Just installed Designspark PCB, and try to create a schemaic. Â I follow this articale to add the net reference:How can I add Net References?
But unforunately, I can't find the "TO" component, and there does not have schema.cml library in my list, and there are only very few libraries available (DesignSpark, Itspice and XSpice).  I have searched my hard drive, it was found in C:\Users\Public\Documents\DesignSpark PCB 8.1\Library, and this folder is already listed in Folders page, but it was disabled.
I try to check the "Folder Enabled" checkbox , but it will be disabled automaticlly after pressing [Apply] or [Close] button.Â
I also tried to copy the schema.cml and schema.cmx to User folder, and it can be shown in the list now, and I can find the "TO" component.  However, the following error will be prompted when I add the "TO" component to my schematic.
Cannot find symbol "TO" in any library.
May I know how I can use those comonment in the library folder? Â Why can't the folder be enabled? Actually it can be enabled, but disabled after save. Â Is it a bug?
