Free Schematic Archive

Welcome to our free archive of DesignWorks schematics, contributed by our users and gathered from public domain sources around the 'net.  Some commonly asked questions:

What do I need to read these files?

All schematics in this archive should be readable using DesignWorks Professional, DesignWorks Lite or LogicWorks products on either Windows or Macintosh or our Free DesignWorks Viewer (currently for Windows only).  Depending on which version you use, you might get a warning message saying "Warning: Some data items were not recognized and are being ignored" or something to that effect.  This can be ignored and should not affect the drawing.

Who owns these files?

All items in this archive are accepted and published only with the condition that they are public domain and free from any copyright restrictions.  To make a contribution, by which you certify that the preceding condition is met, just send it as an email attachment to schematic@capilano.com.

I downloaded a file and can't get the program to open it.  What's the problem?

If you have any trouble downloading or reading any of these files, try downloading the zip archive at the end instead.  Some browsers try and treat unknown file extensions as text, which will corrupt the file.
