Working with other CAD systems I have found the notion of TAGS or PROPERTIES that can be added to ANY design element extremely powerfull.
Some examples : adding a flag to drill-hole so it will be processed by the export script in a special way
for example ; nibble this, laser this, or drill-tolerance
Adding a remark/text note to a part on a PCB (like, watch out, keep close to edge)
Adding a tag to a trace : '.impedance=50' or '.trace=automatic' '.IPCNET=88912'
Adding tags to filled polygon, about clearance to board edge, not just other copper, maybe same net?
Adding a special flag to a everything in a selection so you can get back to it later.
Using a filter based on tag and tag value.
The important thing is that you need to be able to set/get the tags/properties inside the scripting too.
You can use the tags to select, and move, copy in a flexible way.
By introducing some 'standard' tags about 'layers' and 'temporary-selection' you can do many things.
My examples are a bit lame now, but I will add some serious use case based on thing I see in other software. |

TAGS or PROPERTIES that can be added to ANY design element extremely powerful.
Some examples : adding a flag to drill-hole so it will be processed by the export script in a special way
for example ; nibble , laser, or drill-tolerance
Adding a remark/text note to a part on a Component (watch out, keep close to edge, any free text)
Adding a tag to a trace :
'.impedance=50'
'.impedance_tolerance=5'
'.trace_routed=automatic/manual'
'.IPCNET=88912'
'.origin=board.brd,line=777'
Adding tags to filled polygon, about clearance to board edge, not just other copper, maybe same net?
Add a tag so the item(s) will be excluded from the DRC?
Adding a special flag to a elements in a selection, so you can get back to it later, using a filter based on tag and tag value.
When you share a design file, you can tags for the other person, todo-items on some elements.
The important thing is that you need to be able to set/get the tags/properties inside the scripting too.
You can use the tags to select, mark, and move, copy in a flexible way.
Also tagging an item with : '.look_at_this_BOB' will allow Bob to quickly find what you need him to see.
By introducing some 'standard' tags about 'layer', 'tolerance'' 'library-origin' and 'selections' you can do many things.
You could offer 'temporary' and 'permanent' tags, the first will not be saved, the other would end up in the board file.
