I am very new to PCB Editor and I'm sure I will end up posting a fair amount of Forum questions. The first is that I am trying to do a manual place of components in the PCB Editor, and my tree view doesn't seem to be appearing properly. In all the examples I have seen, there are check boxes next to the reference designators. My tree view shows all the components, but there appears to be no way to select them as there are no check boxes in my view. If I highlight the refdes name and then click "Hide" to try to place the component, nothing happens.
It is worth noting that I am using version 16.3 on Windows 7. This has already produced a few bugs that needed correction. I assume this is the same situation. Any suggestions?
This should no longer be a problem using v16-3-85BB or later releases (Use Help >About to determine your specific version). If you are using an erlier release use the workarounds below.If you are using a later release than this and still encounter the issue I'd suggest contacting Cadence Customer Support.Fromhttp://www.cadence.com/Community/forums/p/16421/757222.aspx#757222"djhutchi"We have seen this issue on certain Windows 7 laptops…try opening Control Panel\All Control Panel Items\Display & change to a smaller size – the default 125% might be the issueCadence Online Support Solution 11630192"Windows 7 offers a Large Scale (120 DPI) option.

Thanks for the quick reply! It looks like I'm running 16.3 p006 (v16-3-85F). I changed the Windows Display to 100 from 125, and sure enough, the check boxes show up now. The only interesting thing is that in the place window, the "Hide" button disappeared. This isn't a big deal - I will just move the window off to the side while I'm placing. It's interesting that it happened though.
In reply to ChrisL2:
The Hide button normally disappears when you are in Placement Application Mode. There are three, General, Etch and Placement. They are the three green icons in the left hand corner or you can access them from the RMB - Application Mode menu.
In reply to steve:
You're absolutely right. Hide reappears in General and Etch modes. Thanks for helping me out.
I have a similar problem to the OP. I am trying to place a mechanical symbol (mounting holes, which I have done before on this board and others) on a board where I have already placed and routedmy components.
Unfortunately, when I do Place-> Manual... like I did before, I get the same message in the command "Select elements to place using tree view.", but I can't see it!
I know the tree view its referring to, but I don't seem to be able to get that view to come up again, no matter what I do. Any suggestions?
In reply to sakeser:
Close Allegro, try locating your pcbenv folder (normally in %HOME%\pcbenv) and rename it to pcbenv_old. Then restart Allegro and see if that helps.
That did it, thanks a lot!
I just noticed that by renaming the old pcbenv folder, Iost the autorouter menu.
Is anyone aware of what causes this and how I can recover my precious autorouter functionality?
