Hello,I'm modifying Electric for use with new design technologies. This includes the use of non-manhattan wiring and I've run into two main problems that I'm having difficulty working around.
1. arc creation assumes manhattan layoutOnce I've created the arc at a multiple of 90 degrees, I can move the end around and the arc will remain in any angle I choose. However, it would be preferable if I could create it at the angle I chose from the start.
2. node creation occurs at odd locations and does not always work as a result. Once I have overlapping arcs where both are at an angle, the location the tool decides to create a contact node or other more or less complex node, it places them in odd locations and doesn't seem to actually connect them either. It always works if I place the connecting node around the head or tail of the arc but since I cannot reliably create a pin node where I want, or at all in most cases, placing it anywhere else on the arc fails so long as the arc is at an odd angle. If the arc is at a manhattan angle I have no difficulty and can then move the contact around and the wires angle themselves as needed.
It would also be useful if I could disable lambda rules and lambda grid placement for certain nodes and arcs.
Where in the code can I look to modify how these items are created so I can make my own rules as to where they are created and what angles are permitted at original creation?
