Can't Load Old Schematic

Warren, you're right!  And going to the specified coordinates I found that there was a component missing in the edited file.  So I'm hoping that just replacing/reconnecting this component will fix the problem completely.

I hadn't tried setting the grid to mm because I didn't think it was that big, but it is:  B size is 11x17 inches, so the width in mm is about 430.

Thanks,

Greg

might be to change the signal name on these 2 lines to some new, unique

name.  I haven't tried that yet.

 

The 2nd error message is: <instance part="SUPPLY1" gate="GND" x="332.74"

y="172.72"/>.  Note that this has coordinates in it, which I presume

would indicate where the particular connection to this signal occurs,

but what coordinate system is it?  I can only set the grid to 'normal'

units such as inches or millimeters.

 

The coordinate system for sch file is millimeters

You can verify this for your self. Set the sch grid to MM. next locate a

part on the schematic, say R1 and view its INFORMATION. Record its xy

location

Now look for the part in the file in the 'instances> instance' section.

It will be towards the bottom. It will have the same XY there.

Quickest way to find the right line is search in the file for "x="60.96"

inserting the x you noted from INFORMATION. THere will likely only be

one fine result, the one you want.

Setting the grid to inches, performing a save and then inspecting the

file again, there will be no change to the xy location of the part

proving it's mm.

Opening my mouth where I might not know what I'm talking about, but here goes anyway! 

If you open that file with a text editor, do you find "SUPPLY1" listed twice in that part?  It may be as easy as using your editor to change that name, or delete the extra definition line.

Make a backup first...
