '17 at 21:33
  • \$\begingroup\$ I meant to edit the component via the PCB Library - I have no experience using the Vault functionality, unfortunately. \$\endgroup\$ – Araho Mar 11 '17 at 21:47
  • \$\begingroup\$ I don't think this is true, because he's not using the "Update from PCB Libraries," he's talking about updating the PCB when making changes to Sch. This is the correct behavior of Altium to place a new component off the board so that you can tell it's not been placed yet. If you modify an existing component, it will update it in place. You can go to the PCB panel, click "Outside Board Components" and select them all, then Tools --> Component Placement --> Arrange within Rectangle \$\endgroup\$ – Joel Wigton Mar 11 '17 at 22:12
  • \$\begingroup\$ Yes, @JoelWigton, but his problem is that the new components are placed outside of the maximum zoomed out area, so the components can't be selected. Your solution to the weird placement is a good one which I didn't know about (and an answer to the actual question asked - post it as an answer?), but it's still very nice (in fact, I'd call it vital!) to have a proper origin in a component :) \$\endgroup\$ – Araho Mar 11 '17 at 22:18
  • \$\begingroup\$ True that on the origin! \$\endgroup\$ – Joel Wigton Mar 11 '17 at 22:19
