You'd need to explain more how this would work as its not clear. Why not add 1 vertex, then add another, then stretch the segment in between the added vertices?
There are many things that cannot be undone/redone and flatten is one of them.
Just think, if you were to flatten a cell containing 1 million shapes, you have to store them in memory / in a file in case you want to later undo/redo them. Now flatten 10 such cells, all that data has to be saved on the undo stack…Sorry I don't see any attachment. Please email it to support@peardrop.co.uk
I guess this could be done – originally the path style was set to extend with begin and end extent as half the path width, as this is the default for regular nets in DEF. I'll make the change in v4.0.36
You'll need to create a techfile etc. yourself based on info you get from TSMC – TSMC data is TSMC proprietary.
The chop function calls the boolean code which always outputs a polygon (or rectangle of square). By wire I assume you mean a GDS path? It could probably be modified to detect that special case and cut the path if that's what you want, or alternatively a specific path cut command could be implemented.
Currently no – the merging is done using boolean operations, which always produces a polygon (or maybe a rectangle / square).
Also undo does not work yet for merge, this could be done though.
The code currently has a limit of 1024 via definitions, I'll extend that to 8192. That's a lot of unique vias!
Some minor bugfixes in this version, plus some improvements to the DXF reader to support arcs/ellipses etc.
